Answer:

27.5 miles

Step-by-step explanation:

Set up a proportion: $\frac{412.5}{15} = \frac{x}{1}$
Cross multiply, then divide: 412.5 × 1 = 412.5, 412.5 ÷ 15 = 27.5
So, Carla's car can travel 27.5 miles on 1 gallon of gas

I hope this helps!

Answer:

x = 3°

Step-by-step explanation:

<u>S and T are supplementary angles</u>

m∠S + m∠T = 180°
105° + 24x + 3° = 180°
24x = 180° - 108°
24x = 72°
x = 72°/24
x = 3°

Which of the following lines are perpendicular to 3x-2y+7=0

aniked [119]

The line 2x + 3y - 5 = 0 is perpendicular to the line 3x - 2y + 7 = 0

Step-by-step explanation:

If the two lines are perpendicular, then the product of their slopes is -1

1. The general form of the linear equation is Ax + By + C = 0, where

A , B and C are integers

2. The slope of the line is $m=\frac{-A}{B}$

∵ The equation is 3x - 2y + 7 = 0

∴ A = 3 and B = -2

∴ The slope of the line is $m=\frac{-3}{-2}$

∴ The slope of the line is $m=\frac{3}{2}$

Let us find the slopes of the given equation to find which of them

perpendicular to the line above

∵ 2x + 3y - 5 = 0

∴ A = 2 , B = 3

∴ The slope of the line is $m=\frac{-2}{3}$

∵ $\frac{3}{2}$ × $\frac{-2}{3}$ = -1

∴ The line 2x + 3y - 5 = 0 is perpendicular to the line 3x - 2y + 7 = 0

∵ 3x + 2y - 8 = 0

∴ A = 3 , B = 2

∴ The slope of the line is $m=\frac{-3}{2}$

∵ $\frac{3}{2}$ × $\frac{-3}{2}$ ≠ -1

∴ The line 3x + 2y - 8 = 0 is not perpendicular to the line 3x - 2y + 7 = 0

∵ 2x - 3y + 6 = 0

∴ A = 2 and B = -3

∴ The slope of the line is $m=\frac{-2}{-3}$

∴ $m=\frac{2}{3}$

∵ $\frac{3}{2}$ × $\frac{2}{3}$ ≠ -1

∴ The line 2x - 3y + 6 = 0 is not perpendicular to the line 3x - 2y + 7 = 0

The line 2x + 3y - 5 = 0 is perpendicular to the line 3x - 2y + 7 = 0

Got an easy one for you guys

Oduvanchick [21]

Answer:

x=17

Step-by-step explanation:

The exterior angle theorem states that one exterior angle of a triangle is equal to the sum of its opposite interior angles. Knowing this, we can set up the following equation:

(8x-11)=(5x)+(2x+6)

Open up the parentheses

8x-11=5x+2x+6

8x-11=7x+6

Add 11 to both sides

8x-11+11=7x+6+11

8x=7x+17

Subtract both sides by 7x

8x-7x=7x+17-7x

x=17

I hope this helps!
