Step-by-step explanation:
first you have to find the value of X. So you take both expressions and make them equal to 180 degrees. Then you solve for X. Once you do that X should equal 30. Then in place of X plug in 30 and solve. it should look like this (3(30)+22). The answer is 112 degrees.
You could of also looked at your angle and saw it was an obtuse angle. The only answer that was obtuse was 112 degrees.

Answer choice A
8 x 2.54=20.32
15x=45
45/15 =3
X=3
45 miles in 3 hours
How long did it take for 40 miles?
15x=40
40/15 = 2.6666667
15 x 2= 30
15 x 2.5 = 37.5
15 x 2.6 = 39
15 x 2.7 = 40.5
1 hour equals 60 mins
Answer:
It took Cole about 2 hours and 6 mins to ride 40 miles.
Answer:
11
Step-by-step explanation:
5(2+4)-(2+3^3)
=5(8)-(2+27)
=40-29
=11
A) <span>3x + </span><span>2.5y= 27
B) 5x – 2.5y = 5
</span>Adding A and B we get
8x = 32
x = 4
A) 3*4 + <span>2.5y= 27
</span>A) 12 + <span>2.5y= 27
</span>A) <span>2.5y= 15
y = 6
