Answer:

39°

Step-by-step explanation:

It is the same measure as the one labeled 6x-9, since these are vertical angles.

4x +7 = 6x -9

16 = 2x . . . . . . . . add 9-4x

8 = x

4x+7 = 4(8) +7 = 39

The angle is 39°.

Answer:

Step-by-step explanation:

First, combine like terms

4x+7=6x-9

+9 +9

4x+16=-9

-16 -16

Then divide by four to isolate x

4x=-25

x=-6.25

Plug in X to get the angle measure .

Carly's family traveled 3/10 of the distance to her grandmother's house on Saturday. They traveled 3/7 of the remaining distance

polet [3.4K]

Answer:

3/10 of the total distance to her grandmother's house was traveled on Sunday

Step-by-step explanation:

Carly's family traveled distance of Saturday = $\frac{3}{10}$

Remaining distance = $1-\frac{3}{10}=\frac{7}{10}$

They traveled 3/7 of the remaining distance on Sunday.

So, Distance traveled on Sunday = $\frac{3}{7}(\frac{7}{10})$

Distance traveled on Sunday = $\frac{3}{10}$

Fraction of the total distance to her grandmother's house was traveled on Sunday = $\frac{3}{10}$

Hence 3/10 of the total distance to her grandmother's house was traveled on Sunday
