Answer:
P = 2L + 2W
35 cm = 2(5 cm) + 2(W cm)
W = 12.5 cm
Step-by-step explanation:
P = 2L + 2W
35 cm = 2(5 cm) + 2(W cm)
35 cm - 10 cm = 2W cm
2W cm = 25 cm
w cm = 12.5 cm
Answer:
Step-by-step explanation:
Given that the equation x + y = z relates the whole numbers x, y, and z.
This implies x,y,z all three are whole numbers
Hence we get x+y =z
x = z-y
where y is a whole number
So y can be 0,1,2.....
From this we can say x can take at most the value z in case y =0 other wise x has to be less than z
So comparison of x,y,z would give
( the equality applying only when y =0)
Answer:
n + q = 20
5n + 25q = 300 or 0.05n + 0.25q = 3
Step-by-step explanation:
You know that you have some nickels and some quarters, and together there are 20 coins. So if n represents the number of nickels, and q represents the number of quarters, you can use this equation:
n + q = 20
You also know that together the coins total three dollars. We know that a nickel is worth 5 cents and a quarter is worth 25. So if n and q still represent the number of each type of coin, we can use this equation:
5n + 25q = 300
or
0.05n + 0.25q = 3
The reason I said 300 in the first equation is because you are counting the number of cents. There are 300 cents in 3 dollars.
