The total amount paid in monthly payments is found by multiplying $70 by 10. This is the only information that is needed to find the amount paid over 10 months.
70 x 10 = $700
Ennifer will pay $700 in monthly payments.
Angle a is 90 and angle b is the difference of 180 - 163, or 17

2)probability of showing its heads is 1/2
Answer:
- 15 = -3c +12
- -3n +8 = -7
- 5z -40 = 10
- 3.4s -35 = 50
Step-by-step explanation:
Usually, you're asked to "simplify" an equation, meaning that you eliminate parentheses and combine like terms. Asking for "simplest form" suggests something different. The simplest form is the form that has the variable equal to a constant--the solution, in other words.
We suspect you want the <em>simplified form</em>, but since you asked for the <em>simplest form</em>, that is here, too.

1. 15=-3(c-1)+9
15 = -3c +3 +9
15 = -3c +12 . . . . . simplified form of the given equation
-1 = c . . . . . . . . . . "simplest" form
