Lilit [14]

Answer:

20% increase

Step-by-step explanation:

Initial price: $2.25

New price: $2.70

Percentage=(new price - initial price)×100/(initial price)

p=(2.70-2.25)×100/2.25=45/2.25=20%

Need help please due tommorw

Kisachek [45]

Answer:

Solution (4,3)

Step-by-step explanation:

2x-7y= -13

2x-7y= -13

-8x +7y= -11

$\frac{-bx}{-6} =\frac{-24}{-6}$

x= 4

__________

2x-7y= -13

2(4)-7y=-13

8-7y= -13

subtract 8 from both sides

$\frac{-7y}{-7} =\frac{-21}{-7}$

divide by -7

y= 3

hope it helps..

have a great day!!

Answer:

I would use the sale price.

Step-by-step explanation:

20% of 150 is 30. So, you get $30 off if you use the sale price rather then the $15 coupon.

ABc bookstore sells magazines according to the demand function p= -Q + 42, where p is the price and q is the quantity. if the bo

LekaFEV [45]

Answer: $Q=37$ (37 megazines)

Step-by-step explanation:

1. To solve this problem you only need to solve for the quantity Q and substitute the values of p, as following:

- Solve for Q:

$p=-Q+42$

$Q=42-p$

- If the bookstore charges $5 for a magazine, you need to substitute $p=5$ into the formula, as following:

$Q=42-5\\Q=37$

2. Therefore, the answer is 37 megazines.

Step-by-step explanation:

Let us explain the meaning of coincidental system of equations

If an equation of a line is ax + by = c, and we multiply or divide all the terms by the same number n, then we will have another equation nax + nby = nc, which represents the same line as the first equation
The two equations ax + by = c and nax + nby = nc form a coincidental system of two linear equations
This system has many solutions (all the points on the line)

∵ 2x + 3y = -17 is one equation in a coincidental system of two

linear equations

- To find the other equation multiply each term by n

∴ The second equation is 2nx + 3ny = -17n

∵ The other equation is _y = _x - 102

∵ The other equation is 2nx + 3ny = -17n

- Compare them to equate the like terms

- Subtract both sides by 2nx to have the same form of the other

equation

∴ 3ny = -2nx - 17n

- Equate the numerical terms

∴ -17n = -102

- Divide both sides by -17

∴ n = 6

- Substitute the value of n in the other equation

∴ 3(6)y = -2(6)x - 17(6)

∴ 18y = -12x - 102

∴ The other equation is 18y = -12x - 102

The missing numbers are 18 and -12
