Answer:

x = 20

Step-by-step explanation:

The 2 angles are vertical and congruent, thus

10x - 27 = 8x + 13 ( subtract 8x from both sides )

2x - 27 = 13 ( add 27 to both sides )

2x = 40 ( divide both sides by 2 )

x = 20

Answer:

(8x+13)=(10x-27) being vertically opposite triangles.

Now take the 8 to the next side and minus it by 10x which means 10x-8x, the answer is 2x

Then, do with 27 and 13 also and whatever the answer comes it will be divided by 2, so that is the value of x

Help plz I'm desperate

lutik1710 [3]

1st month = 18 + $\frac{3}{4}$ = 18 $\frac{3}{4}$ inches

2nd month = 18 $\frac{3}{4}$ + $\frac{3}{4}$ = 19 $\frac{1}{2}$

3rd month = 19 $\frac{1}{2}$ + $\frac{3}{4}$ = 20 $\frac{1}{4}$

4th month = 20 $\frac{1}{4}$ + $\frac{3}{4}$ = 21

5th month = 21 + $\frac{3}{4}$ = 21 $\frac{3}{4}$

<u>Grace:</u>

Because Anna is $\frac{9}{4}$ inches shorter than Grace, we can start the count from the third month:

1st month = 20 $\frac{1}{4}$

2nd month = 21

3rd month = 21 $\frac{3}{4}$

4th month = 21 $\frac{3}{4}$ + $\frac{3}{4}$ = 22 $\frac{1}{2}$

5th month = 22 $\frac{1}{2}$ + $\frac{3}{4}$ = 23
