They are equivalent. They’re equivalent because 3+6=9 and 3(2+1) also equals 9 2+1 is 3 so you would have 3(3) and whatever number is in the parentheses you just multiply it with the other number and 3*3 is 9

Answer:
The cost of 1 videotape = $ 3.4
Step-by-step explanation:
Let us assume the cost of each cassette tap = $ m
So, the cost of each videotape = 2 x ( Cost of 1 cassette) = 2 x m = 2 m
Now, the cost of 3 cassette tap = 3 x ( Cost of 1 cassette) = 3 x m = 3 m
Also, the cost of 5 videotape = 5 x ( Cost of 5 videotape) = 5 x (2m) = 10 m
So, the cost of 3 cassette tap + 5 videotape = 3 m + 10 m
Also, given 3 blank cassette tapes and 5 blank videotapes costs $22.10 .
⇒ 3 m + 10 m = $22.10
or, 13 m = 22.10
⇒ m = 22.10/13 =1.7
or, m = $1.7
Hence, the cost of 1 cassette = m = $1.7
And, the cost of 1 videotape = 2 m = 2x ($1.7) = $ 3.4
Answer:
2 : 1
Step-by-step explanation:
Recipe :
Sugar = 2 cups
Flour = 3 cups
Butter = 1 cup
Chocolate chips = 1/2 cup
ratio of flour and butter to sugar?
Total cups of flour plus butter = (3 + 1) = 4 cups
Cups of sugar = 2 cups
ratio of flour and butter to sugar :
4 cups : 2 cups
= 2 : 1
I'm assuming that the first word is "four", with that said, this equation is quite simple. All you need to do to find the price per gallon is divide the cost of four gallons by four.
16.80 ÷ 4 = $4.20
