Answer:
The answer is 1 2/3. (One and two thirds)
Step-by-step explanation:
-20 / -12
The negative signs will cross out.
Each number is able to divide by 4.
20 divided by 4 is 5.
12 divided by 4 is 3.
5/3 = 1 2/3
Mile, Inch, Foot. We Americans do not use the metric system.
Let
x = loaves of bread
y = batches of muffins
You must make a system of two equations with two unknowns that describe the problem
3.5x + 2.5y = 17 --- (1)
0.75x + 0.75y = 4.5 --- (2)
Resolving we have
x = 6-y (from (2))
replacing in (1)
3.5 (6-y) + 2.5y = 17
21 - 3.5y + 2.5y = 17
y = 21-17 = 4
Then substituting in (2)
x = 6-y = 6-4 = 2
Answer
