I am thinking of a number. I subtract 10 then divide by 2 and I now have 19. What was my original number? (Hint: Start with the

number at the end, 19, and work in "reverse". In other words, 19 × 2 + 10.)

x=96


all interior angles equal 180


Subtract exterior andgles by 180 to get interior angles because they are supplementary

180-134=46

180-130=50


Get the third angle inside the triangle

180-50-46=84


subtract by 180 to get x because they are supplementary

180-84=96


Therefore x =96

If three pounds of coffee costs $22.56, what is the cost of 1
NeX [460]

Answer:

$7.52 = 7 dollars and 52 cents.

Step-by-step explanation:

Given that three pounds of coffee = $22.56

1 pound of coffee = $22.56/3

Thus, we would have:

\frac{22.56}{3} = 7.52.

A pound of coffee = $7.52

$7.52 = 7 dollars and 52 cents.

What is the expression for the area of the old garden if the perimeter is 6w+8, where W represents the width?
musickatia [10]

Answer:

w(2w+4)

Step-by-step explanation:

we know A = l * w

and Perimeter = 2l + 2w

we want to find l in terms of w

2l + 2w = 6w + 8

2l = 4w + 8

l = 2w + 4

so A = w * (2w + 4)

In her metalwork class, Anja cut a square of
Paul [167]

Given:

Anju cut square of tin, of edge 3.7 cm, from a larger square of edge 6.3 cm.

To find:

The area of the remaining tin.

Solution:

Area of a square is:

Area=a^2

Where, a is the edge of the square.

Area of the smaller square is:

A_1=(3.7)^2

A_1=13.69

Area of the larger square is:

A_2=(6.3)^2

A_2=39.69

The area of the remaining tin is:

A=A_2-A_1

A=39.69-13.69

A=26

Therefore, the area of the remaining tin is 26 sq. cm.
