Answer:
3.4x10^-3 mark me the brainlist
Step-by-step explanation:
So I think you should set up an equation like this: 14.95x+16.88y=131.18 , x+y=8
so x=8-y, plug this into the original equation:
14.95(8-y)+16.88y=131.18
Evaluate: 119.60-14.95y+16.88y=131.18
Combine like terms: 119.60+1.93y=131.18
Subtract 119.60 from both sides. You get: 1.93y=11.58
Divide both sides by 1.93. You get y=6
Plug into second equation: x+y=8 ---> x+6=8 and solve for x. x=2
Christine bought 2 video games and 6 CDs. 14.95(2)+16.88(6)=131.18
Answer:
x = -1
Step-by-step explanation:
4(x - 7) + 8(1 - 6x) = 24
distribute
4x - 28 +8 -48x = 24
Combine like terms
-44x -20 = 24
Add 20 to each side
-44x -20+20 = 24+20
-44x = 44
Divide each side by -44
-44x/-44 = 44/-44
x = -1
The mean is 6 because you have to add all the numbers and divide by 5
