Solve:<br> -8(x - 3) + 5x &lt; 9(x + 12)<br> This is Algebra 1
Flauer [41]

Answer:

x>−7

Step-by-step explanation:

left side:

-8(x-3)+5x

distribute -8 into (x-3)

-8x+24+5x

combine like terms

-3x+24

right side:

9(x+12)

distribute 9 into (x+12)

9x+108

-3x+24<9x+108

Subtract 24 on both sides

-3x< 9x+108-24

combine like terms

-3x<9x+84

Subtract 9x on both sides

-3x-9x<+84

combine like terms again

-12x<84

Multiply both sides by -1 (reverse the inequality)

(-12x)(-1)>84(-1)

12x>-84

divide both sides with 12

\frac{12x}{12}>\frac{-84}{12}

x>−7

hope this helps

Vinny is serving punch to guests at a party. He has 2/3 of a gallon of punch, and he pours 3/64 of a gallon into each guest's cu
Nata [24]
Divide 2/3 by 3/64 and you will get the number of cups of punch. It doesn't come out evenly, but that's the way to do this.there is a total of 2/3 gallon of punch. Each guests has a cup of 3/64 gallon of punch. Now many 3/64 gallon of punch can you fit in 2/3 gallon of punch, that will tell you how many guests there are. so naturally we want to divide<span> ( 2/3 ) / ( 3/64).</span>

Simplify. (−5 p 4 z 6 u) 3
ser-zykov [4K]
In this expression, solve the multiplication in the parenthesis. 
-5×p×4×z×6×u
since multiplication is commutative, 
-5×p×4×z×6×u=-5×4×6×p×z×u= -120pzu

Now multiply this by 3.
(-5p4z6u)3 = (-120pzu)3 = -360pzu
