Peggy had three times as many quarters as nickels. She had $1.60 in all. How many nickels and how many quarters did she have?. .
Andru [333]

Let

n-------> the number of nickels

q------> the number of quarters

we know that

1\ quarter=\$0.25\\1\ nickel=\$0.05

so

0.05n+0.25q=1.60 ----> equation A

q=3n ----> equation B

substitute equation B in equation A

0.05n+0.25[3n]=1.60

0.05n+0.75n=1.60

0.80n=1.60

n=2

Find the value of q

q=3*2=6

therefore

<u>The answer part a) is</u>

the number of nickels are  2  and the number of quarters are 6

<u>the answer Part b) is</u>

The expressions that represents the number of quarters is

q=3n

What is the slope intercept form of -11x+2y=1?
ikadub [295]

Answer:

y=  11/2 x+1/2

Step-by-step explanation:

Slope Intercept form: y = mx + b where m = slope of the line, b = y intercept and (x,y) are coordinate points on the line.

To put this in slope-intercept form, you need to solve the equation for y

-11x + 2y  =  1

<u>+11x             +11x</u>  add 11x to both sides of the equation

      <u>+2y</u> = <u>1 + 11x</u>

        2         2     Divide both sides by 2 (so y is by itself)

y = 11/2x + 1/2

Polygon ABCD is plotted on a coordinate plane.If the polygon translates 3 units to the left and 1 unit down,the length of diagon
Hatshy [7]
The length of the diagonal will be 2.

When a translation is performed on a shaped, it simply moves location. The size and shape of the object do not change. Therefore, the length of AC will remain the same at all times.
