Intro to Algebra Linear Equations

Simplify by combining like terms:

5a + 2b - 3a + 4

• 8a + 2b + 4

• 2a + 2b + 4

• 8ab

• 4ab + 4

Simplify: 2(4 + 9w)

• 8+9w

• 2+9

• 8+18w

• 2+9w

Simplify the expression: 4\left(3+2w\right)-w+2

• 7w+14

• 19w+2

• 21w

• w+14

• -5x-6

• -2x-6

• 2x-2

• -5x+4

• 9x - 2y = 36

• 9x - 2y = 26

• 9x - 2y = -40

• 9x - 2y = -10

Suppose that the water level of a river is 34 feet and that it is receding at a rate of 0.5 foot per day. Write an equation for the water level, L, after d days. 

• L = 34 - 0.5(d)

• L = 34(d) - 0.5

• d = 34 - 0.5(L)

Carter sells sports videos to local businesses in his area. His daily wage, W, is based on the number of hours he works, H, at the minimum wage of $7.25 per hour, plus $10 to cover gas and lunch expenses. Which equation best describes this relationship?

• W=10H+7.25

• W=7.25H+10

• H=10W+7.25

• H=7.25W+10

Write 'True' or 'False' 
The solution of a linear equation is always an integer

• TRUE 

• FALSE

• 9

• 1

• 0

• 9y

• 8y+5
• 3y+3
• 7y+5
• 7y+4
