Answer: y=-x+5 and y=-14 ![2x+2y=10 subtract 2x from both sides\\2x+2y-2x=10-2x \\2y=10-2x divide both sides by 2\\y=5-x rewriting using the commutative property\\y=-x+5](https://tex.z-dn.net/?f=2x%2B2y%3D10%20%20%20subtract%202x%20from%20both%20sides%5C%5C2x%2B2y-2x%3D10-2x%20%5C%5C2y%3D10-2x%20%20divide%20both%20sides%20by%202%5C%5Cy%3D5-x%20%20rewriting%20using%20the%20commutative%20property%5C%5Cy%3D-x%2B5)
Step-by-step explanation:
Slope Intercept form is y=mx+b
Equation A:
Answer:
∠F = 50°
Step-by-step explanation:
The sum of all three angles in a triangle = 180°
∠F = 180° - 30° - 100° = 50°

Answer:
27 years old
Step-by-step explanation:
let Sydney's age be x, then
Devaughn's age is 3x ( three times Sydney's )
The sum of their ages is 108, thus
x + 3x = 108
4x = 108 ( divide both sides by 4 )
x = 27
Sydney is 27 years old
Answer:
6 divided by some number y
Step-by-step explanation:
Let y be some unknown number
Given an expression 6/y
The slash sign (/) there means division. Hence the statement can be described as 6 divided by some number y
