How old am I?
25
Solve: 0.05w = 1.4
w=25
Solve: -2x = 3x + 10
x=-2
Solve: |x - 4| = 10
x = 14 or x = -6
A=bh, solve for b
b= A/h
Where did I go to college?
UMaine
What does it mean for an equation to have no solution?
False statement
Solve: 0.5(6h - 4) = -5h + 1
h=0.5
Solve: |2x + 3| = 9
x = 3 or x = -6
Rewrite: 3y - x = 9, solve for y
y = (x+9)/3
How many siblings to I have?
One, older sister
Solve: 17 = 7 + 4(2.2d - 8.5)
d=5
What does it mean if an equation has infinitely many solutions?

Solve: 5(3 - x) + 2(3 - x) = 14
x=1
Solve: 3(2a - 2) = 2(3a - 3)
No Solution
|x-3|+4=10
x=9 or x=-3
Rewrite C = 5/9(F - 32) to solve for F
F = 9/5C + 32
What is my astrological sign?
