Write an equation for the following statement.
Three less than six times a number squared is seven
6x2-3 = 7
Solve for x. Don't forget about your negatives.
6x-12 = 12
x = 0
Remember the sign matters and don't forget your negatives. Solve for x.
2x-3 > 5
x>4
Solve for x.
|2x| = 6
x={-3, 3}
Solve for k.
k+j = x/y
k= x/y - j
Write an expression for the following statement.
Nine less than a number squared.
x2 -9
Solve for x. Don't forget about your negatives.
4(2x-8) = 64
x = 12
Remember the sign matters and don't forget your negatives. Solve for x.
-5x +4< 24
x>-4
Solve for x.
4|3x -8|+2= 10
x = {10/3, 2}
Solve for k.
a+k= w-v
k = w-v-a
Write an expression to match the following statement.
Six times a number plus another number tripled.
6x+3y
Solve for x. Don't forget about your negatives.
3(x-2) = 6(5x+2)
x = -2/3
Remember the sign matters and don't forget your negatives. Solve for x.
-2x+4>-2(-5x-6)
x<-2/3
Solve for x.
|4x-3| > 9
|4x-3|>9
4x-3>9 or 4x-3<-9
x>3 or x<-3/2
Solve for a.
am = p+q
a = (p+q) / m
Write an expression to match the following statement.
Four more than an number and all of that tripled
3(x+4)
Solve for x.
-2(-2x-5) = 2(-3x+5)
x = 0
Remember the sign matters and don't forget your negatives. Solve for x.
-2(3x-4) < 2(x-1)
x>5/4
Solve for x.
|2x+3| -7 < 2
|2x+3|< 9
2x+3<9 and 2x+3>-9
Thus, x<3 and x>-6 can also be written as -6<x<3
Solve for d.
d(c-a) + p= x-y
d= (x-y-p)/(c-a)
Write an equation for the following statement. Then SOLVE.
Six times a number is eight less than 20
6x = 20-8
x = 2
Judy wants to buy some video games. She wants one video game that costs $15, one that costs $12 and one that costs $23. She has saved $20 thus far. At her job she is working for $5 and hour. How many more hours does she need to work?
The equation you should have come up with is: 5x+20 = 50, where x is number of hours
Final Answer: 6 hours
Jim wants to buy a bike that is at least $500. He already has $125. If he saves $15 per week. How long does he have to wait to buy the bike?
The inequality: 125+15x>500 with x being the number of weeks
So x > 25
Write out the compound inequality and solve.
-4|2x-3|<-20
Answer:
|2x-3|>5
2x-3 >5 or 2x-3<-5
So x>4 or x < -1
Solve for r.
A = π r2
(A/π )1/2
