What is the height of a triangle with a base of 6 yards and an area of 72 square yards?
ANEK [815]

Answer:

24

Step-by-step explanation:

the height of a triangle is A=(b·h)÷2

We know the area and base so replace: 72=(6×h)÷2

Solve:

72=(6×h)÷2

·2         ·2

144=6h

÷6   ÷6

h=24

24 yards

Use parenthesis to make each number sentence true. <br><br> 124 - 6 x 0 + 15 = 34
Natasha2012 [34]

Answer:

12 - 6 x (0 + 15) = 34

How I got my answer

First, how i got my answer was that I had to solve the equation first, ignoring the answer. I got 0 x 6 = 0, then I did 124 - 0 = 124, then I did 124 - 15 = 109, which clearly isn't 34. I figured that we have to put the parentheses around the zero because if we don't, we are going have to multiply something by zero, which always gets zero. After that, I decided that I should put the parentheses around either the 6, or the 15. I did both, and saw which one was correct. If we put it around the 6, we get, 124 - (6 x 0) + 15 = 124 - 0 - 15 = 124 - 15 = 109, which isn't 34. Then I checked 124 - 6 x (0 + 15) = 124 - 6 x 15 = 124 - 90 = 34, and we just got the answer.

P.S. Sorry if it was confusing, I didn't really know how to explain it
