Answer:
Step-by-step explanation:
subtract m from both sides and you get - 3/4m
divide 2/3 divided by -3/4
-8/9
Answer:A polynomial added to a polynomial also still gives a polymonial
Set Abe as x
set Bella as y
set Carlos as z
<span>Bella has earned 10 less credits than Abe
y=x-10
</span><span>Carlos has earned two less than double the number of Abe’s credits
</span><span>z=2x-2
</span><span>Altogether, they have earned a total of 136 credits
</span><span>x+y+z=136
replace y with x-10
replace z with 2x-2
x+(x-10)+(2x-2)=136
solve for x
4x-12=136
4x=148
x=37
We now know Abe earned 37 credits
To find how much Bella earned plug in 37 for y=x-10
y=27
To find how much Carlos earned plug in 37 for z=2x-2
z=72
Therefore,
Abe earned 37 credits
Bela earned 27 credits
Carlos earned 72 credits
