What is the value of x+y? Eight grade math

Mathematics
1 answer:
atroni [7]2 years ago
6 0

Hello! The value of x+y is 12

Make sure to read an explanation so you can understand the solution better.

Any questions about the answer and explanation can be asked through comments.

Step-by-step explanation:

We can simply solve the system of equations by substituting x = 3y in the first equation

\large{2x + 2y = 24} \\  \large{2(3y) + 2y = 24} \\  \large{6y + 2y = 24} \\  \large{8y = 24} \\  \large{y = 3}

Therefore, the value of y is 3. Then we substitute the value of y in x = 3y.

\large{x = 3y} \\  \large{x = 3(3)} \\  \large{x = 9}

Therefore, the value of x is 9.

Since you want to find x+y, simply add 9 and 3 as we get 12.

Therefore x+y = 12.

Answer:

Carmen bought 5 pounds of coffee

Step-by-step explanation:

The cost of buying coffee is $8.44 per pound. Let us assume she bought x pound of coffee, this means that she spent $8.44x on coffee.

She went to the coffee store with $80 gift card and left with $37.80, this means that after spending $8.44x from the initial $80, she had $37.80. To find the number of pounds she bought, we are to use the following equation:

80 - 8.44x = 37.80

8.44x = 80 - 37.80

8.44x = 42.2

x = 42.2/ 8.44 = 5

x = 5 pounds.

Please find the value of x in the figure
notka56 [123]

Answer:

Step-by-step explanation:

E is the midpoint of Ac & D is the midpoint of AB

DE = (1/2)BC        {Midpoint theorem}

x +1 = \dfrac{1}{2}(4x - 6)\\\\\\
Multiply \ the \ whole \ equation \  by 2\\\\
2*(x+1) =2*\dfrac{1}{2}*(4x - 6)

2*x + 2*1 = 4x - 6

2x + 2 = 4x - 6

Add 6 to both sides

2x + 2 + 6 = 4x

2x + 8 = 4x

Subtract 2x from both sides

8 = 4x - 2x

2x = 8

Divide both sides by 2

x = 8/2

x = 4

The graph of f(x) shown below
bonufazy [111]

Answer:

C

Step-by-step explanation:

the "-" sign can't be true, because that would have turned the whole graph of x² upside-down. but it is not.

so, we need a positive sign for the x term.

and the whole graph is shifted to the right. so the functional value of x of F(x) is now the same that happened "earlier" (for smaller x) with G(x). so, the argument "x" is now reduced (by 3 units, as the graph is shifted right by 3 units) in the calculation compared to the original G(x) calculation.

therefore, the ...(x-3)... expression is right.

so, positive sign and "(x-3)" is only in C.
