Answer:
p = q/5 - 9r/5
Step-by-step explanation:
Step 1: Write equation
5p + 9r = q
Step 2: Solve for <em>p</em>
<u>Subtract 9r on both sides:</u> 5p = q - 9r
<u>Divide both sides by 5:</u> p = q/5 - 9r/5
Answer:
x = 35° , y = 90°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
145° is an exterior angle of the triangle , then
y + 55° = 145° ( subtract 55° from both sides )
y = 90°
the sum of the 3 angles in a triangle = 180° , then
x + y + 55° = 180°
x + 90° + 55° = 180°
x + 145° = 180° ( subtract 145° from both sides )
x = 35°
They are equal because let's say you have 6 slices of pizza and you and 5 friends came over to your house to have pizza all of you had one slice because their were 6 slices in the beginning and you and your 5 friends had one slice so that is 1 whole pizza that you and you friend ate
