Answer:
The value of m is 40
Step-by-step explanation:
2(m + 10) = 4(m - 15)
2m + 20 = 4m - 60
20 + 60 = 4m - 2m
80 = 2m
2m = 80
m = 80 ÷ 2
m = 40
Thus, The value of m is 40

Answer: y = 4
Step by step explanation:
−3y + 2 = −10y + 30
Step 1: Add 10y to both sides.
−3y + 2 + 10y = −10y + 30 + 10y
7y + 2 = 30
Step 2: Subtract 2 from both sides.
7y + 2 − 2 = 30 − 2
7y = 28
Step 3: Divide both sides by 7.
7y/7 = 28/7
y = 4
50 is the answer....
Percentage of 70% of what = 35?
70% × ? = 35
? =
35 ÷ 70% =
35 ÷ (70 ÷ 100) =
(100 × 35) ÷ 70 =
3,500 ÷ 70 =
50
Answer: 4 inches by 6 inches or 8 inches by 3 inches.
Step-by-step explanation:
The area of a rectangle is A = W*L
where L is the width and L is the lenght.
Now, the original rectangle has a measure of 8 in by 6 in.
if 8in is the lenght and 6 in is the width.
We want to divide only one of those measures in equal parts, such that when we take the product of the end results is equal to 24 in.
If we divide the lenght by half (so both parts will have the same width as this did not change), we now have that the lenght is 8in/2 = 4in and the width is 6in.
Now the area is 4in*6in = 24in, which is the area that we where looking for.
We also could cut the width in half, and get the dimensions 8 inches by 3 inches.
