Step-by-step explanation:
(a)
10x - 45 ← factor out 10 from each term
= 10(x - 4.5)
(b)
- 2x + 3 ← factor out - 2 from each term
= - 2(x - 1.5)
(c)
- x + 4 ← factor out - 1 from each term
= - 1(x - 4)
(d)
- x - 19 ← factor out - 1 from each term
= - 1(x + 19)
Congruent means they are the same,
A and Q are both the first letters, which mean they would also be the same.
Set the two equations equal to each other, solve for x then solve for angle A.
x-10 = 2x-30
Add 30 to each side:
x+20 = 2x
Subtract 1x from each side:
x = 20
Now replace x with 20 in the equation for A
A = 20-10
Angle A = 10 degrees.

Answer:
Step-by-step explanation:
Plan A = 30 +0.15x
Plan B = 16 +0.20x
30+0.15x = 16+0.20x
subtract 16 from each side
14 +0.15x = 0.20x
subtract 0.15x from each side
14=0.05x
x = 14/0.05 = 280 minutes
280*0.15 = 42 +30 = $72
280 * 0.20 = 56 +16 = 72
280 minutes and cost $72 each
