9/10 = z/8 round to the nearest tenth

jeka57 [31]

9/10 = z/8

cross multiply

9/10(10)(8) = z/8(8)(10)

9(8) = z(10)

72 = 10z

Isolate the z, divide 10 from both sides

72/10 = 10z/10

z = 72/10

z = 7.2

7.2, or D) is your answer

hope this helps

I know it’s a lot but I need help didn’t get the material because I’m doing online classes and my WiFi is trash

g100num [7]

Answer: not sure if that is a b but i beleive it is so

bh+hr=25

move all terms to the left side and set equal to 0. then set each factor equal to zero.

h= $\frac{25}{b+r}$

isolate the variable by dividing each side by factors that dont

contain the variable.

r= $\frac{25}{h}-b$

x= $\frac{r-h}{y}$

isolate the variable by dividing each side by factors that dont

contain the variable.

h=-xy+r

solve for r by simplifieng both sides of the equation, then isolating the variable.

r=xy+h
