If a 12 oz bottle of shampoo lasted for 16 weeks, we have a ratio of 12:16 which can be shortened to 3:4.
Now if we have 18 oz bottle we know that it's 1/2 more than 12 oz bottle, so the ratio will be also 1/2 more. So if it was 12:16, the new ratio will be:
12 + (1/2 * 12) : 16 + (1/2 * 16)
12 + 6 : 16 + 8
18 : 24
It means that 18 oz bottle should last for 24 weeks. Of course the ratio has to stay the same in its lowest form in both situations and as 18:24 can be shortened to 3:4, it proves it's correct :)
≠ means not equal to
L x w = 36
2L + 2w = 30
1. Find the multiples of 36
1 and 36
2 and 18
3 and 12
4 and 9
6 and 6
2. Figure out which set of numbers multiplied by 2 equals 30.
For 1 and 36:
2(1) + 2(36) = 2 + 72 = 74 ≠ 30
For 2 and 18:
2(2) + 2(18) = 4 + 32 = 36 <span>≠ 30
For 3 and 12:
2(3) + 2(12) = 6 + 24 = 30
So your answer is 3 and 12</span>
Answer:
x = 12
Step-by-step explanation:
24 = 3x - 12 (opposite sides of a parallelogram are equal)
24 + 12 = 3x
36 = 3x
36/3 = x
12 = x
Answer:
x = -4
Step-by-step explanation:
Divide both sides by -2.
x= - 8/2
Simplify - 8/2 to -4.
