Solve for X, and show the equation you would use to solve.
1 answer:
Answer:
x = 20
Step-by-step explanation:
There are both consecutive interior angles and are supplementary.
The equation should be written like this:
5x + 50 + x + 10 = 180
Step 1: Simplify both sides of the equation.
5x + 50 + x + 10 = 180
(5x+x) + (50+10) = 180 (Combine Like Terms)
6x + 60 = 180
6x + 60 = 180
Step 2: Subtract 60 from both sides.
6x + 60 − 60 = 180 − 60
6x = 120
Step 3: Divide both sides by 6.
x = 20

Set up the following equations:
x represents car A's speed, and y represents car B's speed.
We'll use elimination to solve this system of equations. Multiply the first equation by 7:
Combine both equations:
Divide both sides by 28 to get x by itself:
The speed of car A is 80 mph.
Since we now know the value of one of the variables, we can plug it into the first equation:
Subtract 160 from both sides.
Divide both sides by 2 to get y by itself:
The speed of car B is 60 mph.
x represents car A's speed, and y represents car B's speed.
