Answer:

x > 5

Step-by-step explanation:

2x - 5x < 3 - 18

-3x < -15

Divide everything by ÷ 3 and flip inequality because it's negative.

Answer:

15/7 < x

Step-by-step explanation:

Simplify using PEMDAS, and remember that multiplying/dividing a negative flips the sign of the inequality.

-5x - 3 < 2x - 18  (Add 18 to both sides)

-5x + 15 < 2x (Add 5x to both sides)

15 < 7x (Divide both sides by 7)

15/7 < x

8+—3(6+—6a) help please
LenKa [72]
We know that:

(+)+(-)=(-)

and:

(-)*(+)=(-)

8+(-3)[6+(-6a)]=8+(-3)*6+(-3)*(-6a)=8-18+18a=(-10)+18a

if you have solve for a then:

(-10)+18a=0
18a=10
a= \frac{10}{18}
a=\frac{5}{9}

Solve showing all work and simplify completely:<br> 9/18 + 1/3
ss7ja [257]

Answer:

5/6

Step-by-step explanation:

9/18 + 1/3 <Need the same denominator so find the lowest common multiple.

3 6 9 12 15 18 < multiples of 3

if 3 goes into 18 than it will be our LCM

3 goes into 18 6 times so multiply 1 and 3 by 6 and rewrite the equation

9/18 + 6/18 < just add 9 + 6 and place it over 18

15/18 <this number can be simplified so write out their factors and pick the highest one to divide by one they have in common.

1 3 5 15 <Factors of 15

1 2 3 6 9 18 <Factors of 18

3 is the highest one they both have so divide both 15 and 18  by 3

15/3 is 5 and 18/3 is 6

put the 5 and 6 in their proper places and you have 5/6 or .83333333333...
