nikklg [1K]

Answer:

51.2

Step-by-step explanation:

$\frac{15}{5} = \frac{25}{x}$

15x = 120

x = 8

so now we know that 2 sides of the bigger triangle are 24 and 8

now

$\frac{8}{x} = \frac{5}{12}$

96 = 5x

x = 19.2

19.2 + 24 + 8

Somebody please help me on multiple step equations with parenthesis.

mash [69]

Answer:

k = 8

Step-by-step explanation:

8(10 - k) = 2k

First, distribute within the parenthesis,

80 - 8k = 2k

Add 8k to both sides of the equation

80 = 10k

Divide both sides by 10 to get your answer

8 = k

I hope this helps :)

Eighty percent of seniors at the local high school graduate each year. If there are 750 seniors this year, how many will graduat

yulyashka [42]

What you need to find is 80% of 750

There are many ways to figure that out but the way that I did it is to divide 750 by 100. The answer (7.5). Is 1% of 750
In all I had to do was multiply 7.5 x 80. Giving us the answer which is 600
