Variables and Expression
Give two ways to write each algebraic expression in words.
1. n-5 = A number minus five, or the difference between a number and five.
2. t+12= A number plus twelve, or a number increased by twelve.
3. 8x= A number times eight, or a number multiplied by eight.

Solving Equations by Adding or Subtracting
1. s-5=3. s is equal to 8 because 8-5=3
2. 17=w-4. w is equal to 21 because 21-17=4
3. k-8=-7. k is equal to -15 because -15 -8=7
1. s-5=3. s is equal to 8 because 8-5=3
2. 17=w-4. w is equal to 21 because 21-17=4
3. k-8=-7. k is equal to -15 because -15 -8=7
Solving Equations by Multiplying or Dividing
1. 1/2d= 7. d is 14 because half of 14 is 7.
2. 2/3s= -6. s is -9 because 2/3 of -9 is -6.
3. 4m=10. m is equal to 2.5 because4 times 2.5 is equal to 10.
1. 1/2d= 7. d is 14 because half of 14 is 7.
2. 2/3s= -6. s is -9 because 2/3 of -9 is -6.
3. 4m=10. m is equal to 2.5 because4 times 2.5 is equal to 10.
Rates, Ratios, and Proportions
