3.5m + 2.5 = 79.5 is the equation that could be used to determine m, the number of miles in the taxi ride.

Given in question,

Pick-up fee = $2.50

Fee per mile = $3.50

Total fare = $79.50

Let the no. of miles = m

Fee for m miles = 3.50m

Equation, 3.50m + 2.50 = 79.50.

Hence, the equation is 3.50m + 2.50 = 79.50.

Oksanka [162]

Answer:

6,226 tiles of 9 in are needed to cover an area of 400 square feet

Step-by-step explanation:

Let

A -----> an area in square feet

t(A) ---> the total number of 9 in. tiles needed

we have

$t(A)=\frac{144A}{9.252}$

For A=400 ft^2

substitute in the equation and solve for t

$t(400)=\frac{144(400)}{9.252}$

$t(400)=6,226\ tiles$

That means -----> 6,226 tiles of 9 in are needed to cover an area of 400 square feet

Kevin and Randy Muise have a jar containing 80 coins, all of which are either quarters or nickels. The total value of the coins

SCORPION-xisa [38]

Answer:

39 quarters and 41 nickels

Step-by-step explanation:

Let the number of quarters be x and nickels be y.

Given:

Quarter is 25 cents
Nickel is 5 cents
Number of coins is 80
Total amount is $11.80 = 1180 cents

We have equations:

x + y = 80
25x + 5y = 1180

Solve the system by elimination, subtract 5 times the first equation from the second one:

25x + 5y - 5x - 5y = 1180 - 80*5
20x = 780
x = 780/20
x = 39

Find the value of y:

39 + y = 80
y = 80 - 39y = 41

Verify:

25*39 + 5*41 = 975 + 205 = 1180
