Answer:

The solution to the set of linear equations is:

(5,-4)

Step-by-step explanation:

Hey there!

In order to solve this system of equations, we can put the equations equal to each other since both equations are equal to y

6-2x=-4x+16

Now we simplify

2x=10 ---> x=5

So now that we know that x is equal to 5, we can find the value of y

let's substitute it in one of the equations

y=6-2(5) ---> y=-4

So now we know that the point where the two equations intersect is:

(5,-4)

This is going to be our solution

The cost of a jacket increased from $90.00 to $103.50. What is the percentage increase of the cost of the jacket?
a_sh-v [17]

Answer:

So the Percentage Increase = 15 %    

Step-by-step explanation:

Given:

Original price = $ 90.00

New Price = $103.50

To Find:

Percentage Increase = ?

Solution:

Percentage Increase =\frac{Difference in Value* 100}{Original value}%

Now In our Given Data

Difference in Value = New Value - Original Price

Putting in the values

Difference in Value = 103.50 - 90.00

                                 = $13.50

Now we Know all the value and the formula is

Percentage Increase =\frac{Difference in Value* 100}{Original value}%

Putting in the values

Percentage Increase =\frac{13.50* 100}{90.00}%

                                   =\frac{1350}{90.00}%    

                                           = 15%

which tells us that

 Percentage Increase = 15 %

Please help me i gotta get this finished... :P
Llana [10]

Answer:

A) it depends. If they bought 10 calculators, we would multiply 31.25 by 10. 31.25x10=$312.50

B)Divide 500 by 31.25. Since each calculator is $31.25, we divide $500 by it to see how many they can buy with $500. 500/31.25=16
