Answer:
1. The equation that represent the distance (d) that a person can run in t hours is: d = 4t
2. The equation is: c = $0.98(20)
3. The equation is: L = 18(5)
Step-by-step explanation:
1. The variable d represents the distance over time, and t represents the hour in the equation so if you want to find the distance over time, you would say distance per hour. The per means to multiply, so every distance is equal to 4 miles per hour..
2. If the teacher wants to find out how much she will have to pay for 20 chocolate bar, she has to substitute 20 into the equation to replace b, which means bar. So the equation would be: total cost (c) = $0.98 × chocolate bars (b). Once substituted, the equation will be c = $0.98(20).
3. The problem said "mows 18 lawns per day" and "mow in 5 days", that means that you substitute 5 into the equation to replace the d in days, since you are multiplying 5 × 18.. Your new equation will be: L = 18(5), Total Lawns = 18 (lawns) per 5 (days).

Answer:
$38.69
Step-by-step explanation:
To find the regular price, create a proportion.

3289=85x
38.69 = x
The least common multiple for four and six is, one.
Answer:
The answer is option is C
Step-by-step explanation:
In this problem we have a couterclockwise about the origin
sp
Verify
Option D
rotation 90 degrees counterclockwise
(x,y) -------> (-y,x)
so,
A(-2,3) ---------> A'(-3,-2) ---------> is not ok
therefore, the answer is option is C
