The two tangent lines for each circle are the same length. Set the equations to equal and solve for x.
1. 4x + 3 = 3x +12
Subtract 3x from each side:
x +3 = 12
Subtract 3 from both sides:
x = 9
2. -2 + x = 2x -7
Subtract 2x from both sides:
-2 - x = -7
Add 2 to each side:
-x = -5
Multiply both sides by -1:
x = 5
1. In a class of x children, 16 boys. What fraction of the class are boys.
2. Inside a stable there are h horses. 6 of them are taken out of the yard to exercise. How many are left in the stable.
3. There are b people on a bus. At the next stop, 7 get off and 10 more get on. How many people are on the bus now?
6 + 9y - 18 = -3 Combine like terms (6 and -18)
9y - 12 = -3 Add 12 to both sides
9y = 9 Divide both sides by 9
y = 1
