Answer:

x = -22/3 and y = -1

Step-by-step explanation:

First, simplify the equation 12x + 20y = -108 by dividing both sides by 4:

3x + 5y = -27

now, you can subtract the two equations:

3x + 5y = -27

- (3x - 12y = -10)

17y = -17

y = -1

plug y = -1 into the equation 3x - 12y = -10

3x - 12 *(-1) = -10

3x + 12 = -10

3x = -22

x = -22/3

w = d - 53

Because they are equal, we can take whatever is on one side of the = and replace it for what's on the other side.

d - 53 + d = 797

2d = 850

Part A and Part B , help please !
miss Akunina [59]

Part A

2:7 x 10:x

7 x 10=70 and 2 x x= 2x.

70 divided by 2 is 35, So for 10 the actual is 35 ft.

2:7 x 20:x

7 x 20= 140 and 2 x x=2x.

140 divided by 2 is 70, So for 20 the actual is 70 ft.

Part B

35 x 0.30=10.5

70 x 0.30=21

10.5+21=31.5

$31.5
