Answer 1

Answer:

x = 7/10; y = 21/5

Step-by-step explanation:

y = 6x

4x + y = 7

Since the first equation is already solved for y, we can easily use the substitution method. We substitute 6x for y in the second equation and solve for x.

4x + y = 7

4x + 6x = 7

10x = 7

x = 7/10

Now we use the first equation and substitute 7/10 for x and solve for y.

y = 6x

y = 6 * 7/10

y = 42/10

y = 21/5

Answer: x = 7/10; y = 21/5

What is the total surface area of the rectangular prism in square inches?

Answers

Answer:

272 square inches

Step-by-step explanation:

Given

[tex]l = 8[/tex] --- length

[tex]w = 2[/tex] --- width

[tex]h = 12[/tex] ---- height

Required

Determine the total surface area (SA)

This is calculated using:

[tex]SA = 2 * (lw + wh + lh)[/tex]

[tex]SA = 2 * (8*2+2*12+8*12)[/tex]

[tex]SA = 2 * 136[/tex]

[tex]SA = 272[/tex]

The total surface area is 272 square inches

x=11 should be the answer lmk if so

Answer:

x = 18

Step-by-step explanation:

m∠1 & m∠3 are vertical angles. By definition of vertical angles, their measurements will be the same.

It is given that:

m∠1 = 4x - 14

m∠3 = 58°

Set the two angles equal to each other:

4x - 14 = 58

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, add 14 to both sides of the equation:

4x - 14 (+14) = 58 (+14)

4x = 72

Next, divide 4 from both sides of the equation:

(4x)/4 = (72)/4

x = 72/4 = 18

18 is your answer for x.
