13 = x/-11
-143
4x - 4 + x = 1
x = 1
David K borrowed $100 from David C to buy V-bucks. If David K has already paid back $25, how much money does he still owe David C?
x + 25 = 100
x = $75
(x/4) - 8 > -12
x > -16
"The sum of a number and 5 is no less than 23"
x + 5 >= 23
x >= 18
(-3/2) + x = -17/8
x = -5/8
3(2-5x) + 2 = -112
x = 8
10 tickets at the carnival cost $25, how much does one ticket cost?
10x = 25
x = $2.50
7 - 4x > -73
x < 20
"15 more than the product of a number and -3 is no more than 45"
15 - 3x <= 45 or -3x + 15 <= 45
x >= -10
7x - 4 = -116
x = -16
-(4x + 3) = 5 - 6x
x = 4
"13 subtracted from the product of a number and -3 is 16"
-3x - 13 = 17
x = -10
-4(-2x + 6) < -88
x < -8
Mr. Hawley needs $500,000 to fix the school after "accidentally" dividing by 0 and creating a mini blackhole. How much money does he need to pay if he wants the total balance owed to be a maximum of $300k?
500,000 - x <= 300,000
x >= 200,000
-6 = -9 + (x/3)
x = 9
8(7x - 5) = 8(1 + 4x)
x = 2
"The difference of 5 and twice a number is 6"
5 - 2x = 7
x = -1
2(-1 - 8x) > -5x -2(1-3x)
x < 0
Will is saving up for a PS5. If he needs at least $600, and he has already saved $240, how much is his total paycheck if he only needs to save five-twelfths of it?
240 + (5/12)x >= 600
x >= $864
9x2 - 13 = 12
x = +/- 5/3 or 1.67
-4 - 3(x+5) = -10 - 3(3+x)
x = infinite solutions ∞
Jonah ran his mile 83 seconds faster than Mr. Hawley. If their combined time was 13 minutes and 47 seconds, how long did it take Jonah?
J + (J + 83) = 827 seconds
J = 6 minutes 12 seconds (Dang!)
-3 - 4(3 + 2x) < -2x - 15
And which of these are solutions for the inequality?
-2, -1, 0, 1, 2
x > 0
1, 2
The President of Math has asked Mr. Hawley to throw the best Pi Day Party this nation has ever seen. If he wants each man, woman, and child to have at least 3 pies each at $4.50 per pie, and a maximum budget of $1200, how many people can he invite?
3*4.50x <= 1200
x <= 88.89 people What is 0.89 people?
So round down to
x<= 88 people
