Answer: x=-3 and y= -15

Step-by-step explanation: 1 Substitute y=5xy=5x into 4x-2y=184x−2y=18.

-6x=18

−6x=18

2 Solve for xx in -6x=18−6x=18.

x=-3

x=−3

3 Substitute x=-3x=−3 into y=5xy=5x.

y=-15

y=−15

4 Therefore,

\begin{aligned}&x=-3\\&y=-15\end{aligned}

​

 

x=−3

y=−15

How do you solve what is 30% of $240
DerKrebs [107]
The Answer would be x=72. Why? Because \frac{x}{240} =  \frac{30}{100}.   Fraction  \frac{30}{100} is your %.  You Cross multiply 240 * 30 = 100x
240 time 30 = 7200. you want x to  be alone so you do 7200 divided by 100 equaling 72. So you get x=72.

Jackson purchased a pack of game cards that was on sale for 22% off. The sales tax in his county is 6%. Let y represent the orig
Ymorist [56]

Answer:

Final cost = 0.9328y

Step-by-step explanation:

Assume,

Original price = y

Given:

Discount = 22%

Sales tax = 6%

Computation:

Sales tax will be added on sale value

So,

Sales price = y[100%-22%]

Sales price = 0.88y

Price after sales tax :

Final cost = 0.88y[100% + 6%]

Final cost = 0.88y[106%]

Final cost = 0.9328y

Suppose Wesley is a marine biologist who is interested in the relationship between the age and the size of male Dungeness crabs.
Eva8 [605]

Answer:

20.24 cm

Step-by-step explanation:

Here, since the age of the crab is given in months and the regression line was computed using the age in months, we just have to replace the value of the age in the formula to estimate the size.

The formula obtained for the estimated size Y was

Y = 9.1411 + 0.4775X  

where X is the age in months

Replacing X with 23.2417, we get

Y = 9.1411 + 0.4775*23.2417 = 20.24 cm
