Two thirds equals 18 over x plus 5

Wewaii [24]

Problem: 2/3= 18/(x+5)

First, I would multiply the (x+5) over

Making it 2/3(x+5)=18

Second, I would Divide by 2/3 (which is the same as multiplying by the reciprocal 3/2)

which shows up like this now (x+5)=18*3/2

third I would subtract the 5 over

which will give you your answer

This question is confusing. Please help me!

patriot [66]

Answer:

C. 490.

Step-by-step explanation:

25% = 0.25.

If the number of emails that Ryan and Taylor each received is x emails then Sara received 2x + 0.25 * 2x = 2.5 emails.

So 2x + 2.5x = 882

x = 882/4.5

x = 196.

So Sara received 2.5 * 196

= 490 emails.

The video club to which Lin belongs allows her to receive one free DVD for every three DVDS she rents. If she pays $3 for each D

Nesterboy [21]

Answer:

Step-by-step explanation:

Given:

On every 3 DVDs she rents, 1 DVD is received for free

Rent of each DVD = $3

Total amount paid = $114

Now,

The total number of DVDs she took on rent = $\frac{\textup{Total amount paid}}{\textup{Rent of each DVD}}$

The total number of DVDs she took on rent = $\frac{\textup{114}}{\textup{3}}$

The total number of DVDs she took on rent = 38

also,

For every 3 DVDs she gets 1 Free DVD

thus,

For every 1 DVD she gets $\frac{\textup{1}}{\textup{3}}$ free DVD

therefore,

For 38 DVD she gets $\frac{\textup{38}}{\textup{3}}$ free DVD

she gets 12.67 DVDs free

Since,

the DVDs cannot be given in fraction

Hence she will get 12 free DVDs

Pick the description of a geometric object that best matches the real-world object:<br><br> tent

Elodia [21]

Answer:

Triangular Prism

Step-by-step explanation:

We are given the object 'Tent' and are required to find a 3D object resembling it.

Since, the object represents a tent. So, it must have two similar and parallel bases with parallelograms as sides.

Therefore, we get that the 3D object that resembles a tent is a 'Triangular Prism'.

A triangular prism has two similar triangular bases and three rectangular sides as shown in the figure below.

Hence, 'Triangular Prism' is the answer.
