Answer:
10cm represents $10
2cm represents $2
10cm also represents 1week
For every week Andre checks 10cm, deduct 2cm which represents $2 donation for food bank, and remaining 8cm represents $8 left for his Dad's gift.
in 5weeks, which is 50cm, save $8 per week/ per 8cm = $8 × 5 = $40
in 5weeks, which is 50cm, he donate $2 per week/ per 2cm = $2 × 5= $10
So this is a solution problem the answer is 3/4 cups or 75% milk and 1/4 cups or 25% cream, here's why:
m = milk
c = cream
m + c = 1
This is because when you add milk and cream then you get one cup of solution
.02m + .18c = .06
When you add together the percentages the goal is to have .06 or 6%
100m + 100c = 100
2m + 18c = 6
I do this to make it easier to solve
200m + 200c = 200
-200m - 1800c = -600
The "m's" cancel out
-1600c = -400
c = 1/4 or .25 or 25%
Now we add c back in
m + 1/4 = 1
Solve for m
m = 3/4
Thus: 3/4 milk and 1/4 cream
Two pairs of decimals that add up to 14.1 would be 8.4 and 5.7
Answer:
1/3 ≅ .33333
Step-by-step explanation:
If 'i' is 1, then 5+i is 6. 2 over 6 is 1 over 3. (2/6 = 1/3) 1 over 3 is also .3333... forever repeating.
Hope this helps!
I would multiply 4/7 by 5 and 3/5 by 7 to get 20/35 and 21/35. The Least Common factor is 35
