Answer:
The equation that models the amount of money she could raise is written as:
t = 25c
Step-by-step explanation:
Rachel is selling gift cards to raise money for her swim team. Each gift card costs $25.00. If c represents the number of gift cards she sells, , which equation models the amount of money she could raise?
Let t represent the total amount collected
Each gift card costs $25.00.
If c represents the number of gift cards she sells
The equation that models the amount of money she could raise is written as:
t = $25 × c
t = 25c
12x-9-3x=72
9x-9=72
9x-9+9=72+9
9x=81
9x/9=81/9
x=9
Answer:
C

The square root of 50 is 7.07
Answer:
9/41
Step-by-step explanation:
Cosine represents adjacent / hypotenuse.
When A is the reference angle, AB is the adjacent side (9) and AC is the hypotenuse (41).
9/41 is already simplified.
Answer:
C. -2n² - n + 5
Step-by-step explanation:
In expression C, the coefficient of the n term is -1;
The expression in choice C is given as:
-2n² - n + 5
The coefficient is the number before a variable;
For n², the coefficient is -2
for n, the coefficient is -1
