Which of the following statements are equivalent? x - y = 2 and x = y + 2

I’m not sure I understand the question. The equations you posted are equivalent. To take x - y = 2 to x = y + 2, you add y to both sides of the equation.

I’m happy to answer more if you let me know in the comments.

Answer:

10x+2

Step-by-step explanation:

First we work on the paranthesis. We will times 5 and 2x to get 10x

and then we times 5 and 3/4 to get 3 $\frac{3}{4}$

So now we have 10x+3 $\frac{3}{4}$ -1.75

Next, we subtract 3 $\frac{3}{4}$ -1.75 which is 2

Lastly we look at the equation as a whole!

10x+2

Marc is building a rectangular wooden frame for his canvas. If the canvas is 7 feet long by 5 feet wide, what is the perimeter o

Assoli18 [71]

Answer:

24 feet

Step-by-step explanation:

Use the perimeter formula, P = 2l + 2w, where l is the length and w is the width.

Plug in the values, and solve:

P = 2l + 2w

P = 2(7) + 2(5)

P = 14 + 10

P = 24

So, the perimeter of the canvas is 24 feet

in triangle abc, the size of angle b is 5 times the size of angle a and the size of angle c is 13° less than 4 times the size of

olasank [31]

Sum of angles of a triangle = 180
a+b+c=180
a + (5a) + (4a-13) = 180
Simplify and solve for a:
10a-13=180
10a=193
a=19.3
b=5*19.3=96.5
c=4*19.3-13=77.2-13=64.2
Check: a+b+c=19.3+96.5+64.2=180 ok.
