How to find variables x- and y-
Monica [59]

It says that the triangles are congruent (same size). Also, a triangle's angles add up to 180 degrees. In both of these triangles, one angle is 90° and another angle is 52°. The other angle is 180°-90°-52°=38°.

Solve these equations to find x and y: 2x+18=38, 3y+11=38

2x+18=38\\2x=20\\x=10

3y+11=38\\3y=27\\y=9

Komok [63]

Answer: 3 min

Step-by-step explanation:

Step 1. Find the constant speed

you walked 1000 feet in 15 min

1000 ft/ 15min=200/3 ft / min

Step 2. Apply the constant speed to the left distance

You already walked 1000 feet and it is total 1200 feet

1200-1000=200 feet left

distance ÷ speed=time

200 ÷ (200/3)=3 min

Bill ate 1/4 pound of trail mix on his first break during a hiking trip. On his second break, he ate 1/6 pound. How many pounds
tino4ka555 [31]
Since we know that he ate 1/4 pound one time, and 1/6 another time, we have to add up the fractions. 

1/4+1/6

LCM of 4 and 6 = 12

3/12 + 2/12 

Add the numerators: 

5/12

So, he ate 5/12 of a pound of bars in both breaks. 

Hope this helps!
