olga2289 [7]

Is means equal in mathematics
of means multiplication
and if we are solving for x then we can translate your equation to:

$\sf{x=\frac{1}{4}\times\frac{1}{12}}$

Simplifying that more, we get:

$\sf{x=\frac{1}{48}}$

And your final answer is:

$\huge{\boxed{\bf{\frac{1}{48}~is~\frac{1}{4}~of~\frac{1}{12}}}}$

Answer:

Ok so you have to figure out what is the input, output, y-intercept (b), slope (m), and equation.

First, input is the x. Looking at the graph.

Input : 0, 10, 20

Second, output is the y. Looking at the graph.

Output : 20, 30, 40

Third, y-intercept is the b in the equation of y = mx + b. Looking at the graph.

Y-intercept (b) : 20

Fourth, slope is the m in the equation of y = mx + b. Looking at the graph.

Slope (m) : 1/2

Fifth, you have to find the equation in the form of y = mx + b. Looking at the graph.

Equation : y = 1/2x + 20

I hope this helps and if you have any other questions I would be glad to answer it, thank you :) !!

A Jet ski rental company charges a one time fee of $50 , and $90 per hour to rent one of their jet skis. How many hours (X) it w

AleksandrR [38]

Answer:

24 hours

Step-by-step explanation:

Given that:

One time fee for renting the Jet ski = $50

Per hour charges to rent one Jet ski = $90

Total money available = $2210

To find:

Number hours $X$ it will take to spend the total money.

Solution:

Charges for renting the jet ski for one hour = $90

Charges for renting the jet ski for $X$ hours = $90 $X$

As per question statement, it can be written that:

One time Charges + Charges for renting the jet ski for $X$ hours = $2210

$\Rightarrow 50 + 90X=2210\\\Rightarrow 5+9X=221\\\Rightarrow 9X=216\\\Rightarrow X =\bold{24\ hours}$
