Algebra 1 Midterm Practice

Solve for a.

• a = pw
• a = p/w
• a = w/p
• a = w + p

Solve for the indicated variable.

• A = l/w
• w = l/A
• w = A
• w = A/l

Solve for x:

• x = yb - v
• x = by - v
• x = by + v

Simplify each equation. Tell whether the equation has one, no, or infinite solutions.
3x - 8 = 3(x - 4) + 1

• one
• no solutions
• infinite solutions

14 < -2a + 6 - 2a

• a > -2
• a < -2
• a > 2
• a < 2

Solve:
6x+10>5x-12

• x>2
• x<2
• x<-22
• x>-22

Solve:
3(x - 2) < 2(x + 9)

• x<24
• x>12
• x<12
• x>24
