Liula [17]

Answer:

The number of months  does the lease last are 36 months.

Step-by-step explanation:

Let us assume that the number of months be x.

As given

Taylor Scuff leased a new sports car and is certain she can keep under the 12,000 miles allowed a year.

The $2,200 due at signing includes the title and license fee.

Her monthly lease payments are $700 a month.

If the total lease cost is $27,400.

Than the equations becomes

2200 + 700x = 27400

700x = 27400 - 2200

700x = 25200

x = \frac{25200}{700}

x = 36

Therefore the number of months  does the lease last are 36 months.

A recipe calls for 4cups of flour for 12
Dmitriy789 [7]

Answer:

15 muffins

Step-by-step explanation:

We can use proportion to solve this.

Let x be the number of muffins that can be made with 5 cups of flour

4 cups = 12 muffins

5 cups =   x

cross-multiply

4×x = 12 × 5

4x = 60

Divide both-side of the equation by 4

\frac{4x}{4}  =  \frac{60}{4}

(On the left-hand side of the equation, 4 on the numerator will cancel-out 4 on the denominator, while on the right-hand side of the equation 60 will be divided by 4)

x = 15 muffins

15 muffins can be made with 5 cups of flour.

\bf \begin{array}{ccll} cans&\$\\ \cline{1-2} 12&33\\ 5&x \end{array}\implies \cfrac{12}{5}=\cfrac{33}{x}\implies 12x=165 \\\\\\ x=\cfrac{165}{12}\implies x=13.75
