Answer:

Step-by-step explanation:

You have 90 nickels

Since 20 nickels = 1 dollar you have 4 dollars and 10 nickels left over

The ten nickels left = 1/2 a dollar or 50 C

You have 16 dimes

10 dimes = 1 dollar

You have 1 dollar and 6 dimes left over.

So you have 1 dollar and 60 C

You have 16 quarters.

4 Quarters = 1 dollar

16/4 = 4 dollars. No quarters are left over.

You have 7 fifty-cent pieces

2 fifty cent pieces = 1 dollar

7/2 = 3 dollars and 50 cents left over.

I don't exactly know what you want as a final answer, but here is what I think it is

nickels =                     4 dollars and 50 cents

dimes   =                     1 dollar and   60 cents

quarters                      4 dollars

fifty cent pieces          3 dollars        50 cents

Adjustments                 1                     60 cents*

Totals                           13                    60 cents.

*The adjustment comes from 2 values of 50 cents each and 60 cents which cannot be combined with anything.

Answer:

$13.60

Step By Step:

A nickle is worth 5 cents.

A dime is worth 10 cents.

A quarter is worth 25 cents.

5 Cents • 90 Nickles = 450

10 Cents • 16 Dimes = 160

25 Cents • 16 Quarters = 400

50 Cents • 7 fifty-cent pieces = 350

450 + 160 + 400 + 350 = 1360

A dollar is worth 100 cents.

1360 ÷ 100 = $13.60

Took Gage 1 of a gallon of paint to create a mural of his favorite team the Grizzlies. He was asked to replicate his mural for 8
Charra [1.4K]

Answer: He will need 8 gallons of paint for the other murals.

Step-by-step explanation:

Given: 1 gallon of paint was required to create 1 mural.

Since replicates have the same dimensions, i.e same total surface area.

So, if 8 replication need to be made, the quantity of the paint required for this will be

8  x (Quantity required for 1 mural)

= 8 x 1

= 8 gallons

Hence, he will need 8 gallons of paint for the other murals.

PLEASE HELP
valina [46]

Answer:

Step-by-step explanation:

You have 3 unknowns: a, b, and c.  It's our job to find them algebraically.  I'm going to start with the point where x = 0 and y = 7.  You'll see why in a minute.  Filling in the standard form of a quadratic

y=ax^2+bx+c  using (0, 7):

7=a(0)^2+b(0)+c  gives you that c = 7.  We will use that value now when we write the next 2 equations.  Now the point (-2, 19):

19=a(-2)^2+b(-2)+7  and

19=4a-2b+7 so

12 = 4a - 2b

Now for the next point (-1, 12):

12=a(-1)^2+b(-1)+7  and

12=a-b+7  so

5 = a - b

Now we have a system of equations (the 2 bold font equations) that we will solve by elimination:

 12  =  4a  -  2b

  5  =   a   -    b

Multiply the bottom equation by -4 to get a new system:

 12  =  4a  -  2b

-20  = -4a  +  4b

Add those together to get rid of the a terms and end up with

-8 = 2b so

b = -4

Now we can sub in -4 for b to solve for a.  I'm using the second bold type equation to do this:

5 = a - (-4) and

5 = a + 4 so

a = 1 and the equation for the quadratic function is

y=x^2-4x+7

2x-10/4=3x<br> −10<br> −1<br> 2<br> 11
evablogger [386]

Answer:

<h2>-1</h2>

Step-by-step explanation:

\dfrac{2x-10}{4}=3x\qquad\text{multiply both sides by 4}\\\\2x-10=12x\qquad\text{subtract}\ 2x\ \text{from both sides}\\\\-10=10x\qquad\text{divide both sides by 10}\\\\-1=x\to x=-1
