Answer:

Step-by-step explanation:

7x + 5y = -13 ....multiply by 2

-2x - 7y = 26 .....multiply by 7

-------------------------

14x + 10y = -26 (result of multiplying by 2)

-14x - 49y = 182 (result of multiplying by 7)

-----------------------add

-39y = 156

y = -156/39

y = -4

7x + 5y = -13

7x + 5(-4) = -13

7x - 20 = -13

7x = -13 + 20

7x = 7

x = 7/7

x = 1

check...

-2x = 7y + 26

-2(1) = 7(-4) + 26

-2 = -28 + 26

-2 = -2 (correct)...it checks out

answer is : x = 1 and y = -4 or (1,-4)

Tpy6a [65]

Answer:

Area of the sandbox cover = 12 ft²

Step-by-step explanation:

The area of a kite is given as the product of the two diagonals of the kite divided by 2.

Area of kite = (xy/2)

where x and y are the diagonals of the kite.

The sandbox cover, in shape of a kite has a width of 6 ft and a height of 4 ft.

These two dimensions are the diagonals of the kite. Hence, the area of a kite is

A = (6×4/2) = 12 ft²

Hope this Helps!!!

Solve the equation for m. Show your work -40 - 6m + 1 = - 2
bekas [8.4K]

Answer:

\bold{m \ = \ \frac{-37}{6} \ Or  \ -6.16666666667}

Explanation:

-40 - 6m + 1 = - 2

  • Simplify Both Sides Of The Equation

−40 − 6m + 1 = −2

−40 + −6m + 1 = −2

(−6m) + (−40 + 1) = −2 (Combine Like Terms)

−6m + −39 = −2

= −6m − 39 = −2

  • Add 39 To Both Sides

−6m − 39 + 39 = −2 + 39

−6m = 37

  • Divide Both Sides By -6

-6m / -6 = 37 / -6

  • Simplify

\bold{m \ = \ \frac{-37}{6} \ Or  \ -6.16666666667}
