She has 6 on Wednesday
Since we know that she has 4/9 left, 4/9 of 27 is 12. So she has 12 on Tuesday. Now 2/4 or 1/2 is left on Wednesday. Half of 12 is 6. So she has 6 left
Answer:
B
Step-by-step explanation:
1. In order to determine the inequality, you must first solve the solution set to determine what x is less than.
So you would do this:
1 + 2x < 9 Subtract 1
2x < 8 Divide by 2
x < 4
2. Next, you need to understand the difference between an open circle and a closed circle shown on the solution sets.
An open circle is equal to the following inequalities:
<, >
A Closed circle represents inequalities in situations such as:
greater than or equal to, or less than or equal to
3. Because the inequality above represents only less than or greater than the inequality sets should have an open circle being used.
Since x is less than 4 it should be moving to the left of the line inequality set.
Answer:
the total distance walked is 20 km
Step-by-step explanation:
The computation of the total distance he walked is shown below:
Let us assume the total distance walked be d
Now the total time would be
Total time = (d ÷ 2) ÷ 8 + (d ÷ 2) ÷ 5 = 3.25
d ÷ 16 + d ÷ 10 = 3.25
(5d + 8d) ÷ 80=3.25
13d = 260
d = 20 km
Hence, the total distance walked is 20 km
