Nickels = x
dimes = x + 4
quarters = x
Value of coins:
nickel = 5 cents
dime = 10 cents
quarter = 25 cents
5x + 10(x + 4) + 25x = 3.20
5x + 10x + 40 + 25x = 320
40x = 320 - 40
40x = 280
x = 280/40
x = 7
There are 7 quarters, 7 nickels and 11 dimes.
Answer:

Answer:
y = 4x -5
Step-by-step explanation:
Gradient is also known as slope . The gradient of a line is represented by the equation
Slope (m) = y - y1/ x - x1
Where m = 4 , x1= 1 and y1 = -1
Imputing the values into the equation
m = y - y1/ x - x1
4 = y - -1/x - 1
Cross multiply, we have
y + 1= 4(x - 1)
Expand
y+1= 4x - 4
Subtract 1 from both sides
y+1-1= 4x -4-1
y = 4x -5

Orlando's poster's length is 1 meter - 0.55 meter = 0.45 meter.
Amanda's " " " 0.85 meter
The difference in the lengths of their posters is (0.85 - 0.45) meter = 0.40 meter.
