Answer:

the rates are equivalent.

Step-by-step explanation:

liam practiced piano 24 times in 4 weeks.

1 week = 7 days

4 weeks = 28 days

liam practiced piano 24 times in 7 days

The ratio of 24 times to 7 days is \frac{24}{28}= \frac{6}{7}

his brother practiced piano 12 times in 14 days.

The ratio of 12 times in 14 days is \frac{12}{14}= \frac{6}{7}

Both the fractions are equivalent

So the rates are equivalent.

Yes because if you simplify 24 and 4 weeks(28 days) by 2 than you would get 12 and 2 weeks(14 days)

Pamela drove her car 99 kilometers and used 9 liters of fuel. She wants to know how many kilometers, (k), she can drive with 12
solong [7]
99 km ... 9 liters
x km   ... 12 liters

If the relationship is proportional, we have

\frac{99}{x} = \frac{9}{12}

from where 

x =  \frac{99*12}{9}= \frac{1188}{9}=\bold{132}

The answer is 132 kilometers.

777dan777 [17]
<h3>Answer ↓</h3>

option B.

Calculations ↓

First, let's think of two numbers so that :

  • if we multiply these numbers, we'll get 4
  • if we add these numbers, we'll get 5

These numbers are :

4 and 1

Plug these numbers here :

(x+4) (x+1)

So the correct factored form of this expression is

Option B) (x+4)(x+1)
