Jon has to pay $7.00 admission for the skating rink in $1.50 per hour to rent rollerblades. How many hours can he skate for $19?
eduard

Answer: 8 hours

Step-by-step explanation:

<u>Given information</u>

Admission fee = $7.00

Hour rent fee = $1.50

Number of hours = h

Total fee = $19

<u>Set equation according to the given information</u>

Total fee = admission fee + (hours) × (hour rend fee)

<u>Substitute values into the equation</u>

19 = 7 + 1.5h

<u>Subtract 7 on both sides</u>

19 - 7 = 7 + 1.5h - 7

12 = 1.5h

<u>Divide 1.5 on both sides</u>

12 / 1.5 = 1.5h / 1.5

\boxed{h=8}

Hope this helps!! :)

Which expression is equivalent to 9^3/3^3
Allisa [31]

Answer:

3^3

Step-by-step explanation:

Exponents

9^3 can be rewritten as

3^2 ^3

Using exponent rules a^b^c = a^ (b*c)

3^2^3 = 3^6

3^6 / 3^3

We know that a^b / a^c = a^(b-c)

3^6 / 3^3  = 3^(6-3) = 3^3

Quadratic equations Please Help Me!!!!!!
igor_vitrenko [27]

The roots are 1 +√7 and 1 -√7.

<h3>What is Quadratic equation?</h3>

A quadratic equation in the variable x is an equation of the form ax² + bx + c= 0, where a, b, c are real numbers, a≠0

Given equation:

y= x²+2x-6

First,

Half the coefficient of x and add and subtract the square of (b/2)

y= x²+2x-6+(1)²-(1)²

y= x²+2x+(1)² -6 -(1)²

y= (x+1)² -7

Now, equate y=0

(x+1)² -7 =0

(x+1)² = 7

x+1= ±√7

x=1 ±√7

Hence, the roots are 1 +√7 and 1 -√7.

Write the equation of the line in either point-slope form or slope-intercept form.
DedPeter [7]

Answer:

y = -3x + 0.25

Step-by-step explanation:

A line has the following slope-intercept equation:

y = ax + b

In which a is the slope.

Write the equation of a line that has a slope of -3 and passes through the point (1.25, -4).

Slope of -3 means that a = -3. So

y = -3x + b

Passes through the point (1.25, -4). Means that when x = 1.25, y = -4

-4 = -3*1.25 + b

b = -3*1.25 + 4

b = 0.25

So

y = -3x + 0.25

Find "G". Round to two<br>decimal places.<br>G= R+ab/at<br>R=257<br>a=4.88<br>b=37.4<br>t=61.5​
givi [52]

Answer:

G ≈ 1.46

Step-by-step explanation:

Given

G = \frac{R+ab}{at} , substitute values

G = \frac{257 4.88(37.4)}{4.88(61.5)}

   = \frac{257+182.512}{300.12}

   = \frac{439.512}{300.12} ≈ 1.46 ( to 2 dec. places )
