Answer: No, Cammie is not correct. She can mow in one hour (See explanation).
Step-by-step explanation:
Convert the mixed number to an impoper fraction:
1. Multiply the whole number part by the denominator of the fraction and add the product to the numerator.
2. The denominator does not change.
Then:
Let be "x" the acres Cammie can mow in one hour.
You know that she can mow in 25 minutes, then you can set up the following proportion (Remember that 1 hour has 60 minutes):
Solving for "x", you get:
Convert from improper fraction to mixed number:
1. When you divide 6 by 5, the quotient is 1. This will be the whole number part.
2. The remainder is 1. This will be the numerator.
3. The denominator does not change.
Then:
Therefore, she can mow in one hour.
Answer:
1st, 2nd and 6th options
Step-by-step explanation:
Given
- x +
= 6x ( multiply through by 6 to clear the fractions )
4 - 6x + 1 = 36x ← option 1 will have the same solution set
----------------------------------------------------------------------
Adding the 2 fractions on the left side gives
+
- x = 6x , that is
- x = 6x ← option 2 will have the same solution set
------------------------------------------------------------------------
From
4 - 6x + 1 = 36x ( add 6x to both sides )
5 = 42x ← option 6 will have the same solution set
