X=hours of plan A
y=hours of plan B
wed: 5x+6y=12
thu: 3x+2y=6
so
5x+6y=12 and
3x+2y=6
we can eliminate y's by multiplying 2nd equation by -3 and adding to first equation
-9x-6y=-18
<u>5x+6y=12 +</u>
-4x+0y=-6
-4x=-6
divid both sides by -4
x=-6/-4
x=3/2
x=1.5
sub back
3x+2y=6
3(1.5)+2y=6
4.5+2y=6
2y=1.5
y=0.75
Plan A=1.5 hours
Plan B=0.75 hours
Answer:
Yes!
Step-by-step explanation:
It is because your still getting the same number 3 because even though your multiplying and dividing it still works
Answer:
x≥11
Step-by-step explanation:
4x-3≥41
4x≥41+3 -44
x≥44/4 = 11
I believe that the answer is x=12.
Answer: 290
Step-by-step explanation:
Plug in the value 5 for x
2(5) (4+5(5))
Then use PEMDAS to solve:
P - parentheses (Multiple then add)
5(5)=25
4+25=29
M - multiple
2(5)=10
10 (29) = 290
