Answer:

x ≥ 3/7

Step-by-step explanation:

2(2x - 3) ≥ -3(5x) + 5x

~Distribute both sides

4x - 6 ≥ -15x + 5x

~Simplify the right side

4x - 6 ≥ -10x

~Subtract 4x to both sides

-6 ≥ -14x

~Divide -14 to both sides

6/14 ≤ x

~Simplify

x ≥ 3/7

Best of Luck!

Answer:

x ≥ 3/7

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

4x−6 ≥ −10x

Step 2: Add 10x to both sides.

4x−6+10x ≥ −10x+10x

14x−6 ≥ 0

Step 3: Add 6 to both sides.

14x−6+6 ≥ 0+6

14x≥6

Step 4: Divide both sides by 14.

14x/14 ≥ 6/14

A math textbook is 1 1/4 in. thick. how much shelf space is needed for 30 copies of the book?
inysia [295]
Hello!

You have to multiply 1 1/4 by 30 because each math book is 1 1/4 in. thick, and 30 books is 1 1/4 by 30. First change 30 and 1 1/4 to an improper fraction.

\frac{30}{1} \times    \frac{5}{4} =  \frac{150}{4} =  37  \frac{1}{2}

Please help, and plz don't be saying this is the right answer if u dont know for sure.
zepelin [54]

Answer:

135 degrees

Step-by-step explanation:

(8x-7)+(12x+57)=180

combine like terms

20x+50 = 180

subtract 50 on both sides

20x = 130

divide by 20

x = 130/20

x = 13/2

x = 6.5

cpq = 12x+57

cpq = 78 + 57

cpq = 135
