Answer:

A = 6, B = 1.

Step-by-step explanation:

3A + 2B = 20

2A + B = 13          Multiply this by -2:

-4A - 2B = -26     Add this equation to the first equation:

-A = -6

A = 6.

and from the second equation:

2(6) + B = 13

B = 13 - 12 = 1.

3A+2B=20

2A+B=13 ➡×(-2)➡-4A-2B=-26

3A+2B-4A-2B=20-26

-A=-6 ➡A=6

2(6)+B=13➡B=1

Solve for x. -2(16 - 4x) - 8 = 6(x + 2)
Amanda [17]
So...

-2(16-4x)-8=6(x+2)             Multiply
-32+8x-8=6x+12                 Add like terms
-40+8x=6x+12                    Subtract 6x from both sides
-40+2x=12                          Add 40 to both sides
2x=52                                 Divide 2 from both sides
x=26                                   Substitute to check
-2(16-4(26))-8=6((26)+2)   Add and multiply in parenthesis
-2(-88)-8=6(28)                  Multiply
176-8=168                         Subtract
168=168                          

So x=26

I hope this helps! Have a great day!

If a large sized pizza of diameter 35 cm is kept on a rectangular base of dimensions 50 cm x 60 cm. Find the area of the base ex
Yuki888 [10]

Answer:

2037.89

Step-by-step explanation:

The area of a circle is πr²

This means that the area of the pizza is π*17.5^2

This means that the area =962.11275016187

We then need to find the area of a rectangle which is shown throuhg lenght*width

50*60=3000

We then need to find out the area of the box excluding the pizza so we subtract the area of a pizza

so we have

3000-962.11275016187=2,037.88724983813

Round and get 2037.89
