Bobby catches 8 passes in 3 football games. At this rate how many passes dose he catch in 15 games?expine
stepan [7]

Answer: 40

Step-by-step explanation:

I can see the answer is 40, but let's try to figure out how to do it.

I like to use the rule of 3. Let's put the number of passes on the left side and the number of games on the right side.

\frac{8}{x}=\frac{3}{15}

''x'' represents the number of passes in 15 games.

Solve for x;

x=\frac{15*8}{3}\\ x=\frac{120}{3}\\ x=40

irakobra [83]
If a plane flies an average of 325 miles per hour, to find out 7 hours you will need to times 325 by 7. 
325 x 7 = 2275. 
therefore the flight for 7 hours was 2275 miles.

Solve the equation: -6p + 14 and 3p - 2
sleet_krkn [62]

Answer:

p = 16/9

Step-by-step explanation:

-6p+14=3p-2\qquad\text{subtract 14 from both sides}\\\\-6p=3p-16\qquad\text{subtract 3p from both sides}\\\\-9p=-16\qquad\text{divide both sides by (-9)}\\\\\boxed{p=\dfrac{16}{9}\to p=1\dfrac{7}{9}}

Santino bought a book for $23.54. The price of the book was $22. What was the sales-tax rate?
Vika [28.1K]

We first find value of tax in dollars.

The difference between the two prices  is: 23. 54 - 22 = 1.54

Therefore the sales tax in dollars is 1.54

The tax % will be  (amount of tax / original cost price ) × 100

(1.54 / 22) × 100 → (0.07) × 100 =  7

So the tax rate is 7%

We can double check the answer.

7 % of 22  → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54
