solong [7]2 years ago

Step-by-step explanation:

We are given with the inequality |2x + 1| ≤ 5 and asked to solve the equation. In this case, we take first the positive side, that is 2x + 1 ≤ 5. this is equal to 2x ≤ 4 or x ≤ 2. For the negative side, the equality is -5 ≤ 2x + 1. This is equal to -6 ≤ 2x or -3 ≤ x. Hence the solution is  -3 ≤ x ≤ 2. The answer is B. closed dots on -3 and 2 with shading in between. The equal in ≤  means closed dots.

Which sequence shows the numbers in order from least to greatest? A. -2/3 , 1/5 , -3/4 B. 1/5 , -2/3 , -3/4 C. -3/4 , -2/3 , 1/5
Rom4ik [11]

Answer:

C. -3/4, -2/3, 1/5

Step-by-step explanation:

Just from observation, you can tell the 1/5 will be the greatest because all the other fractions are negative. Then, I converted them to decimal form to make it easier.

-2/3 = -0.6666666 (the 6 goes on forever)

-3/4 = -0.75

1/5= 0.20

Then, you put them in order.

-3/4 would be the least .

Followed by, -2/3

Finally, 1/5

DeAngelo is training for a half marathon. Today he is running 13.25 miles. He jogs for the first half hour at a rate of 5.5 mile
Nezavi [6.7K]
For this case, the first thing we must do is define a variable.
 We have then:
 p: rate in miles per hour for the last 1.5 hours
 We now write the equation that models the problem.
 We have then:
 (0.5) * (5.5) + 1.5p = 13.25

 Rewriting we have:
 2.75 + 1.5p = 13.25

 From here, we clear the value of p.
 We have then:
 1.5p = 13.25 - 2.75

p = 10.5 / 1.5

p = 7
 Answer:
 
DeAngelo's rate for the last 1.5 hours of his run is 7 miles per hour.

If an exercise routine requires 24 crunches for every 16 squats, how many squats would need to be done for every 78 crunches? Gr
Angelina_Jolie [31]

Answer:

The correct answer is 52 squats.

Step-by-step explanation:

An exercise routine requires 24 crunches for every 16 squats.

Therefore the routine would require 1 crunch for every \frac{16}{24} squats.

And by the use of unitary method, the routine would require 78 crunches for every \frac{16}{24} × 78 squats = 52 squats.

Thus for every 78 crunches attempted, the exercise routine would requires 52 squats to be done.
