Write down the two numbers, one under the other, with the decimal points lined up.
Add zeros so the numbers have the same length.
Then subtract normally, remembering to put the decimal point in the answer.
Answer:
31
Step-by-step explanation:
Answer:
x = -3
Step-by-step explanation:
1+3x=-2(x+7)
Distribute
1+3x = -2x-14
Add 2x to each side
1+3x+2x = -2x+2x-14
1+5x = -14
Subtract 1 from each side
1-1+5x= -14-1
5x = -15
Divide each side by 5
5x/5 = -15/5
x = -3
What do you need help with?
1) In the box, we are given two points: (10,7) and (25,17.5).
2) Using these points (and the equation y2-y1/x2-x1), we know that this slope is 0.7 or 7/10.
3) y=0.7x
4) Plug 50 into the equation: y=0.7(50) = 35
Answer
35
