The scale factor is 3/2
Step-by-step explanation:
Step-by-step explanation:
3y means 3 times y. It is normally used to shorten an equation with a variable to save room. The number is always placed before the variable.
The perimeter of a circle is equal to 2πR where R is the radius if we want the perimeter of the semicircle we divide by 2 and we get
P=πR=22π=22*3.14=69.08cm
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.
