Answer:
This is proportional since rearranging it would get x/y = 2, which is an example of direct proportionality.
Step-by-step explanation:
Answer: $56
Step-by-step explanation:
Each day he feed them 4 fish food containers. How many days is a week 7. So 7x4 is 28. All we have left over is $2.00
so we just multiply 28x2. That sums up to $56!
For 1 cookie, cup of flour needed = 5
so, for 144, it would be: 144 * 5 = 720
Then, final answer is 720
Let me know, if you have some doubt
Answer:
i) 9
ii) 19 pens, 7 pencils, 3 erasers
Step-by-step explanation:
i) 171 = 3² x 19
63 = 3² x 7
27 = 3³
Highest Common Factor/HCF (171, 63, 27) = 3² = 9
Largest no. of bags = 9
ii) In each bag,
No. of pens = 171 / 9 = 19
No. of pencils = 63 / 9 = 7
No. of erasers = 27 / 9 = 3
To solve a compound inequality, first separate it into two inequalities. Determine whether the answer should be a union of sets ("or") or an intersection of sets ("and"). Then, solve both inequalities and graph. To find the solution of the compound inequality, we look at the graphs of each inequality and then find the numbers that belong to both graphs—where the graphs overlap. For the compound inequality x>−3 and x≤2, we graph each inequality. if you use this formula you will be able to get the answer
