B, C, and D all have an x-value of 4.
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:
729015430.40641995 = 729015430.41
Step-by-step explanation:
Since the 3 decimal place is 6, you round up. If you round up for 0 you get 1. Therefore your answer is 729015430.41.
Answer:
1) 6 (9x - 5)
2) 4 (1 + 6)
Step-by-step explanation:
<u>1.</u>
54x - 30
The greatest common factor is 6, hence take out 6
6 (9x - 5)
<u>2.</u>
4 + 24
The greatest common factor is 4, take out 4
4 (1 + 6)
*I am not simplifying this because as per what is given, I am unsure if one of these numbers is actually a coefficient.
