When Imani walks to school, it takes her one less minute than five times the amount of time it takes her to ride her bike to sch
zmey [24]

The numerical expression that describes the amount of time it takes Imani to walk to school is x = 5y - 1.

<h3>How do we derive a numerical expression?</h3>

Let:

x = amount of time it takes Imani to walk to school

y = amount of time it takes Imani to ride to school = 3 minutes

The numerical expression that describes the amount of time it takes Imani to walk to school can be written as follows:

x = 5y - 1

Since it takes Imani three minutes to ride her bike to school, we can solve for x by substituting y = 3 as follows:

x = (5 * 3) - 1 = 15 - 1 = 14 minutes

Solve for the missing variable.<br> 1.)<br> 80/120 =2/x
crimeas [40]

Answer:

x = 3

Step-by-step explanation:

\frac{80}{120} = \frac{2}{x}

Simplify, divide the numerator and denominator by the same number

\frac{80}{120}\\

÷ 40

\frac{2}{3}

\frac{2}{3} = \frac{2}{x}

Cross products

2x = 2 *3\\2x = 6\\/2    /2\\\\x = 3

Factor out 1/4 out of 1/4x+11/4
cluponka [151]

\frac{1}{4} x+\frac{11}{4}

we can rewrite it as

\frac{1}{4}* x+\frac{1}{4}*11

we can see that 1/4 is in multiple in both terms

so, we can factor it out

so, we get

\frac{1}{4}( x+11)..............Answer
