Answer:
x(2x+3)
Step-by-step explanation:
2x^2+3x=x(2x+3)
Answer:
66%
Step-by-step explanation: 2/3 is .66666666666666...
4.25(15)+4.25(1.5)(7)+0.21(1345)=
63.75+44.625+282.45=$390.825
=$390.83
Answer:
x = x+9
Step-by-step explanation:
well that is the only way you can do it as we do not know about what x is. also, if you meant by x + (x*9), you can represent that as x*10
Answer:
X = 8, Y = 8
Step-by-step explanation:
Step 1) Solve for Y w/ bottom equation to yield - y = -2/3x + 40/3.
Step 2) substitute equation into x + y = 16 to get 1/3x + 40/3 = 16 multiply by 3 to clear the fractions and get x + 40 = 48 - subtract 40 by both sides to get x = 8.
Step 3) Plug x = 8 into the bottom equation to get 48 + 9y = 120, subtract 48 by both sides to get 9y = 72 and then divide by 9. The product is y = 8.
