:two numbers sum to 65 twice the first subtracted from the second is 5 find the numbers

a+b = 65

b - 2a = 5

Solve one variable in terms of another:

b = 5 + 2a

Substitute in this variable:

a + 5 + 2a = 65

3a = 70

a = 23.3

Use this to find the other variable:

23.3 + b = 65

b = 41.7

Check the

23.3 + 41.7 = 65

65 = 65

ANSWERS:

a = 23.3

b = 41.7

answer: it's d

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
