Answer:
2
Step-by-step explanation:
4y = 2x + 8
First get the equation in slope intercept form y= mx+b where m is the slope and b is the y intercept
Divide each side by 4
4y/4 = 2x/4 +8/4
y = 1/2x +2
The slope is 1/2 and the y intercept is 2
So basically, the answer is 21 because 4 goes into 8, 2 times then you subtract 8-8, you'll get 0, bring down the four, 4 goes into, 1 time, subtract 4-4 and it equals 0, so you should get 21
Move variable to left hand side and change its sign, divide both side of the equation by 0.504
Answer:
Step-by-step explanation:
Its the fourth choice, 8000 is closer to 8132 so you would round that down instead of choosing 8500. Also, 8000 ÷ 20 = 400
10 times as large since 80 x 10 is 800
