Solve algebraically<br><br> 8x + 10y = -4<br><br> -4x = 2 + 5y
Rufina [12.5K]

The answer to the first one is:

x=-5/4y+-1/2. Why? 

 In the equation 8x+10y=-4, you subtract 10y form each side which leaves you with 8x=-10y-4. Right? Then you divide each side by 8 which gives you the answer

The answer to the second one is the same answer to the first problem. Why? Because you can already divide each side which gives you x=-5/4y+-1/2.

Hope this helps :^)

Ron bought a keychain for $7 and 3 t-shirts. He spent a total of $37. How much does each t-shirt cost?
White raven [17]

Answer:

$10

Step-by-step explanation:

Subtract the price of the keychain, $7, from the total to find the price of the 3 t-shirts:

$37 - $7 = $30

The 3 t-shirts cost a total of $30.

We assume all t-shirts have the same price.

price of 1 t-shirt = $30/3 = $10

Answer: $10

What is the surface area of the prism in square feet?
frutty [35]

The surface area of the rectangular prism is 52 square feet (ft^{2}), if the height is 4 feet, width is 3 feet and depth is 2 feet.

Step-by-step explanation:

          The given is,

                    A rectangular prism of

                     Let, h - height of the rectangular prism

                            w - Width of the rectangular prism

                            d - Depth of the rectangular prism

Step:1

        From given,

                     h = 4 feet

                     w = 3 feet

                     d = 2 feet

Step:2

        Formula to calculate the surface area of the rectangular prism is,

                      A = 2 (wd+hd+hw)

       Substitute the values of w,d and h

                           = 2 [(3×2) + (4×2) + (4×3)]

                           = 2 (6+8+12)

                           = 2 × 26

                           = 52

                       A = 52 Square feet

Result:

        Thus the surface area of the rectangular prism is 52 square feet (ft^{2}), if the height is 4 feet, width is 3 feet and depth is 2 feet.
