Answer:
B
I
Step-by-step explanation:
A triangle's angles must add up to 180
68+90+x=180
158+x=180
22=x
3 and 2 must add up to 180
70+x=180
angle 2= 110
angle 2 and angle 1 have to add up to 180 as well
110+x=180
andgle 1= 70
$61 x 3= $183
$183 x .08225= 15.11
$183 + 15.11= $198.11
Answer:
Step-by-step explanation:
Subtract 4 times the first equation from the second:
(-7y +16x -80) -4(-9y +4x -20) = (0) -4(0)
29y = 0 . . . . . simplify
y = 0 . . . . . . . .divide by 29
4x -20 = 0 . . . . substitute 0 for y in the first equation
x -5 = 0 . . . . . .divide by 4
x = 5 . . . . . . . . add 5
The solution to this system is (x, y) = (5, 0).
Since 200 is a constant, of x, move 200 out of the integral. 200x+c. Constant is a fixed value that does not change.

For example let's say Megan has to pay the cab driver $50. Here's the equation 50=1.50x + 5
First you want to get x by itself on one side. So subtract 5 on both sides
50=1.50x + 5
-5 -5
---------------------------
45=1.50x
Now that you have x on one side; however, you want to divide to get the answer.
45=1.50x
-----------------------
1.50
x = 30
So if Megan pay $50 that mean she rode 30 miles
