(MARKING BRAINLIEST) For Alexandra's lemonade recipe, 8 lemons are required to make 4 cups of lemonade.
Amiraneli [1.4K]

Answer:

2 1

8 4

10 5

Step-by-step explanation:

We already know that it takes 8 lemons to make 4 cups of lemonade. So, to get the number of lemons needed to make 1 cup of lemonade, we divide the lemons and cups by 4.

8 divided by 4 = 2 and  4 divided by 4 = 1. Therefore, it takes 2 lemons to make 1 cup of lemonade.

By this logic, to figure how many cups are needed for 10 lemons, and since we know 2 lemons = 1 cup of lemonade, we multiply the lemons and cups by 5. 2 times 5 is 10 (lemons) and 1 times 5 is 5 (cups). Therefore, 10 lemons are needed to make 5 cups of lemonade.

To plot this on the coordinate axes, the first point goes (2,1) second being (8,4) and third point being (10,5).

side note - is this delta math? I feel your pain

Tom, Mary and Bill are aged 10,12 and 15 years respectively. They share 259 euros in the same ratio as their ages. Find how much
tigry1 [53]

Answer:

70 , 84 , 105

Step-by-step explanation:

sum their ages , 10 + 12 + 15 = 37

divide the amount by this sum to find the value of one part of the ratio.

259 ÷ 37 = 7 ← value of 1 part of the ratio , then

10 parts = 10 × 7 = 70 euros ← Tom's share

12 parts = 12 × 7 = 84 euros ← Mary's share

15 parts = 15 × 7 = 105 euros ← Bill's share
