What value of w makes the equation 145 = w + 27 true?

Answers

Answer:

118

Step-by-step explanation:

In the equation 145 = w + 27, you can solve for w by subtracting 27 from 145. That would give you 118. You can check this is correct by adding 27 to 118. 118 plus 27 = 145.

Answer:

118

Step-by-step explanation:

145 = w + 27

Switch the + sign before the 27 and switch into a minus and move it to the other side.

145-27=w

145-27=118

w=118

The graph of the equation is attached .

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

The slope-intercept form of the line equation

y= mx + c

where m is the slope

b is the y-intercept

We are Given that the profit y (in dollars) for a business from selling x coats is represented by the equation

y=47x .

Now comparing with the slope-intercept form of the line equation;

m = 47

We know that the value of the y-intercept can be determined by setting x = 0

substitute x = 0 in the equation

y = 47(0)

y = 0

Thus, the y-intercept b = 1

Thus,

The slope m = 47

The y-intercept b = 1

The graph of the equation is also attached.

(1,47) (2,94) (3,141)

Hence, the line passes through the origin with the y-intercept 0.

B. 10n + 2
C. n² + 5

3(x-4)=5(x+2)

Answers

Answer:

x = -11

Step-by-step explanation:

1. Distribute 3 to the parenthesis and distribute 5 to the parenthesis

3x-12 = 5x + 10

2. Combine like terms (subtract 3x on both sides and then subtract 10 on both sides)

2x = -22

3. Divide both sides by 2

x = -11

please give me brainliest if this helped

Answer:

x=−11

Step-by-step explanation:

3(x-4)=5(x+2)

Simplify both sides of the equation:

3(x−4)=5(x+2)

(3)(x)+(3)(−4)=(5)(x)+(5)(2)(Distribute)

3x−12=5x+10

Subtract 5x from both sides

−2x−12=10

add 12 to both sides

−2x=22

Divide by -2 both sides

x=−11

−15x−40=23−8x
What does x =

Answers

Answer:

x = -9

Step-by-step explanation:

-15x - 40 = 23 - 8x

Add 8x to both sides

-15x + 8x - 40 = 23

-7x - 40 = 23

Add 40 to both sides

- 7x = 23 + 40

-7x = 63

Divide both sides by (-7)

x = 63/-7

x = -9

Answer:

x = -9

Step-by-step explanation:

-15x - 40 = 23 - 8x

add 8x to both sides to bring -8x to the left side

-15x + 8x - 40 = 23

add 40 to both sides to bring -40 to the right side

-15x + 8x = 23 + 40

add the common terms

-7x = 63

for x to be alone divide -7 to both sides

x = -9

Explain how you can find the volume of the figure below. Then, solve- what is the volume of the figure? Make sure to include your units

Answers

Answer: a) The figure can be reasonably divided into two geometries:

• a rectangular prism

• a hemisphere.

b) The volume of the rectangular prism is given by

V = lwh

V = (10 cm)(5 cm)(4 cm) = 200 cm³

The volume of the hemisphere is given by

V = (2π/3)r³

V = (2π/3)(3 cm)³ = 18π cm³

c) The total volume of the figure is

total volume = (prism volume) + (hemisphere volume)

V = 200 cm³ + 18π cm³

V ≈ 256.549 cm³
