First find LCM (least common denominator) which is 12
so now u have 3/4 x 3= 9/12 and 2/3 x 4 = 8/12
now add 9/12 + 8/12 to get answer
try the rest on your own hope dis helped <span>✌️</span>
What you want to do is take one of the 2 equations and isolate one variable. you will then use the value that you find for the variable and plug it back into the other equation. here is how:
This would be easiest to do with the second equation in the set since the x is not being multiplied by anything. So lets isolate the x in the second equation.
add 0.9y to both sides and you get:
x=4.5+0.9y
we now know what x is equal to in terms of y. so lets replace the x in the first equation with the new value. You get:
1.5(4.5+0.9y)-1.9y=-29
Now just solve for y:
6.75+1.35y-1.9y=-29
1.35y-1.9y=-35.75
-0.55y=-35.75
y=65
so now you know that y=65 so plug 65 in as y in the second equation to find x
x-0.9*65=4.5
Now simply solve for x
x-(-58.5)=4.5
x+58.5=4.5
x=-54
Hope this helped! :)
Answer: 13 100 dollar bills.
Step-by-step explanation: you would just do 100*13 which gives you 1300

The next thing you will read in this block
will be two monomials whose greatest
common factor is 4m :
68 x n p m q r y s
and
124 a b g c f m t z
____________________________
And now . . .
Here are two more:
8 m x
and
12 k m
1 foot = 12 inches
(1 foot)³ = (12 inches)³
12³ = 1,728 in³
To change 10 cubic feet into cubic inches
10 ft³ x 1728 in³/ft³ = 17,280 in³
So the answer will be:
C. Multiply by 1,728
