What is the answer to this 14-2y=​

Mathematics
1 answer:
yaroslaw [1]3 years ago
4 0

Answer:

y=7

Step-by-step explanation:

Assuming that the equation is 14-2y=0

We need to isolate 'y' variable to obtain its value, to do that, lets start by subtracting -14 to both sides of equality sign,

14-2y=0 is now this: 14-14-2y=0-14, which is equals to -2y=-14

Now, lets continue by dividing by -2 both sides of equality sign.

We have this

-2y/-2=-14/-2

y=7

Thus, we've obtained the value for 'y' variable

A tent was marked up 150% from an original cost of $52. Last Friday, Ethan bought the tent and paid an additional 10% in sales t
Savatey [412]

Answer

Find out the  what was his total cost .

To prove

As given

A tent was marked up 150% from an original cost of $52.

Last Friday, Ethan bought the tent and paid an additional 10% in sales tax.

Than the equation becomes

150 % is written in the decimal form .

=\frac{150}{100}

= 1.5

10 % is written in the decimal form .

=\frac{10}{100}

= 0.1

cost of the tent when 150% marked up from origianl price = 1.5× 52

                                                                                                = $ 78


cost of the tent = origianl cost + 150% marked up from origianl price

                                  =  $52 + $78

                                  = $ 130

Sales price on the tent = $130 × 0.1

                                      = 13

Total cost of the tent = $130 + $13

                                  = $143

Therefore the cost of the tent is $143.

1/2 ⇒ 0.5
2/3 ⇒ 0.66
2/5 ⇒ 0.4
3/4 ⇒ 0.75

Now it's easy to order the numbers from least to greatest.

First order the decimals.

0.4, 0.5, 0.66, 0.75

Now order them with their corresponding fractions.

2/5, 1/2, 2/3, 3/4 is your answer.
