x = 5

Step-by-step explanation:

I wasn't sure if you needed just x or if you needed the other angles so I did both.

Answer:

x=5

Step-by-step explanation:

the angle is put in there to throw you off.

Each side is parallel. so each side is equal, it's a parallelogram.

So:

x + 2 = 2x - 3

x + 2 + 3 = 2x

x + 5 = 2x

x - 1x + 5 = 2x - 1x

5 = x

Hope this helps. If it's the best mark brainlyiest.

If not no problem.

A portion of a map with cities a and b is shown.The map uses a scale of 1 inch to 30 miles. A new map has a scale of 2 inches=15

Alina [70]

Answer:

22.5miles

Step-by-step explanation:

For Map 1;

1 inches = 30miles

For Map 2:

2 inches = 15miles

1 inches = x

2x = 1 *15

x = 15/2

x = 7.5miles

This means that 1 inch represents 7.5miles on Map 2'

The distance between the two cities in miles = 30miles - 7.5miles

The distance between the two cities (in miles) = 22.5miles

In a volcano, erupting lava flows continuously through a tube system about 20 kilometers to the sea. Assume a lava flow of 0.5 k

butalik [34]

Answer:

40 hours

Step-by-step explanation:

Lets take "x" as the # of hours it takes the lava to reach the sea

since there is a lava flow of 0.5 kilos per hour

we will multiply "x" with 0.5

0.5x

now the tube system is 20 kilometers long

this means that at a rate of 0.5 kilos per hour the lava will reach the sea once it is 20 kilometers deep

0.5x=20

divide "0.5" by both sides to eliminate the coefficient

$\frac{0.5x}{0.5} =\frac{20}{0.5}$

x=40

it will take 40 hours for the lava to reach the sea

Hope this helps!
