6 0

Answer:

38.5

Step-by-step explanation:

Lets say, first number = x



Second number = 3x+7



Total = 49




(x)+(3x+7)= 49



4x+7 = 49



4x = 42



x = 42/4



x= 10.5




x= 10.5



3x+7 = 3(10.5)+7 = 38.5




Hope this helps!!

Jason's business computers need servicing. The expression 81x + 108 represents a contractor's total charges in dollars for fixin
Zielflug [23.3K]

Answer:

The Jason's company charges more than the contractor's company.

Step-by-step explanation:

There are two expressions given for total charges for two companies as 81 x+108 and 103 x+64.

Here x represents number of hours.

We are asked to find difference in total charges if that takes 45 minutes.

45 minutes = \frac{3}{4} hours.

Plug in this value for x.

81x+108 =81*\frac{3}{4} +108

Simplify it

60.75 +108 =168.75

Now, for 103x+64 =103 *\frac{3}{4} +64

Simplify it,

77.25+64=141.25

If we see the total charge for both companies for 45 minutes, the Jason's business computers charges more than contractor's company.

A typical marathon is 26.2 miles. Allan averages 12 kilometers per hour when running in marathons. Determine how long it would t
Natali [406]

Answer:

The time taken by Allan to complete the marathon 3.5 hours

Step-by-step explanation:

Given as :

The distance cover in marathon = d = 26.2 miles

∵ 1 mile = 1.609 km

So, d = 26.2 × 1.609 km

i.e d = 42.155 kilo meter

The average speed of Allan = s = 12 km per hour

Let the time taken by Allan to complete the marathon = t hours

Now, ∵ Time = \dfrac{\textrm Distance}{\textrm Speed}

Or, t =  \dfrac{\textrm d}{\textrm s}

Or, t =  \dfrac{\textrm 42.155 km}{\textrm 12 kmph}

or, t = 3.512 hours

So , The time taken by Allan to complete the marathon = t = 3.5 hours

Hence, The time taken by Allan to complete the marathon 3.5 hours Answer
