8x + 2 = 35
Eight times a number plus two equals thirty-five
5-x=21
x= -16
A dripping faucet wastes 3 cups of water every 2 days. How much water is wasted in a week?
3/2 = x/7
x= 10.5 cups/week
|5x + 4| = -877
No Solution
w/12=10/15
w = 8
Five times x squared less two is thirty.
5x2 - 2 = 30
3/5 x-4=36
x=200/3 or 66.7
The thermometer is accurate to +- 2oF. Write an absolute value equation that could be used to find the greatest and least possible temperatures if the thermometer reading is 17oF.
|x-17| = 2
x=19 Degrees F
x= 15 Degrees F
|3x - 6| = 12
x = 6 and x = -2
(x-3)/5 = 6/10
x=6
3(x-4) = 21
Three times the difference of a number and four equals twenty-one
Solve for x
(32-hx)/5 = 20
x=-68/h
Ethan bought a notebook and a box of pencils for $5. The notebook cost $3 and there are 10 pencils in a box. Write and solve an equation to find the cost of one pencil.
10x + 3 = 5
x= $0.20/pencil
|x-2|=17
x= 19 and x= -15
(x+15)/10 = 2/5
x= -11
Four times the sum of a number x and a number y is equal to 20
4(x+y)=20
6(x-1)=3(2x-7)
No solution
The coldest temperature recorded in Alaska was -80oF. This was 10oF warmer than the coldest temperature recorded in Siberia. Write an equation that can be used to find the coldest temperature recorded in Siberia. What is the coldest temperature recorded in Siberia?
x + 10 = -80
x = -90oF
|2y+6| = 30
y= 12
y= -18
(9y-3)/9 = (5y+5)/3
y = -3
