If l is parallel to m, solve for x and y.

adelina 88 [10]

Answer:

x=17, y=9

Step-by-step explanation:

(5x - 38)° = (3x - 4)°

2x = 34

x=17

(5(17)-38))=47

90°+47°+(7y-20)=180°

7y-20=43°

y=9

Maureen walked 3 miles how many feet did she walk

Ostrovityanka [42]

Answer:

15,840 feet.

Step-by-step explanation:

We have been given that Maureen walked 3 miles. We are asked to convert the distance walked by Maureen in feet.

Since we know that 1 mile equals 5,280 feet, so to convert our given distance we will multiply 3 by 5,280.

$\text{Number of feet Maureen walked}=\text{3 miles}\times \frac{5,280\text{ feet}}{\text{Mile}}$

$\text{Number of feet Maureen walked}=3\times 5,280\text{ feet}$

$\text{Number of feet Maureen walked}=15,840\text{ feet}$

Therefore, Maureen walked 15,840 feet.

What is 2/3x + 1/6 = 4/3x

e-lub [12.9K]

First you have to get the variable to one side.
To do this you have to subtract 2/3x from both sides.
4/3x-2/3x=2/3x
Now you have:
1/6=2/3x
Divide by 2/3
1/6÷2/3=1/6×3/2=3/12=1/4
Your answer is:
X=1/4
