1, 2, 3, or 4? Thanks :)
Answer:
solve the equation 3c-4=17
choice 4
Step-by-step explanation:
3c-4=17
3c=17+4
3c=21
3c÷3=21÷3
c=7

Answer:
Step-by-step explanation:
Let a represent the length of board a.
Let y represent the length of board b.
The total length of both is 28 feet. This means that
a + b = 28
Board b is at least 5 feet longer than board a. This means that
b ≥ a + 5
The difference between both boards is not more than 12 feet. This means that
b - a < 12
Substituting a = 28 - b into b ≥ a + 5, it becomes.
b ≥ 28 - b + 5
b ≥ 28 - b + 5
2b ≥ 28
b ≥33/2
b ≥ 16.5
16.5 - a < 12
4.5 < a
a > 4.5
The possible lengths of board a is
8 to 11.5 feet
The possible lengths of board b is
16.5 to 20 feet
The salestax on an item that is 25.60 dollars is 1.325 dollars.
A fraction is written in the form of p/q, where q ≠ 0.
There are two types of fractions one is a proper fraction and another one is an improper fraction.
In proper fractions, the numerator is smaller than the denominator and in improper fractions, the numerator is greater than the denominator.
Given, sales tax for a certain state can be found by multiplying the purchase price by 1/20.
∴ Sales tax on an item that is 25.60 is 25.60×1/20.
= 1.325 dollars.

B.) t + b less than or equal to 20 15t + 8b greater than or equal to 150
C.) t + b less than or equal to 20 15t + 8b less than or equal to 150
D.) None of the systems shown represent this scenario.
Answer:
Option B is the correct answer.
Step-by-step explanation:
Earning for tutoring per hour = 15$
Earning for bag boy per hour = 8$
We have Nick is only able to work up to 20 hours per week but must earn at least $150 per week and t represents the number of hours Nick tutors and b represents the number of hours he works as a bag boy.
Nick is only able to work up to 20 hours per week
t + b ≤ 20
But must earn at least $150 per week
15 t + 8 b ≥ 150
Option B is the correct answer.
