37 = −3 + 5(x + 6) multi step equation step by step pls
Answer:
x = 2
Step-by-step explanation:
37 = -3 + 5(x+6)
37 + 3 = 5*x + 5*6
40 = 5x + 30
40 - 30 = 5x
10 = 5x
x = 10/5
x = 2
Check:
37 = -3 + 5(2+6)
37 = -3 + 5*8
37 = 40 - 3

Tanya bought three adult tickets and one children's ticket to a movie for 24.60 Li bought five adult tickets and four children's tickets for 50.10 . Find the cost of one adult ticket and the cost of one children's ticket.
Answer:
adult tickets 6.9
children tickets 3.9
Step-by-step explanation:
3x + y = 24.60 L1
5x + 4y = 50.10 L2
5L1 - 3L2
15x + 5y = 123
-15x - 12y = -150.3
-7y = -27,3
y = -27,3/-7
y = 3.9
3x + y = 24.60
3x + 3.9 = 24.60
3x = 24.60 - 3.9
3x = 20.7
x = 20.7 / 3
x = 6.9
In a simple frequency distribution, to determine _______________, we divide the observed range by the number of intervals.
Answer:
Interval width
Step-by-step explanation:
In normal statistics, we calculate range as difference between Maximum Value and Minimum Value of the data given.
However, in group simple frequency distribution, we have what we call interval width which is simply the range of values contained in each interval.
To determine this interval width, we we divide the observed range by the number of intervals chosen.

Make "t" the subject of the formula s=2t+5.
Answer:
t = [tex]\frac{s-5}{2}[/tex]
Step-by-step explanation:
Given
s = 2t + 5 ( subtract 5 from both sides )
s - 5 = 2t ( divide both sides by 2 )
[tex]\frac{s-5}{2}[/tex] = t
Convert 32% to a fraction. Make sure your answer is fully reduced.
Answer:
8/25
Step-by-step explanation:
32/100
Find what value can divide the numerator's value (32) and the denominator's value (100) into a whole number, for this problem, 4 is the value that can do this.
32/4= 8
100/4= 25
8/25
FACTOR !!!
a) 5x^2+25
b) 2x^2-3x-2
Step-by-step explanation:
(a): 5x^2 + 25 = 5 * x^2 + 5 * 5 = 5(x^2 + 5).
(b): 2x^2 - 3x - 2 = 2x^2 - 4x + x - 2
= 2x(x - 2) + 1(x - 2) = (2x + 1)(x - 2).
16. The quotient of a number and -2 is the same as the sum of -4 and 10.
Answer: The number is -12
Step-by-step explanation:
The situation can be represent by the equation
[tex]\frac{n}{-2} = -4 + 10[/tex] Now solve for n by combining like terms on the right side
[tex]\frac{n}{-2}[/tex] = 6 multiply both sides by -2
n = -12
The measure of an angle is 149°. What is the measure of its supplementary angle?
Answer: 31°
Step-by-step explanation:
Supplementary angles add up to 180 degrees so add 149 degrees to a number of degrees to get 180 degrees.That can be represent by the equation,
149 + x = 180 where x is the supplement so solve for x
-149 -149
x = 31

HELP Drag and drop the tiles with the coordinate points, so they match up with an equation that they satisfy (0,5) y = 13x + 5 y=-3x y = x - 10 (0,0) (8,-2) (-2,-21) (-5, -15) (-39)
Answer:
Step-by-step explanation:
1. y = 13x + 5
y = 13(0) + 5
y = 0 + 5
y = 5
(0,5)
y = 13(-2) + 5
y = -26 + 5
y = -21
(-2, -21)
2. y = -3x
y = -3(-3)
y = 9
y = -3(0)
y = 0
(0,0)
(-3,9)
3. y = x - 10
y = -5 - 10
y = -15
(-5, -15)
y = 8 - 10
y = -2
(8, -2)
The correct options are:
1. y = 13x + 5 ⇒ (0,5)
2. y = -3x ⇒ (0,0)
3. y = x - 10 ⇒ (8, -2)

what is greather than -7
what is less than -2
Answer:
The greater than of -7 is 7. The less than -2 is 2.
Step-by-step explanation:
It's the same distance from both but, the positive number always been greater than negative number.

Solve 5 (r +9) – 2 (1 - r) = 1.
The solution is r= ????
Step-by-step explanation:
5(r + 9) - 2(1 - r) = 1
5r + 45 - 2 + 2r = 1
7r + 43 = 1
7r = -42
r = -6.
Answer:
r = -6
Step-by-step explanation:
Given equation,
→ 5(r + 9) - 2(1 - r) = 1
Now the value of r will be,
→ 5(r + 9) - 2(1 - r) = 1
→ 5r + 45 - 2 + 2r = 1
→ 5r + 2r + 43 = 1
→ 7r = 1 - 43
→ 7r = -42
→ r = -42/7
→ [ r = -6 ]
Hence, the value of r is -6.

3p + 7 = -4(4 - 6p) + 2
p=1
Step-by-step explanation:
[tex]3p + 7 = - 4(4 - 6p) + 2 \\ 3p + 7 = - 16 + 24p + 2 \\ 3p - 24p = - 16 + 2 - 7 \\ - 21p = - 21[/tex]
[tex] \frac{ - 21p}{ - 21} = \frac{ - 21}{ - 21} \\ p = 1[/tex]
Answer:
p = 1
Step-by-step explanation:
Given
3p + 7 = - 4(4 - 6p) + 2 ← distribute and simplify right side
3p + 7 = - 16 + 24p + 2
3p + 7 = 24p - 14 ( subtract 3p from both sides )
7 = 21p - 14 ( add 14 to both sides )
21 = 21p ( divide both sides by 21 )
1 = p , that is p = 1
