Answer:
Step-by-step explanation:
If A is parallel to B, then angles 2 and 4 are same side interior and they are supplementary. Thus,
2x + 10 + 4x + 80 = 180 and
6x = 90 so
x = 15
Answer:
x/4+13
Step-by-step explanation:
Answer:
$85
Step-by-step explanation:
Let y represent Timmy's money after x weeks. If we assume that the only money Timmy has is what is mentioned in the problem statement, then ...
y = 50 +5x . . . . . $50 initially plus $5 for each week
After 7 weeks, x = 7, so Timmy's fortune will be ...
y = 50 +5(7) = 50 +35
y = 85
Timmy will have $85 in 7 weeks.
