Answer:
c. 42 miles per day
Step-by-step explanation:
From the information given, you can use a rule of three to calculate the constant rate that Kendra swims per day given that she swims 126 miles in 3 days:
3 days → 126 miles
1 day → x
x=(1*126)/3=42 miles
According to this, the answer is that Kendra swims 42 miles per day.
Sorry I don't know that either
Answer:
<u><em>A</em></u>
Step-by-step explanation:
<u>a)</u>
<u></u>
<u></u>
<u>8(9) / 9 = 8 x 7 = 56</u>
b)
2(9) * 3 - 12
18 * 3 = 54 - 12 = 42
c)
4(9) - 18 + 12
36 - 18 = 18 + 12 = 30
d)
21 + 24 = 45
8.5x + 55 = 123
You would use the formula: mx + b = y
The slope is the amount of money each day(mx),and the y-intercept would be the fee(b) and the total cost would be y.
