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

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.

Write each expression using exponents x·x·x·x·y·y
Answer:
x^4*y^2
Step-by-step explanation:
Whenever you multiply a number by itself, add one to its power. X is actually x^1, but we don't write that. Keep on adding 1 to the power for every x you multiply together and do the same thing for y. You will get x^4*y^2 as the answer.
Answer:
x^4y^2
Step-by-step explanation:
because you have 4 x so you put x^4 and you have 2 y so you do y^2 which the answer is x^4y^2

Choose the inequality that represents the following graph.
Answer:
The inequality that represents the second graph is: [tex]x\leq3[/tex]
Step-by-step explanation:
From the second number line, you can see that the circle is closed on positive 3 and the arrow is pointing left - the direction of negative numbers, so you know that the value of x must be less than or equal to 3. Thus, you can write the inequality: [tex]x\leq3[/tex] - X is less than or equal to 3

Which expression is equivalent to the given expression after using the distributive property?
9(x + 3) + 15x
9 · x + 9 · 3 + 15x
9(x + 3 + 15)x
9 · x + 9 · 3 + 9 · 15x 9 · x + 3 + 15x
Answer:
the answer is b 9 · x + 9 · 3 + 15x
The expression 9(x + 3) + 15x is equivalent to the given expression.
Given,
9(x + 3) + 15x = 9 · x + 9 · 3 + 15x
9(x + 3 + 15)x = 9 · x + 9 · 3 + 9 · 15x 9 · x + 3 + 15x
We need to find which expression is equivalent to the given expression after using the distributive property.
What is distributive property?We have the distributive property of multiplication over addition and subtraction.
Example:
- distributive property of multiplication over addition
= a x ( b + c )
= a x b + a x c
- distributive property of multiplication over addition and subtraction.
= a x ( b - c )
= a x b - a x c
Find the expression using the distributive property.
We have,
- 9(x + 3) + 15x
= 9 · x + 9 · 3 + 15x
This is equivalent to 9 · x + 9 · 3 + 15x
- 9(x + 3 + 15)x
= ( 9 · x + 9 · 3 + 9 · 15 ) x
= 9 . x . x + 9 . 3 . x + 9 . 15 . x
This is not equivalent to 9 · x + 9 · 3 + 9 · 15x 9 · x + 3 + 15x
Thus the expression 9(x + 3) + 15x is equivalent to the given expression.

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
Make "t" the subject of the formula s=2t+5.
Answer:
t = [tex]\frac{s-5}{2}[/tex]
Step-by-step explanation:

s = 2t + 5 ( subtract 5 from both sides )
s - 5 = 2t ( divide both sides by 2 )
[tex]\frac{s-5}{2}[/tex] = t
The length of a rectangle is twice the width. The area of the rectangle is 96 square units. Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square? Estimate the length and width of the rectangle.
Answer:
The estimate part is D or the square root of 48 and the rectangle is 13.8 units long and 6.9 units wide. Have Fun on Savvas Bro
Step-by-step explanation:
The required answer is,
Width of the rectangle = 6.325 units
Length of the rectangle = 12.65 units
Side length of the square the 6.325 units.
What is rectangle?A plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.
Now it is given that,
The length of a rectangle is twice the width. The area of the rectangle is 96 square units.
The area of the rectangle = Length × Width
Length = 2W
96 square units = 2W × W
96 = 2W²
W² = 96/2
W² = 48
W = √48
Width of the rectangle = 6.928203 units
Approximately = 6.928 units
Now,
Length = 2 × Width
= 2 × 6.928
= 13.86 units
• Now,we need to divide the rectangle into two squares with equal area, and estimate the side length of each square,
When we divide a rectangle into 2 squares,
The length is divided into two.
Hence, the length of the rectangle = 13.86 units
13.86 units ÷ 2 = 6.928 units.
Hence, the side length of the square the 6.928 units.

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

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.

The path of a rotation is defined by a
Axis
Step-by-step explanation:
A rotation is a circular movement of an object around a center (or point) of rotation. A three-dimensional object can always be rotated about an infinite number of imaginary lines called rotation axes . If the axis passes through the body's center of mass, the body is said to rotate upon itself, or spin. A rotation around an external point, e.g. the planet Earth around the Sun, is called a revolution or orbital revolution, typically when it is produced by gravity. The axis is called a pole.

10 POINTTSSS answer fast The formula a = m − n represents the actual cost, a, of an item with original price m after a coupon for n dollars off is applied. Solve the formula for the amount of the coupon. Group of answer choices n=m−a n = a − m n = −m − a n=a+m
Answer:
n = m - a
Step-by-step explanation:
Given:
a = m − n
Where,
Actual cost of the item = a
Original price of the item = m
Amount of Coupon = n
Solve the formula for the amount of the coupon
Making n the subject
a = m − n
Subtract m from both sides
a - m = m - n - m
a - m = - n
Divide both sides by -1
(a - m) / -1 = -n / -1
- a + m = n
Can also be written as
n = m - a
