Answer:

x = -5 and y = 1

Step-by-step explanation:

a) 2x + 5y +5 = 0

a) 2x + 5y = -5

b) 2y = 3x + 17

b) y = 3/2x + 17/2

a) 2x + 5(3/2x + 17/2) = -5

a) 2x + 15/2x + 85/2) = -5

a) 19/2x = -5 - 85/2

a) 19/2x = -95/2

a) x = (-95/2) / (19/2)

x = -5

b) 2y = 3(-5) + 17

b) y = 2/2

y = 1

The ration of two supplementary angles are 1:3 what is the measure of the smaller angle?

Nastasia [14]

Answer:

45°

Step-by-step explanation:

Let :-

The ratio be 1x : 3x

We know :-

The sum of supplementary angles is 180° .

On adding :-

→ x + 3x = 180°

→ 4x = 180°

→ x = 180°/4

→ x = 45°

<h3>Hence the smaller angle is 45° .</h3>

Allen is showing us work in simplifying – 8.3+9.2-4.4+3.7 point identify and explain any errors in his work in or in his reasoni

vladimir1956 [14]

Answer: -8.3 + 9.2 - 4.4 + 3.7

= -8.3 + 9.2 + (-4.4) + 3.7 {Additive inverse}

= -8.3 + (-4.4) + 9.2 + 3.7 {Commutative Property}

= [ -8.3 + (-4.4] + [ 9.2 + 3.7] {Associative property}

= - 12.7 + 12.9

= 0.2
