The equation y=3.2x represents the cost y (in dollars) for a taxi ride during peak hours that costs x dollars during off-peak ho

____ [38]

Answer:

x = y / 3.2

Step-by-step explanation:

Given:

y = 3.2x

Where

y = cost for a taxi ride during peak hours (in dollars)

x = cost for a taxi ride during off-peak hours (in dollars)

Solve the equation for x.

y = 3.2x

Divide both sides by 3.2

y / 3.2 = 3.2x / 3.2

y / 3.2 = x

x = y / 3.2

This means,

Cost for a taxi ride during off-peak hours (in dollars) = Cost for a taxi ride during peak hours (in dollars) / 3.2

Mount everest is 8847 m high. how many centimeters high is the mountain

nata0808 [166]

Before we answer the question we must first:
1. Assess what we have so far.
2. Know what we need to find.
3. Solve.
4. Conclude.

Step 1: What we have so far.
*Mt. Everest's height in meters (m) = 8847m

Step 2: What we need to find.
*Mt. Everest's height in centimeters (cm) = ?

Step 3: Solve.
*Centi means 100.
*1m = 100cm

Conversion process:
8847m x 100cm/1m <--- we need to multiply Mt. Everest's height to 100cm/1m first because our first agenda is to remove (m) from the value.
8847 x 100cm <--- this will be our working solution.
884,700cm <--- Answer

Step 4: Conclusion.
After successfully doing the steps above, we can now conclude that the height of Mt. Everest in centimeters is: 884,700cm

Pre-orders for the yearbook cost $38 each and full price cost $45 each. If 24 students in Mr. Hillman's class purchased yearbook

aleksandr82 [10.1K]

15 students preordered the year book and 9 students paid full price.

Solution:

Given that

Cost of pre-ordered year book = $\$38$ each

Cost of full price of year book = $\$45$ each

Number of students in Mr. Hillman's class purchased yearbooks = 24

Total price spent by 24 students to purchase year book = $\$975$

Need to determine number of students pre-ordered and number of students paid full price.

Let assume number of student pre-ordered year book = x

As out of 24, x students pre-ordered the yearbook , so remaining are the ones who paid full price

So number of students paid full price = $24-x$

Money spent by students who pre-ordered the book = number of student pre-ordered year book multiplied by Cost of 1 pre-ordered year book = $x\times38 = 38x$

Money spent by students who paid full price = number of students paid full price x Cost of 1 full price year book = $(24-x)\times 45 = 1080-45x$

Total price spent by 24 students to purchase year book = Money spent by students who pre-ordered the book + Money spent by students who paid full price

$\Rightarrow 975=38 x+1080-45 x$

On solving above expression for x, we get

$\begin{array}{l}{\Rightarrow 975-1080=38 x-45 x} \\\\ {\Rightarrow-105=-7 x} \\\\ {\Rightarrow \frac{-105}{-7}=x} \\\\ {\Rightarrow x=15}\end{array}$

Number of student pre-ordered year book = $x=15$

Number of students paid full price = $24-x = 24-15 = 9$

Hence 15 students pre-ordered the year book and 9 students paid full price.
