Answer:
D. (90, 60)
Step-by-step explanation:
A proportional relationship is a relationship in which the ratios of two variables are equivalent.
If we take two points on the graph such as (45, 30) and (30, 20), we can see that they can both be simplified to the ratio 3:2. Using this we can find the correct answer. From looking at all the points we can see that only (90,60) would also form a ratio of 3:2, thus d would be the correct answer.
Answer:
41
Step-by-step explanation:
5(4) - 7(-3)
20 + 21 (because it's a negative times a negative and that equals a positive)
41
5×20%=100% so 1360mg is 80% of the daily requirement. The total requirement is 1360/0.8=13600/8=1700 mg.
In algebra, symbols are used to represent numbers. Example: 5x=20 or 4x=24
