Answer 1

Answer:

10.8 m²

Step-by-step explanation:

To find area, we do 3.14*r^2

since diameter = 2 radius divide each by 2

2 and 0.75

A outer= 3.14*2^2

3.14*4

12.56 m²

A inner = 3.14*0.75^2

≈1.8 m²

to find the shaded area subtract the outer from the inner

12.56-1.8=10.76

which rounds up to

10.8 m²

If we use π then we get

about

12.57

and

1.77

subtract to get

10.8 m²

5. A system of equations is below. For what value would
you multiply the first equation to eliminate the x-term?
(y=x+2
3x + 3y = 6

Answers

Answer:

We would multiply the first equation by -3  to eliminate the x-term.

Step-by-step explanation:

Given the system of equations

y = x+2                Equation 1

3x+3y = 6           Equation 2

Multiply the Equation 1 by -3

-3y = -3(x+2) ⇒ -3y = -3x-6 ⇒ -3x+3y = 6

Thus, equation 1 becomes

-3x+3y = 6

Now, adding equation 2

-3x+3y = 6

+

3x+3y = 6

________

0x + 6y = 12

6y = 12

y = 2

Therefore, we would multiply the first equation by -3  to eliminate the x-term.
