Answer:

G. \frac{3.2}{2} = \frac{a}{8}

Step-by-step explanation:

Given that figure I and figure II are similar, it follows that the ratio of their corresponding side lengths are equal and the same.

Thus:

\frac{3.2}{2} = \frac{a}{8} = \frac{8}{5} = \frac{6.4}{b}

Therefore, the proportion that must be true is:

✔️\frac{3.2}{2} = \frac{a}{8}

Simplify the equation -4d - 37 = 7d + 18
exis [7]

Answer:

d=-5

Step-by-step explanation:

-4d-37=7d +18

move the terms to its correct side

-4d-7d=18+37

calculate the like terms together.

-11d=55

divide both sides by -11. both of the negavtive (-11) will cancel out and become d on the left and on the right 55 will be divided by -11 = -5. the 5 is negative because there's a negative -11 if there were a postive 11 it will be 5 instead of D=-5
