Kenya plans to make a down payment plus monthly payments in order to buy a motorcycle. At one dealer she would pay $2,350 down a

vovangra [49]

Answer:

After 16 months, Kenya will have paid $5,550

Step-by-step explanation:

This is a guess and check type of a problem. You guess a number of months, plug it into x, and see if both equations come out with the same answer.

If you plug 16 into the first dealer's equation, you get y= 200(16) + 2350. Solving this equation will mean y equals 5550.

If you plug 16 into the second dealer's equation, you get y= 175(16) + 2750.

Solving this equation will mean y also equals 5550.

A regular hexagon has an apothem measuring 14 cm and an approximate perimeter of 96 cm.

Mariulka [41]

ANSWER

672cm²

EXPLANATION

The area of a regular hexagon is given by the formula,

$Area = \frac{1}{2} ap$

where a=14cm is the apothem and p=96cm is the perimeter of the regular hexagon.

We substitute the values into the formula,

$Area = \frac{1}{2} \times 14 \times 96 {cm}^{2}$

$Area =672 {cm}^{2}$

Therefore the approximate area of the hexagon is 672cm²

Can someone help me please i need to get this right

mixer [17]

Answer:

If there are 2 quarters for every 3 nickels,

then there are $45*\frac{2}{3} =30$ quarters.

If there are 2 dimes for every quarter,

then there are $30*2=60$ dimes.

If the number of pennies and nickels together are equal to the number of dimes, then there are $60-45=15$ pennies.
