The expression simplified is 21
27/3 +6*2
(27/3)+(6*2)
(9)+(12)
9+12

Hi there!
To solve both of you questions, you will need to use the cross product method :
<u>Finding "x" :</u>

So you have to do :
(4 ×
) ÷ 2 = x gallon
4 times
is the same thing as 4 times 0.5, which equals 2.
2 ÷ 2 = x gallon
1 = x gallon
So the amout for x would be : 1 gallon
<u>Finding "y" :</u>
You could do the exact same method as we did for finding "x", but the easiest and fastest way to get our answer is just by multiplying the amout we got for "x" by 2 because we are putting 8 scoops instead of 4 for "x" (and 4 times 2 = 8) :
1 gallon × 2 = y
2 gallons = y
So your answer is : The amount for y would be : 2 gallons
There you go! I really hope this helped, if there's anything just let me know! :)
Inv1 investment 1
inv2 investment 2
A) inv1 + inv2 = 33,000
B) .04 inv1 + .07 inv2 = 1,950
Multiplying A) by -.04
A) -.04 inv1 - .04 inv2 = -1,320
Then adding B)
B) .04 inv1 + .07 inv2 = 1,950
.03 inv2 = 630
inv2 = 630 / .03
inv2 = 21,000 invested at 7%
inv1 = 33,000 -21,000=
12,000 invested at 4%
Answer:
WHAT IS THE LINEAR EQUATION?
y=2-3x and y=x/3+2
WHY IS THAT THE LINEAR EQUATION
Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y
WHAT IS THE NONLINEAR EQUATION
Y = x(3x+2)
WHY IS THAT THE LINEAR EQUATION
A nonlinear function has more than one independent variable. The independent variable is x.
