Answer:
Lori's age is 15 years old and Michelle's age is 5 years old now
Step-by-step explanation:
Let
x-----> Lori's age
y ----> Michelle's age
we know that
-----> equation A
----> equation B
substitute equation A in equation B and solve for y
Find the value of x
therefore
Lori's age is 15 years old and Michelle's age is 5 years old now

Answer:
25 degrees
Step-by-step explanation:
In the picture attached, the lines and the angles are shown. There we can see that:
85° + 2x° + (x-10)° = 180°
75 + 3x = 180
x = (180 - 75)/3
x = 35°
∠3 and ∠(x-10)° are alternate interior angles, therefore they are congruent, so:
∠3 = x - 10
∠3 = 35 - 10
∠3 = 25°
Quadrant II is the answer
Answer:
x = -12
y = 11
Step-by-step explanation:
i used substitution and let 'x' = 10 - 2y
3(10 - 2y) + 4y = 8
30 - 6y + 4y = 8
30 -2y = 8
-2y = -22
y = 11
x + 2(11) = 10
x + 22 = 10
x = -12
