Question

a pet store has 65 fish tanks. each tank has f fish. using f, write an expression for the total number of fish in the store.
65 - f
\\(\frac{65}{f}\\)
65f
65 + f
question 2
jorges is saving money. he started with $15 and deposits $45 each month into a savings account. which equation can be used to determine how many months, x, it will take jorge to save $165?
15x - 45 = 165
45x - 15 = 165
15x + 45 = 165
45x + 15 = 165
question 3
mavis is driving at a speed of 62 mph. how many hours does it take her to drive 465 miles? express your answer as a number to the nearest tenth.
_____ hours

Explanation:

Question 1

Step1: Define total fish count

Total fish = tanks × fish per tank

Step2: Substitute given values

Total fish = $65 \times f = 65f$

Question 2

Step1: Define total savings

Total = initial + monthly deposit × months

Step2: Substitute given values

$165 = 15 + 45x$ or $45x + 15 = 165$

Question 3

Step1: Recall time-distance formula

Time = $\frac{\text{Distance}}{\text{Speed}}$

Step2: Substitute given values

Time = $\frac{465}{62}$

Step3: Calculate and round

$\frac{465}{62} \approx 7.5$

Answer:

1. $\boldsymbol{65f}$
2. $\boldsymbol{45x + 15 = 165}$
3. $\boldsymbol{7.5}$ hours
