A dozen is 12. 12 times 12 is 144
Assuming the question is "at what rate did the chemist heat the solution," the answer is the chemist heated the solution at +4.5 degrees Celsius per minute.
75-21=54
54/12=4.5
Answer:
x < 3
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
4*x-7-(5)<0
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
4x - 12 = 4 • (x - 3)
Equation at the end of step 1 :
Step 2 :
2.1 Divide both sides by 4
Solve Basic Inequality :
2.2 Add 3 to both sides
x < 3
Ok since the athlete an equal distance of 2 days a week and he runs a total of 11 miles in 5 days you will need to think back so before he had 11 miles done next weak he had a total of 19 miles so you will start at 11 then count up to 19.
Use a number line to show how many days it took for the athlete to get 19 miles.
Then once you do the number line count the lumps and that’s how many days it took for the athlete to get 19 miles.
Hope this helped.
