Answer:
24
Step-by-step explanation:
Let 12x represent the original number.
One fourth of that number can be represented by 3x, and one third of the number can be represented by 4x.
Create an equation that sets this equal to 38, and solve for x:
12x + 3x + 4x = 38
19x = 38
x = 2
The original number is represented by 12x, so plug in 2 as x:
12(2)
= 24
So, the original number is 24.
Answer:
Two sides have a measure of 48 cm and the shortest side is 16 cm.
Step-by-step explanation:
this is an isosceles triangle
let x = length of shortest side
let 3x = length of other two sides
find x:
3x + 3x + x = 112
7x = 112
x = 16
3x = 48
The answer is C) Step 3
Li forgot to multiply the two negatives in order to get positive 3/10. The answer should not be negative.
The right steps are:
-4/5 / 8/-3
Flip the second part to multiply:
-4/5 * -3/8
Multiply:
12/40
Simplify:
3/10
I hope this helps!
