In each of the problems, one of the equations is solved for y. Just plug in what y is equal to into the other equation.
1.) Plug -3 in for y.
-3 = 7x - 10
7x = 7
x = 1
2.) Plug -8 in for y.
-8 = -2x - 12
-2x = 4
x = -2
9.) Plug -8x in for y.
2x + 4(-8x) = 0
2x - 32x = 0
-30x = 0
x = 0
10.) Plug 2x in for y.
6x + 7(2x) = 20
6x + 14x = 20
20x = 20
x = 1
Hey Jasmine! So a linear pair must equal 180 degrees, Option A makes the most sense to me because if you were to combine both the angles together they would equal 180 degrees, all of the other options would be skewed from 180
8*2.89=23.12$
16*1.39=22.24$
23.12+22.24=45.36$
It’s 45.36$
Answer:
2 2/3 foot
Step-by-step explanation:
3x=8
x=8÷3
=2 2/3 foot
Add the ratio together: 5:4 becomes 5+4 = 9
divide the amount by 9:
54 / 9 = 6
multiply 6 by both 5 and 4
6 *5 = 30
6 * 4 = 24
30 and 24 are two amounts
