-3x - 12 > 8x + 21

Step 1: Combine like terms

x's go with x's (-3x and 8x). To do this add 3x to both sides

(-3x + 3x)  - 12 > (8x + 3x) + 21

-12 > 11x + 21

Normal numbers go with normal numbers (-12 and 21). To do this subtract 21 to both sides

(-12 - 21) > 11x + (21 - 21)

-33 > 11x

Step 2: Isolate x by dividing 11 to both sides

-33/11 > 11x / 11

-3 > x

Hope this helped!

Answer:

x\:

Step-by-step explanation:

The given inequality is:

-3x-12\:>\:8x+21

We group similar terms to obtain:

-12-21\:>\:8x+3x

Combine the similar terms to obtain:

-33\:>\:11x

Divide both sides by 11;

-3\:>\:x

Or

x\:

3/4 + 1/2
multiply 1/2 denominator and numerator by 2 to match 3/4
= 3/4 + 2/4 = 5/4 (copy same denominator add numerator)

2/6 + 1/3
divide 2/6 denominator and numerator by 2 to match 1/3
= 1/3 + 1/3 = 2/3 (copy same denominator add numerator)

5/9 + 2/3
multiply 2/3 denominator and numerator by 3 to match 5/9
= 5/9 + 6/9 = 11/9 (copy same denominator add numerator)



6/9 -1/5
cross multiply 6x5 - 1x9 for numerator
for denominator multiply 9x5
=30/45 - 9/45= 21/45
divide num and den by 3
=7/15


5/8-1/3
cross multiply 5x3-1x8 for numerator
multiply 8x3 for denominator
= 15/24 -8/24 =7/24

Hugo is pumping regular gas into his truck. Write and solve an absolute value equation to represent how many gallons of gas will
xxTIMURxx [149]

Answer:

9.8 < x < 10.2

Step-by-step explanation:

Given that:

Total amount = $25

Error = ±5

Let gallon of gas pumped = g

Price of regular gas = $2.50

Gallon of gas to be pumped = total amount / price per gallon

Gallon of gas = $25 / $2.50 = 10 gallons

Error = $0.5 / $2.5 = 0.2

(10 - 0.2) < x < (10 +. 0.2)

9.8 < x < 10.2
