If the equal is 55x + 35y = 200

x: time-driven at 55 miles/hour

y: time-driven at 35 miles/hour

If the car spends 2.5 hours at 35 miles per hour, then it drove:

 55x + 35(2.5) = 200

    55x =35

       y = 112.5

There the drive spent about 2.5-hour driving at 55 mph.

Hope it helps!

Find the distance, c, between (2,-1) and (-1, 4) on the coordinate plane. Round to the nearest tenth
Fynjy0 [20]

Answer:

c ≈ 5.8 units

Step-by-step explanation:

Calculate c using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (2, - 1 ) and (x₂, y₂ ) = (- 1, 4 )

c = \sqrt{(-1-2})^2+(4-(-1))^2

   = \sqrt{(-3)^2+(4+1)^2}

   = \sqrt{9+5^2}

    = \sqrt{9+25}

    = \sqrt{34}

    ≈ 5.8 units ( to the nearest tenth )

10. Daniels goes to the shopping center. He has a bank account with a
Savatey [412]

Answer:

-$36

Step-by-step explanation:

Daniel has a starting balance of $259, so anything he spends will be deducted by this amount. To find out how much he spent, we need to add up everything he bought.

He spent $45 + $150 + $100, adding to a grad total of $295.

To find out how much money Daniel has left, we need to subtract his purchases from his funds. This would be $259 - $295. This leaves you with a final answer of -$36 in Daniel's bank account.

Mike has a total of 25 dimes and nickels. If the total value of the coins is $1.90 how many of each coin does he have? ​
bezimeni [28]

Answer:

12 nickels and 13 dimes

Step-by-step explanation:

d = # of dimes

n = # of nickels

Set up a System of Equations as follows:

d + n = 25

.10d + .05n = 1.90

now solve for 'd' or 'n' and use Substitution:

d = 25-n

.10(25-n) + .05n = 1.90

2.5 - .10n + .05n = 1.90

-.10n + .05n = -0.6

-.05n = -0.6

n = -0.6/-.05

n = 12

d + 12 = 25

d = 13

Check:   12(.05) + 13(.10) should equal 1.90

0.60 + 1.30 = 1.90

1.90 = 1.90
