Answer is (9, 7)

Step by step

Rule: 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x).

This means, we switch x and y and make x negative.

So

Given: m∠A + m∠B = m∠B + m∠C Prove: m∠C = m∠A
mel-nik [20]

Answer:

See below.

Step-by-step explanation:

m∠A + m∠B = m∠B + m∠C

Use the subtraction property of equality to subtract m<B from both sides of the equation.

m∠A + m∠B - m<B = m∠B - m<B + m∠C

m∠A = m∠C

inna [77]

Answer:

  • drink cost: $1.75
  • slice of pizza cost: $2.25

Step-by-step explanation:

Let d and p represent the costs of a drink and a pizza slice, respectively. The two orders have a value ...

  d + 3p = 8.50

  2d + 2p = 8.00

Subtracting the second equation from twice the first gives ...

  2(d +3p) -(2d +2p) = 2(8.50) -(8.00)

  4p = 9.00 . . . . . simplify

  p = 2.25 . . . . . . divide by 4

Solving the first equation for d and putting in the value, we have

  d = 8.50 -3p = 8.50 -3·2.25 = 8.50 -6.75

  d = 1.75

The cost of a drink is $1.75; the cost of a pizza slice is $2.25.
