Systems of equation substitution 2x+4y=24 x=4y

Mathematics
1 answer:
antoniya [11.8K]3 years ago

Answer:

(x, y) = (8, 2)

Step-by-step explanation:

substitute x = 4y into the other equation

2(4y) + 4y = 24

8y + 4y = 24

12y = 24 ( divide both sides by 12 )

y = 2

substitute y = 2 into x = 4y

x = 4 × 2 = 8

solution is (8, 2 )

Solve for x:-ax+3b>5
Salsk061 [2.6K]
Our current equation is:
-ax + 3b > 5

Our objective is to solve for x, so let's first get -ax by itself.
Subtract 3b from both sides.

-ax > -3b + 5
Now, we have -a multiplying x, so we need to perform the opposite order of operations (like previously shown with 3b).
Divide both sides by -a.
Remember to flip the inequality when multiplying or dividing by a negative.

x <_ (-3b + 5)/-a is your final answer.

I hope this helps!

Answer:

Step-by-step explanation:

2)  r = 16/2 = 8 cm

Area of top and bottom = 2*πr²

                                        = 2 * 3.14 * 8 * 8

                                       = 401.92 cm²

Midlle part = h * πd

                 = 6 * 3.14 * 16

                = 301.44 cm²

Total = 401.92 + 301.44

        =        703.36 cm²

3) Area of front and back = 2* \frac{1}{2}*b * h\\

                                         = 2*\frac{1}{2} * 3 * 4\\\\= 12 cm^{2}

Area of bottom = length * breadth

                           = 12* 3

                          = 36 cm²

Area of left =  12 * 4

                  = 48 cm²

Area of right = 12 * 5 = 60 cm²

Total = 12 + 36 + 48 + 60 = 156cm²
