X=90 you have to make the two equations equal

Answer:

x=90

Step-by-step explanation:

If the two liners were parallel, <1 and <4 would be congruent because they are corresponding angles. Since they are congruent, we can set them equal to each other

<1=<4

3x-160=x+20

Solve for x, by getting x by itself

Subtract x from both sides

2x-160=20

Add 160 to both sides

2x=180

Divide both sides by 2

x=90

Slope -8 and y intercept 7

max2010maxim [7]

Answer:

The equation of Line is y = - 8x + 7

Step-by-step explanation:

Given as :

The slop of line is - 8

And The y intercept is 7

As the equation of line is y = mx + c

For y intercept , x = 0

So, With y intercept and slop ,

7 = (-8)× (0)+ c

Or, c = 7

So the equation of line is

y = mx + c

I.e y = ( - 8 ) x + 7

Hence The equation of Line is y = - 8x + 7 Answer

Decompose 3/8 as the sum of unit fractions

bearhunter [10]

Unit fractions are fractions with a 1 as the numerator(number on top)
so 3/8 equals 1/8+1/8+1/8

In your computation, approximate its value as 3.14.

andrey2020 [161]

Answer: d

Step-by-step explanation:

Find the area of the rectangle.

$A=l*w\\A=(15in)(12in)\\A=180in^2$

Find the area of the base of the semicircle.

$A=\pi r^2$

12 in would be the diameter, divide by 2 to get the radius.

$\frac{12}{2}=6$

Plug this into the formula.

$A=(3.14)(6)^2\\A=113.04in^2$

Since we do not have a full circle but a semi one instead, we must divide our result by 2.

$\frac{113.04}{2}=56.52in^2$

Add both areas.

180+56.52=236.52 $in^2$
