Answer:
6(4+x)
Step-by-step explanation:
Answer:
6(x+4)
Step-by-step explanation:
We want to write an algebraic expression for "six times the sum of four and a number"
Let's break this down.
The sum of four and a number:
The words "sum" indicates addition. We can call " a number" x, since it is unknown.
So, the sum of four and a number is: (x+4).
Six times:
The word "times indicates multiplication. We are multiplying six and the sum of four and a number.
So, we have: 6(x+4)
The algebra expression for "six times the sum of four and a number" is 6(x+4)
I need help with this problem 2•1/2+4(4•2-7)
Answer:
5
Step-by-step explanation:
2×1/2 + 4×(4×2 - 7) = ⇒ multiplication1 + 4×(8 - 7) = ⇒ parenthesis1 + 4×1 = ⇒ multiplication1 + 4 = ⇒ addition5 ⇒ answer— 7х – 10 = 18 + 3x
Solve the equation
Answer:
-2.8 = x
Step-by-step explanation:
-7х – 10 = 18 + 3x
+7x. +7x
-10. = 18+ 10x
-18. -18
-28. = 10x
/10. /10
-2.8 = x
A satellite's speed is
10,000 m/s. After 1
minute, it is 5,000 m/s.
What is the satellite's
acceleration?
Answer:
-83.33 [tex]m/s^2[/tex]
Step-by-step explanation:
Given that:
Initial speed of satellite = 10,000 m/s
Final speed of satellite = 5,000 m/s
Time taken = 1 minute
Let us convert it into seconds.
Time taken = 1 minute = 60 seconds
Let us have a look at the formula:
[tex]v=u+at[/tex]
where [tex]v[/tex] is the final speed
[tex]u[/tex] is the initial speed,
[tex]t[/tex] is the time taken and
[tex]a[/tex] is the acceleration
[tex]5000=10000+a\times 60\\\Rightarrow 60a = 5000-10000\\\Rightarrow 60a = -5000\\\Rightarrow a = -\dfrac{5000}{60}\\\Rightarrow \bold{a = -83.33\ m/s^2}[/tex]
Negative sign indicates that the satellite is in slowing down motion i.e. its speed is decreasing.
So, the answer is:
-83.33 [tex]m/s^2[/tex]

The table below shows the amount of money Sarah spends for a craft demonstration. Number of People Attending Cost 5 $15 8 $18 10 $20 15 $25 Sarah spends a total of $60. Based on the information in the table, how many people attended the craft demonstration? 20 30 50 70
Answer:
Nobody who paid $18 attended, because that can't be part of $60.
Step-by-step explanation:
4 at $15
10 at $20
15 at $25
=
29 people.
There are 30 people was attended the craft demonstration.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
We have been given that number of people attending at respective costs as 5 at $15, 8 at $18, 10 at $20, 15 at $25
Since Sarah spends a total of $60.
As per the condition,
So the number of people who attended the craft demonstration attending at respective costs would be 5 at $15, 10 at $20, and 15 at $25
⇒ 5 + 10 + 15 = 30
Thus, the required number of people would be 30 because $18 can't be included in $60, anyone who paid that amount attended.
Therefore, there are 30 people was attended the craft demonstration.

-12 = 2 + 5y + 2y
Can you me do the work
Answer:
-2 =y
Step-by-step explanation:
-12 = 2 + 5y + 2y
Combine like terms
-12 =2+7y
Subtract 2 from each side
-12-2 = 2+7y-2
-14 = 7y
Divide each side by 7
-14/7 = 7y/7
-2 =y
Does this equation has one solution, no solution, or infinitely many solutions? 2(x + 2) =2x - 8 Question
Answer:
no solution
Step-by-step explanation:
2(x + 2) = 2x -8
2x+4 = 2x-8
2x - 2x =-8 - 4
0 = -12

A running shoe manufacturer has a fixed overhead of $ 580000.00, variable costs of $ 50.00, and a selling price of $ 100.00.
(c) Smallest number of pairs of shoes the company must sell to turn a profit:
(d) Total profit
Answer:
To make a profit the company must sell 11601 units.
Step-by-step explanation:
Giving the following information:
Fixed costs=$580,000
Unitary variable costs= $50
Unitary selling price= $100
First, we need to calculate the break-even point in units:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 580,000 / (100 - 50)
Break-even point in units= 11,600 units
To make a profit the company must sell 11601 units.
In order to determine the total profit, you need to use the following formula:
Total profit= 50*x - 580,000
x= units sold
For example:
x= 15,000
Total profit= 50*15,000 - 580,000
Total profit= $170,000
what is the21st term of -3,2,7
Answer:
102
Step-by-step explanation:
The first step is to find out how to find the next number in the term.
In this we can see that to get to the next number in the term we need to add 5.
The easiest way to figure out the 21st term of this, would be to multiply 5×21. This is equal to 105.
But since we started at three less than 5, we need to subtract 3 from 105. 105-3=102.
The 21st term is 102.

In right triangle ABC, A = 42°. Find the measure of B which is the other non
right angle.
A=42
C=90
B=48
We can reason that C will be equal to 90 since it is the right angle. So to find B we have to subtract 90 from 180 to get 90 then subtract 42 to get 48
B=48 degrees
What is the solution to the situation below? The sum of three consecutive integers is 42
Answer:
13,14,15
Step-by-step explanation:
let the first number be n
The next 2 consecutive numbers will be
n+1 and n+2
Sum of these numbers is 42
n+ n+1+n+2=42
Combine like terms
3n+3=42
3n=42-3=39
n=39/3=13
So the numbers are
n=13
n+1=13+1=14
n+2=13+2=15

Step-by-step explanation:
Point O is on line segment NP. Given OP = 10, NP = 2x, and NO = x +7,
determine the numerical length of NO.
Answer: NO =
Answer:
Given : NP is a line segment
and O is the mid point
therefore, we can write
NP = NO + OP
now put the values
under NP write 2x , NO = x+7 , OP = 10
Therefore the equation that comes to us after putting values is
2x = x+7 + 10
now solving
2x - x = 7+10
x = 17
therefore
numerical length of NO = x+7
i.e. , 17 + 7 = 24
