Solve the equation 3x + 5y = 15 for y.

1 answer:
Naddika [18.5K]3 years ago

Answer:

y=\frac{-3}{5}x+3

I don't see this in any of your choices.

Please be sure the problem and choices are as you want them to be seen by others. Thanks kindly.  

I do hope my answer is helpful.

Step-by-step explanation:

3x+5y=15

We want to get the term that contains y by itself.

This means we want to get 5y by itself first.

To do this I need to get rid of the plus 3x on that side.

I will do the inverse operation of that; I will subtract 3x on both sides.

3x+5y=15

-3x             -3x

5y=15-3x

5y=+15-3x

5y=-3x+15 since addition is commutative.

Now we have the 5y term by itself. We want the factor y in 5y by itself.

To undo multiplication you must divide.  We will divide both sides by 5:

5y=-3x+15

------------------------------

            5

\frac{5y}{5}=\frac{-3x+15}{5}

y=\frac{-3x}{5}+\frac{15}{5}

y=\frac{-3}{5}x+3

Angle Addition Crossword
Elena-2011 [213]

Answer:

Step-by-step explanation:

1). m∠AEC = m∠AEB + m∠BEC

                  = 21° + 37°

                  = 58°

2). m∠BED = m∠BEC + m∠CED

                   = 37° + 44°

                   = 81°

3). m∠IKF = m∠IKH + m∠HKG + m∠GKF

                = m∠IKH + m∠HKG + m∠IKH [Since, ∠IKH ≅ ∠GKF]

                = 2∠IKH + m∠HKG

         103° = 2∠IKH + 41°

   2(∠IKH) = 103 - 41

 m(∠IKH) = 31°

4). m∠AED = m∠AEB + m∠BEC + m∠CED

                  = 21° + 37° + 44°

                  = 102°

5). m∠JKG = 108°

    m∠JKG = m∠JKI + m∠IKH + m∠HKG

    108° = m∠JKI + 31° + 41°

    m∠JKI = 108° - 72°

    m∠JKI = 36°

6). m∠HKF = m∠GKF + m∠HKG

                  = m∠IKH + m∠HKG [Since, m∠GKF = m∠IKH]

                  = 31° + 41°

                  = 72°

7). m∠NQO = m∠MQN = 64°

8). m∠JKF = m∠JKI + m∠IKF

                 = 36° + 103°

                  = 139°

8). m∠MQO = 2(m∠NQO)

                    = 2(64)°

                    = 128°

9). m∠LQO = 156°

    m∠LQM = m∠LQO - m∠MQO

                    = 156° - 128°

                    = 28°

10. m∠NQP = m∠NQO + m∠OQP

                   = 64° + m∠LQM [Since ∠OQP ≅ ∠LQM]

                   = 64° + 28°

                   = 92°

Jessica went shopping and bought a pair of jeans that were on sale for 25% off the original price of $23.98. A 6% tax was also a
Ghella [55]

Answer:

$19.07

Step-by-step explanation:

First off we need to find the discounted price of the jeans that Jessica bought.

We find the discount by multiplying the original price by 25% or 0.25

Discount Price = 23.98 x 0.25

Discount Price = 5.99

Now we subtract the discount from the original price.

Discounted Price = 23.98 -5.99

Discounted Price = 17.99

Now that we have the discounted price, we then compute for the sales tax.

Sales Tax = 17.99 x 0.06

Sales Tax = 1.08

Then we add the sales tax to the discounted price.

Total Price = 17.99 + 1.08

Total Price = $19.07

Jessica spent $19.07 on the jeans.
