So, let's make these two values improper fractions so they're easier to work with. $4+\frac{1}{3}=\frac{12}{3}+\frac{1}{3}=\frac{13}{3} 3+\frac{1}{2}=\frac{6}{2}+\frac{1}{2}=\frac{7}{2}$

So, to get the rate he grew in those months we have:

$\frac{\frac{13}{3} \text{inches}}{\frac{7}{2}\text{months}} =\frac{26\text{inches}}{21\text{months}}$

And to get the rate he grew in one month we have to divide both our numerator and our denominator by 21 to get:

$\frac{\frac{26}{21} \text{inches}}{\text{month}}\approx \frac{1.24\text{inches}}{\text{month}}$ aka he grew 1.24 inches in a month.

Find the value of x and y

tankabanditka [31]

Answer:

x = 3, y = 10.

Step-by-step explanation:

The 2 triangles are similar so the corresponding sides are in the same ratio.

x/6 = 4/8

x/6 = 1/2

x = 6/2 = 3.

y/5 = 8/4 = 2

y = 5*2 = 10,
