Answer:

4500 feet

Step-by-step explanation:

Unit Conversion used:

1 yard = 3 feet

Unit multipliers used:

$(30 laps)/(1 week)$

$(25 yards)/(1 lap)$

$(3 feet)/(1 yard)$

The unit multipliers are set up in such a way that when they are multiplied with eachother, the initial unit of “weeks” gets cancelled out and the final answer is assigned the units of “feet”

∴Total distance he swam during = $(2 weeks)$ × $((30 laps)/(1 week))$ × $((25 yards)/(1 lap))$ × $((3 feet)/(1 yard))$

hiswinter break = 4500 feet

Hi there!

Great question! :D

To figure out our unknown value, we can replace our unknown value, or blank space, with x.

So our equation would look something like $4x = 30$

We have a variable next to a number to show we are multiplying. But since we're figuring out an unknown, we'll do the opposite, which is division.

$4x = 30$

We'll divide both sides by our 4.

$(4x)/(4) = (30)/(4)$

We can eliminate the variable right away on our left side of our equation. This makes it look like there's not a lot of steps through solving.

$(30)/(4) = 7.5$

Final answer:

$x = 7.5$

When in doubt of your answer, we can multiply 4 by 7.5 and see what we get. We should get 30.

$4 * 7.5 = 30 :)$

We were right!

Hope this helps! :D

4x=30
4x/4=30/4
x=7.5

Hope this helps!!

The equation y = 55x + 85 describes the amount of money a plumber charges, where y is the total amount he charges and x is the number of hours he works. The table shows the total amount of money an electrician charges.How much does each charge per hour?

Number of hours worked 1 2 4 7
Total amount charged 115 180 310 505

the plummer charges $___ per hour
the electrician charges $___ per hour

Answers

If you would like to know how much does each charge per hour, you can calculate this using the following steps:

x ... the number of hours
a plumber: y = 55x + 85 = 55 * 1 + 85 = 55 + 85 = $140 per hour
an electrician: y = $115 per hour

The correct result would be: the plumber charges $140 per hour and the electrician charges $115 per hour.
