It’s solving systems of equations

Answers

Answer:

7 quarters, 8 nickels

Step-by-step explanation:

So the system of equations you have is:

x + y = 15

0.25x + 0.05y = 2.15

Here's how to solve:

first, multiply both sides of the equation 0.25x + 0.05y = 2.15 by 100 to get rid of the decimal places:

25x + 5y = 215

Then, you can divide both sides by 5 to simplify it more:

5x + y = 43

Now, you have the system of equations:

5x + y = 43

x + y = 15

Now subtract the two equations:

4x = 28

divide both sides by 4

x = 7

plug x = 7 into the equation x + y = 15 to solve for y:

7 + y = 15

subtract 7 from both sides

y = 8

So you know that there are 7 quarters and 8 nickels.

Hey store buys a jacket for $20 then sells it to customers for 80% more than what is the selling price of the jacket

Answers

Given:

Cost of a jacket = $20

Then sells it to customers for 80% more than.

To find:

The selling price of the jacket

Solution:

We have,

Cost of a jacket = $20

Selling price = cost + 80% of cost

= [tex]20+\dfrac{80}{100}\times 20[/tex]

= [tex]20+\dfrac{8}{1}\times 2[/tex]

= [tex]20+16[/tex]

= [tex]36[/tex]

Therefore, the selling price of the jacket is $20.

Write an exponential function in the form y=ab^x that goes through points (0, 18)and (3, 6174)

Answers

Answer:

[tex]y = 18 \times {7}^{x} [/tex]

Step-by-step explanation:

Using the formula for exponential function,

[tex]y = ab {}^{x} [/tex]

Let plug in 0,18.

[tex]18 = ab {}^{0} [/tex]

Using the zero power rule,

[tex]b {}^{0} = 1[/tex]

[tex]18 = a \times 1[/tex]

[tex]a = 18[/tex]

Since a equal 18 let plug in what we know so far

[tex]y = {18b}^{x} [/tex]

Now let find b.

Let use the other point, 3,6174

[tex]6174 = {18b}^{3} [/tex]

Divide 18 by both sides and we get

[tex]343 = b {}^{3} [/tex]

Take the 3rd root of 343

[tex] \sqrt[3]{343} = b = 7[/tex]

b=7

The equation is

[tex]y = 18 \times 7 {}^{x} [/tex]

what 2 numbers multiply to -63 and add to-2

Answers

7*-9
=-63 and 7+-9 adds to -2

Two numbers are 7 and -9, so their product is -63 and sum is -2.

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Let two numbers are x and y

Given,

The multiplication of 2 numbers is -63

[tex]x\times y =-63[/tex]

The addition of 2 numbers is -2

[tex]x+y =-2[/tex]

[tex]x=-2-y[/tex]

On substituting x in [tex]x\times y =-63[/tex]

[tex](-2-y)y=-63[/tex]

[tex]-2y-y^2=-63[/tex]

[tex]y^{2} +2y-63=0[/tex]

[tex](y-7)(y+9)=0[/tex]

[tex]y=7\\y=-9[/tex]

[tex]x=-2-y\\[/tex]

At y=7

x=-9

At x=-9

y=7

Thus, two numbers are 7 and -9

Two friends, Emma and Alice, are growing out their hair. They plan to cut it off at a certain point and donate it to a charity that makes wigs for people with cancer. Emma's hair is already 10 centimeters long and grows at a constant rate of 2 centimeters per month. Alice's hair is 30 centimeters and growing at a speed of 1 centimeter per month. If the girls get their hair cut on a certain day, they will have exactly the same length to donate. How long will their hair be?

Answers

Answer:

50 cm

Step-by-step explanation:

Let

x = number of months

Emma = 10 + 2x

Alice = 30 + x

Equate the equation of both girls

10 + 2x = 30 + x

10 - 30 = x - 2x

-20 = - x

x = 20

How long will their hair be?

Emma = 10 + 2x

= 10 + 2(20)

= 10 + 40

= 50cm

Alice = 30 + x

= 30 + 20

= 50 cm
