One Step
Solve for x: 25 + x = 100
x = 75
8 = 5j - 17
j = 5
3b - 5 - 2b = 5
b = 10
Write an equation represents the following:
"Five more than twice a number is equal to 17"
2x + 5 = 17
The Empire State Building is 1250 feet tall. This is 140 feet more than twice the height of the Washington Monument. How tall is the Washington Monument?
140 + 2w = 1250
w = 555 feet tall
-8x = -64
x = -8
(m/-2) + 7 = 21
m= -28
3(x -4) = 15
x = 9
Write an equation represents the following:
"Five less than three times a number is forty-six."
3x - 5 = 46
Lucas was painting a long fence. When he had painted 8 feet less than 3/4 of the fence, he noticed he had painted 85 feet. How long is the fence he is painting?
(3/4)x - 8 = 85
x = 124 feet
-4x = 2/5
x = - 1/10 or x = - 0.1
49 = 5y - 26
y = 15
5n + 4 - 8n = -5
What is n = 3?
Write an equation represents the following:
"The sum of seven and three times a number is 10."
7 + 3x = 10
A group of 3 friends each have video games at their home. Then each friend buys 5 more video games. Now the three friends have a total of 30 video games. How many video games did each friend start with?
3(x+5) = 30
x = 5
(2/3)x = - 25
x = - 37.5 or - 37 1/2
287 = 78.2 + 0.5x
x = 417.6
3s + 3(s-10) = 36
s = 11
Write an equation represents the following:
The product of three and the sum of a number and two is equal to six.
3(x + 2) = 6
A bag of candy was shared equally among 4 friends. Each friend gave away 7 pieces of candy. They each ended up with 8 pieces of candy. How much candy was in the bag at the beginning.
(c/4) - 7 = 8
c = 60
-5 + w = -3/4
w = 4.25 or w = 4 1/4
(5/2)t+ 1/4 = 3/5
t = 7/50
4(y-2) + y= -13
y= -1
Write an equation represents the following:
"Eight less than five times a number equals 25."
5x - 8 = 25
Luis is setting up a new tent during a camping trip. The tent came with 8 feet of rope. He uses 12.5 inches of the rope to tie a tarp on the top of the tent. Then, the remaining rope should be cut into 4 1/2 inch section to tie the tent to stake in the ground. How many 4 1/2 inch sections of rope Luis can cut from the rope?
8 ft = 8 x 12 = 96 inches
(4 1/2)x + 12.5 = 96
x = 18.555...
