Answer:
4
Step-by-step explanation:
7h-15h+40=-72
-8h=-32
h=4
Perimeter = 9 + 13 + 6 = 28 m
area = 1/2 x 9 x 5.3 = 23.85 square m
Answer:
the number is 24
Step-by-step explanation:
10 less than two thirds the number is one fourth the number
Let the unknown number be x
two third of the number is 
10 less than two third the number becomes

one fourth the number becomes 
10 less than two thirds the number is one fourth the number

We need to solve for x
LCD is 3*4 = 12
Multiply the whole equation by 12

8x - 120 = 3x
add 120 on both sides
8x = 3x + 120
Subtract 3x on both sides
5x = 120
divide by 5 on both sides
x= 24
I think it maybe greater than becuase i looked at the y intercept and it was a two ok so then i looked for a slope of 3x but in the picture the slope is only 2x.
In order to determine the expression that should be multiplied to n^2 to get 5n^3, divide 5n^3 by n^2. First for the numerical coefficient, 5 divide 1 is 5. For the variable n, n^3/n^2 is n. Thus, the term that should be multiplied to n^2 is 5n.
