Answer:
x=[tex]\frac{13}{6}[/tex]
Step-by-step explanation:
[tex]6( x - 1) - 12 = - 5 \\ ⟹ 6x - 6 - 12 = - 5 \\ ⟹ 6x - 18 = - 5 \\ ⟹ 6x = - 5 + 18 \\ ⟹x = \frac{13}{6}[/tex]
Hi there! :)
Answer:
[tex]\huge\boxed{x = \frac{13}{6}}[/tex]
6(x - 1) - 12 = -5
Begin by adding 12 to both sides:
6(x - 1) = -5 + 12
6(x - 1) = 7
Divide both sides by 6:
6(x - 1)/ 6 = 7 / 6
x - 1 = 7/6
Add 1 to both sides:
x = 7/6 + 6/6
x = 13/6.
A teacher wants to earn $1500 per year in supplemental income from a cash gift of $16,000. She puts $6,000 in a credit union that pays 7% annual interest. What rate must she earn on the remainder to achieve her goal
Answer:
6,000 * .07 = $420 per year
Therefore the remaining 10,000 must earn 1,080 per year
Total = Principal * (1+rate)^years OR
Total = 10,000 * 1 + rate
1,080 = 10,000*rate
1,080 / 10,000 = rate
rate = .108 OR rate = 10.8 % per year

A 12 1/2 mile stretch of road needs repaving . A company bids on the repaving project saying they could replace 2 1/4 miles of road per week. How many weeks will the company take to completely replace the stretch of road?
2 1/4 miles => 1 week
1 mile => 1 ÷ 9/4
( 9/4 is an improper fraction of 2 1/4 )
12 1/2 miles => ( 1 ÷ 9/4 ) × 25/2
= 50/9
= 5 5/9 weeks
( 25/2 is an improper fraction of 12 1/2 )
Therefore, it will take 5 5/9 weeks for the company to replace the stretch of road.
( you can round it off to 6 weeks if the qn specify to give to the nearest whole number )

The following statements are about finding a midpoint of a segment in the complex plane. Which statement is false?
The midpoint is the average of the endpoints.
First add the endpoints and then multiply by 1/2.
First subtract the endpoints and then divide by 2.
The midpoint of complex conjugates will lie on the x-axis.
Answer:
C.
Step-by-step explanation:
First subtract the endpoints and then divide by 2.
The incorrect statement about the midpoint of a segment in the complex plane is: First subtract the endpoints and then divide by 2.
What is complex number?"It is a number of the type a + ib, where a, b are real numbers and [tex]i=\sqrt{-1}[/tex]"
What is midpoint formula in the complex plane?"The midpoint of two complex numbers a + bi and s + ti is [tex]M=\frac{a+s}{2}+i(\frac{b+t}{2} )[/tex]"
What is complex plane?"It is formed by the complex numbers, with real axis (x-axis in coordinate plane) and imaginary axis(y-axis in coordinate plane)"
For given question,
We know that the midpoint of a segment in the complex plane passing through two complex numbers a + bi and s + ti is given by [tex]M=\frac{a+s}{2}+i(\frac{b+t}{2} )[/tex].
This means, the midpoint is the average of the endpoints.
or to find the midpoint first add the endpoints and then multiply by [tex]\frac{1}{2}[/tex]
We know that the complex conjugate of a complex number x + iy is x - iy.
if we find the midpoint of a segment passing through these points, then it would be,
[tex]M=\frac{x+x}{2} + i (\frac{y-y}{2})\\\\M=x+0i\\M=x+0\\M=x[/tex]
This means the midpoint would lie on the X-axis.
Therefore, the incorrect statement about the midpoint of a segment in the complex plane is: First subtract the endpoints and then divide by 2.

my ones digit is 2 more than my thousand digit. the sum of my ones and thousand is my hundreds digit. 3 less that my hundreds digit is my tens digit. my Hundreds thousand and ten thousand are the same. guess what number I can be.
Answer:
No answer. See below.
Step-by-step explanation:
This number is in the ten-thousands, so it has 5 digits.
Let the number have the form
abcde, where
a = ten-thousands digit
b = thousands digit
c = hundreds digit
d = tens digit
e = ones digit
"my ones digit is 2 more than my thousand digit."
e = b + 2
"the sum of my ones and thousand is my hundreds digit."
e + b = c
"3 less that my hundreds digit is my tens digit."
c - 3 = d
"my Hundreds thousand and ten thousand are the same."
c = b = a
We have 4 equations:
e = b + 2
e + b = c
c - 3 = d
c = b = a
Using the last equation, replace every c and b with a in the first 3 equations.
e = a + 2
e + a = a
a - 3 = d
Using the second equation, subtract a from both sides.
e = 0
Substitute e = 0 in the first equation.
0 = a + 2
a = -2; b = -2; c = -2; d = -5
Since a digit cannot be negative, there is a problem with this question.

What is the length of the hypotenuse, x, if (20, 21, x) is a Pythagorean triple?

41
42
Answer:
B
Step-by-step explanation:
The length of the hypotenuse, x, if (20, 21, x) is a Pythagorean triple is 29.
What is Pythagorean triples?Pythagorean triples are represented as the triple (a, b, c) where a represents the perpendicular side, b represents the base and c represents the hypotenuse.
Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.
c² = a² + b²
Here a = 20, b = 21 and c = x.
x² = 20² + 21²
x² = 841
x = √841 = 29
Hence the length of the hypotenuse, x, is 29.

Answer:
A. x + 46 = 2,749
Step-by-step explanation:
The total MUST be 2,749 as it is the amount of books added and the amount of books that were present from before; therefore, the books in total is 2,749.
x remains there, for the library had already had (x) amount of books from before.
46 is added to x because 46 is the amount of books acquired, in addition to (x) amount of books.
Therefore, the answer is x + 46 = 2,749

Use the number line below, where , RS=6y+2, ST=15y+9 and RT=5y-13. Find
the value of RS, ST, and RT *
Answer:
RS = - 7
ST = - 13.5 = - 13½
RT = - 20.5 = - 20½
Step-by-step explanation:
From the question given above, the following were obtained:
RS = 6y + 2
ST = 15y + 9
RT = 5y - 13
To obtain RS, ST and RT, we must first obtain the value of y. This can be obtained as follow:
From diagram above, it is evident that:
RT = RS + ST
RS = 6y + 2
ST = 15y + 9
RT = 5y - 13
5y - 13 = 6y + 2 + 15y + 9
5y - 13 = 6y + 15y + 2 + 9
5y - 13 = 21y + 11
Collect like terms
5y - 12y = 11 + 13
- 16y = 24
Divide both side by - 16
y = 24/ - 16
y = - 1.5
Finally, we shall determine RS, ST and RT as follow:
RS = 6y + 2
y = - 1.5
RS = 6(-1.5) + 2
RS = - 9 + 2
RS = - 7
ST = 15y + 9
y = - 1.5
ST = 15(-1.5) + 9
ST = - 22.5 + 9
ST = - 13.5 = - 13½
RT = 5y - 13
y = - 1.5
RT = 5(-1.5) - 13
RT = - 7.5 - 13
RT = - 20.5 = - 20½

= 11 miles
2x+3=15=? .FIND X AND EXPLAIN WHY?
Answer:
x = 6
Step-by-step explanation:
The properties of equality let you add the same thing to both sides of the equation without changing the value of the variable. The same is true for dividing both sides of the equation by the same thing. These properties can be used to find the value of the variable.
Solution2x + 3 = 15 . . . . . . given
2x +3 -3 = 15 -3 . . . . add the opposite of 3 to both sides
2x = 12 . . . . . . . . simplify
2x/2 = 12/2 . . . . . . . divide both sides by 2
x = 6 . . . . . . . . . simplify
CheckThis value of x can be checked in the original equation to see if it makes the equation true:
2×6 + 3 = 15 . . . . . . substitute 6 for x
12 +3 = 15 . . . . . . . . a TRUE arithmetic fact
The value of x is 6, because that value makes the equation a true statement.

y =
Answer:
-1/2 + 2.
Step-by-step explanation:
What is the order of the steps to solve for x in the equation 3x - 6x - 7 = 29?
Use the addition property of equality.
Use the division property of equality.
Combine like terms.
Answer:
3x - 6x - 7 = 29 Given
-----------------------------------
3x - 6x -7 = 29
+ 7 + 7 Addition property of equality
3x - 6x = 36
--------------------------------------------------------------
3x - 6x = 36
(3x + -6x) = 36 Combine like terms
-3x = 36
--------------------------------------------------------------
-3x = 36
(-3x = 36)/ -3 Division property of equality
x = -12
Step-by-step explanation:
I tried to seperate the steps so you can go through them. First you had to add on both sides to take out the like terms, then combine the 3x and the -6x to make -3x (easier to look at and divide), and finally divide to find X. the end product using X cannot be a negative because its a filler space for a real number.
