You can use it to find the area of a right triangle because a right triangle is basically a rectangle cut in half diagonally. However, this formula does not apply to all triangles because those that are not right triangles don't have a base or height, they're not really a rectangle. Because the formula for a rectangle's area is bxh, a right triangle is half of that. I hope this made sense and was helpful. :)
No, in order for this to be correct, you'd have to move BOTH decimals in the same direction the same amount of places.<span />
The answer is in the question. The question says he used 2/3 of it to make sandwiches. Unless your asking what 2/3 of 7/8 is then the answer would be 7/12.
you just multiply the top numbers together and the bottom numbers together and then reduce.

34
Step-by-step explanation:
4(8.5) = 34
Answer:
The number is -1/2.
Step-by-step explanation:
I am assuming they are fractions. So we have the equation:
5/2 x + 2/3 = -7/12
We multiply through by 12 to eliminate the fractions:
5/2 * 12 x + 2/3 * 12 = -7/12 * 12
30x + 8 = -7
30x = -15
x = -15/30
x = -1/2.
