Answer:
3/8
Step-by-step explanation
Convert 3/4 to 6/8 to make it easier subract since this problem asks how much he has left.
So 6/8-3/8=3/8
1.9
Step-by-step explanation:
A = kB/C -----------(1)
A=12
B = 3
C= 2
substitute A, B and C into equation (1).
12 = K × 3/2
12 = 3k/2
12×2 = 3k
3K = 24
dividing bothsides by 3
3K/3 = 24/3
K = 8
substitute K = 8 into equation (1)
A = 8B /C --------------(2)
Equation (2) is the equation connecting
A,B and C.
Finding B when A = 10 and C = 1.5
10 = 8B / 1.5
10× 1.5 = 8B
15 = 8B
Dividing bothsides by 8 :
B = 15/8
B = 1.875
B = 1. 9 ( approximately)
0.6 pounds each
3+2=5
3/5 or 3÷5= 0.6
Melanie.
The possible ways of getting a 6 are (3,3), (2,4), (4,2), (1,5) and (5,1).
That is 5 ways.
The possible ways of getting a 7 are (1,6), (6,1), (5,2),( 2,5), (3, 4), (4,3).
That is 6 ways.
So Melanie made the better decision.
Given that in the weekly ad 5 pound bag of organic apples will cost 13.95 dollars
To find unit rate
Unit rate can be found in two ways either cost of 1 apple or no of apples for 1 dollars
I part:
5 apples = 13.95 dollars
1 apple = 13.95/5 (since direct variation)
Unit rate for one apple= 2.79 dollars
Part II:
13.95 dollars = 1 apple
1 dollar = 1/13.95 = 0.071
=0.07
But normally since apples are countable as 1,2 ... we use the first type of rate only unit rate per apple
10
2 1/2 ÷ 1/4 reduce
5/2 × 4/1 = 20/2
20 ÷ 2 = 10 pounds of flour per sugar
(I'm not very good at math so this might be wrong)
