4x - 2y =7<br> X +2y =3 <br> What is x and y ??
NARA [144]

Answer:

x=2. y=1/2

Step-by-step explanation:

4x-2y=7. Equation 1

x+2y=3. Equation 2

Add the two equations

(4x+x) +(-2y+2y) =7+3

5x+0=10

5x=10 divide both sides by 5

X=2

Substitute x=2 in equation 2

2+2y=3

2y=3-2

2y=1. Divide both side by 2

Y=1/2

If the scale on a map is 1/4 in. = 50 miles, how many miles do 3 3/8 inches represent?
Korvikt [17]
Hey there Fish Girl!

So, if \left[\begin{array}{ccc}1/4 \end{array}\right] equals 50 miles, then we would do this multiplied by . . . . 

So, if we would want to go to 3 whole, we would then have to go to the number 3 of course. So then, we do \left[\begin{array}{ccc}4*3=12\end{array}\right] and then from this, we would have to multiply this my 50.

The reason to why we would have to do this is because 1/4 of a mile is 50, so then, sense we are trying to get to the number 3, then, from doing this,we would determine a figure out how many miles this would conclude to be.

\left[\begin{array}{ccc}12*50\end{array}\right]   =\left[\begin{array}{ccc}\boxed{\boxed{600}} \ so \ far!\end{array}\right]

So, now, we have covered 3 as a whole, then we would have to see how 3/8 and also 1/4 can relate to each other.

So, in this case,\boxed{\boxed{ \frac{3}{8} \ would \ be \ almost \ \boxed{half} \\ \ because \ it \ is \ almost  \frac{4}{8} }}

So, most likely, it would stay the same as it is, 1/4 because this is almost half to.

SO ALL WE WOULD NEED TO DO NOW IS TO ADD . . . . . 

\left[\begin{array}{ccc}\left[\begin{array}{ccc}\boxed{\boxed{600+50 \ or  \frac{1}{4}=650}} \end{array}\right]\end{array}\right]

YOUR CORRECT AND FINAL ANSWER TO THIS QUESTION WOULD BE. . . . 

\left[\begin{array}{ccc}650 \ miles\end{array}\right]

Hope this helps you fish Girl! :)

Kerry and three friends went out for dinner. They split a large pizza and each person had a salad and a soda. They want to leave
klio [65]

Answer:

Each person will pay $ 7.20

Step-by-step explanation:

First we find the total bill

Pizza $18.60

Salad $2.50

<u>Soda $2.25</u>

Total  $ 23.35

Sales Tax would be=  8 1/4% of $ 23.35 =$ 1.926= $ 1.93

Tip = 15% of $ 23.35= $ 3.5025

Total Bill paid= $ 23.35 + $ 1.93+ $3.50= $ 28.7825 or $ 28.78

Now dividing the bill among 4 persons = $ 28.78/4= $ 7.196 or $ 7.20

Paying the bill equally is better  and convenient than paying alone as each person gets an equal share of pizza, salad and the soda.
