Maria brought $50 to spend on rides at the

1 answer:

4 0

She has paid for 11 rides.

She started with 50 dollars and at the end she has 6 dollars left. Each ride costs 4 dollars. The follow equation could be created:

$6 = $50 - $4r

Six dollars remaining = original fifty dollars - four dollars per ride.

The number of rides is represented by the variable r.

To solve:

$6 = $50 - $4r
Subtract 50 from both sides

-$44 = -$4r.
Divide each side by -4 to get the number of rides (r)

11 = r

Therefore, she has paid for 11 rides.

denpristay [2]

Answer:

12.76

Step-by-step explanation:

This is much easier to solve if you draw it out on a graph. The perimeter is the sum of all the sides. I used the Pythagorean theorem to find the hypotenuse.

${a}^{2} + {b}^{2} = {c}^{2} \\ c = \sqrt{ {a}^{2} + {b}^{2} }$

$dc = \sqrt{ {3}^{2} + {1}^{2} } = \sqrt{10} \\ cf = 1 \\ fe = \sqrt{ {4}^{2} + {2}^{2} } = \sqrt{20} \\ de = \sqrt{ {1}^{2} + {4}^{2} } = \sqrt{17} \\ \sqrt{10} + 1 + \sqrt{20} + \sqrt{17} = 12.76$

What is the value of y in the equation 5x+2y=20, when x=0.3

Rasek [7]

5x+2y=20

Substitute 0.3 for x

5(0.3)+2y=20

Multiply 5 by 0.3

1.5+2y=20

Subtract 1.5 from both sides

2y=18.5

Divide 2 on both sides

Final Answer: y= 9.25
