so do the product.
21h = 49*15
now divide by 21
A.35
B.2.5
C.4.2
D.6.0
(I would like a teacher from here to help me asap. I don't know what to do so an explanation would be appreciated. Thank-you.
21h = 49*15
now divide by 21
21/49 = 15/h
Cross multiplying:
21 * h = 15 * 49
Now you can solve for h by dividing both sides by 21:
h = (15 * 49) / 21
Using a calculator or long division, you will find that:
h ≈ 35.00
(rounded to the nearest hundredth)
Therefore, the correct answer is A. 35
21 * h = 49 * 15
Next, simplify the equation by multiplying the numbers:
21h = 735
Now, divide both sides of the equation by 21 to isolate the variable h:
h = 735 / 21
Calculating this division, you'll find:
h ≈ 35
Therefore, the answer is A. 35.
