what values make t true is my inequality is (5-2t)<-4
Answer:
t ≥ 5
Step-by-step explanation:
I) Find what t needs to be at least, represent this with u:
5 - 2u = -4
-2u + 5 = -4 (Simplify by swapping signs and terms for 5 - 2u)
-2u = -9 (Subtract 5 from both sides)
2u = 9 (Make both sides positive values)
u = 4.5 (Divide both sides by 2)
II) Make an inequality for t:
Since t needs to be equal to or greater than 4.5, our inequality will be:
t ≥ 4.5

Answer:
The rate of speed is 5 miles per hour
0: 20 + 5
1: 25 + 5
2: 30 + 5
3: 35 + 5
4: 40
Step-by-step explanation:
Answer:
The rate of speed is 5 miles per hour.
Step-by-step explanation:
Choose two lines of data as two ordered pairs:
(0, 20) and (4, 40)
The rate of speed is the same as the slope of the line that passes through those two points.
slope = (difference in y)/(difference in x)
slope = (40 - 20)/(4 - 0) = 20/4 = 5
The slope is 5, so the speed is 5 mph
Answer: The rate of speed is 5 miles per hour.

The length of a rectangle is 1 more than twice its width. The rectangle has an area of 210 m2.
Let w represent the width of the rectangle. What expression represents the length?
Enter your answer in the box.
Answer:
length = 2w + 1
Step-by-step explanation:
width = w
length = 2w + 1
area: 2w^2 + w = 210
w = 10.
Width = 10m
length = 21m
6 pipes are required to fill a tank in 80 minutes. If we use 5 such types of pipes, how much time it will take to fill the tank?
Answer:
96 minutes
Step-by-step explanation:

Answer:
66 min and 7 seconds
Step-by-step explanation: 80 divided by 6 and then multiply the answer by 5

Answer:
100%
Step-by-step explanation:
It says 38 out of 38 votes were for hunger relief. If it were like that, it would be 100%. Same as if it were 22 out of 22 votes. Like, think about if you were taking a test with 20 questions, and you got 20 questions right. You'd get a hundred percent, right? Same thing here, just a different equation.
Hope this helps
Answer:
Like the person who said 100% its correct.

Renee bought 7 potatoes at the supermarket. The shortest diameter of each, in centimeters, is shown below
Answer:
2, 3, 4
Step-by-step explanation:
Renee bought 7 potatoes at the supermarket. The shortest diameter of each,
in centimeters, is shown below.
2, 3, 4, 4, 6, 6, 7
After Renee used one potato to make dinner, the median diameter of the remaining potatoes was 5 centimeters. Which of these could be the diameter, in centimeters, of the potato Reneetsed?
Solution:
The median of a group of numbers is the middle number when the group of numbers are arranged in a sorted manner, either ascending or descending.
The median of an even group of numbers, is gotten by taken the average of the two innermost numbers.
Given that the diameter of the potato as:
2, 3, 4, 4, 6, 6, 7
Given that after removing one potato, the median of the remaining potatoes was 5 centimeters.
After removing one potato, the remaining would just be 6. 6 is an even number, hence the median would be the average of the 2 middle numbers.
To get 5 cm, it has to be the average between 4 and 6. This is only possible when a potato of diameter 2,3 or 4 is removed.
If potato with diameter 2 is removed, the remaining is 3, 4, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5
If potato with diameter 3 is removed, the remaining is 2, 4, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5
If potato with diameter 4 is removed, the remaining is 2, 3, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5
