Step-by-step explanation:
You have to find a number that goes into both numbers and then divide. So for example question 25:
4 goes into 4 and 8
so the answer to 25 is 1/2
4/8 = 1/2
Answer:
4/15
Step-by-step explanation:
2x/5-3y/2=7
<em>Multiply all terms by the lcd.</em>
10(2x/5) + 10(-3y/2) = 10(7)
<em>Cross cancel.</em>
2(2x)+ 5(-3y) =70
<em>Simplify.</em>
4x -15y = 70
<em>Subtract 4x from both sides.</em>
-15y = -4x +70
<em>Divide by -15 on both sides.</em>
y= 4/15x -24/3
Answer: 70 square centimeters.
Explanation: The area of a parallelogram is base times height.
Because the parallelograms are congruent, we can do 4*(3.5*5), which equals 70 square centimeters.
