2x - 10 = 10 - 3x
Simplifying
2x + -10 = 10 + -3x
Reorder the terms:
-10 + 2x = 10 + -3x
Solving
-10 + 2x = 10 + -3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3x' to each side of the equation.
-10 + 2x + 3x = 10 + -3x + 3x
Combine like terms: 2x + 3x = 5x
-10 + 5x = 10 + -3x + 3x
Combine like terms: -3x + 3x = 0
-10 + 5x = 10 + 0
-10 + 5x = 10
Add '10' to each side of the equation.
-10 + 10 + 5x = 10 + 10
Combine like terms: -10 + 10 = 0
0 + 5x = 10 + 10
5x = 10 + 10
Combine like terms: 10 + 10 = 20
5x = 20
Divide each side by '5'.
x = 4
Simplifying
x = 4
Answer:
top left choice
Step-by-step explanation:
A car going at a higher speed than a second car will travel more distance in the same amount of time.
Look at the graph. For example, imagine that each grid line on the x-axis is 1 hour. Look at the 5th grid line to the right of the origin. That would mean 5 hours into the trips.
Now imagine that each grid line on the y-axis is 10 miles.
For the low speed car, at 5 hours, it traveled 40 miles.
For the high speed car, it traveled 70 miles in the same 5 hours.
That makes the x-axis the independent variable representing time, and the y-axis the dependent variable representing position.

Answer:
BC ≈ 9.6 mi
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationships between sides and angles in a right triangle.
Tan = Opposite/Adjacent
tan(58°) = BC/(6 mi)
BC = (6 mi)tan(58°)
BC ≈ 9.6 mi
