Miss Allen read for 3/4 of an hour less than the student who read the most. How long sis Miss Allen read for?

kolbaska11 [484]

Answer:

See Explanation

Step-by-step explanation:

Given

$Allen = \frac{3}{4}hr$ less than the most hour

Required

Hours read by Miss Allen

The question is incomplete, as the hours read by each student is not given.

To solve this, I will assume that the longest hours read by a student is x.

So, the expression for Miss Allen will be:

$Allen = x - \frac{3}{4}hr$

Assume that $x = 1hr$

The expression becomes

$Allen = 1hr - \frac{3}{4}hr$

Take LCM and solve

$Allen =\frac{4 - 3}{4}hr$

$Allen =\frac{1}{4}hr$

15-a=20 what value would make this true

sergejj [24]

Answer:

a = -5

Step-by-step explanation:

15 - a = 20

Move the constant of 15 to the other side by subtracting it.

-a = 5

Divide by -1 to make a positive.

a = -5

Check.

15 - (-5) = 20

15 + 5 = 20

20 = 20

Janelle is in charge of bringing in dry erase markers for everyone in her math group to use to work on a project. She brings 3 m

Papessa [141]

Let x represent the number of students in Janelle’s group. If Janelle brings 3 markers for each person in her group, then she brings 3x markers for x students. You also know that she brings 5 extra markers for everyone to share. Thus, the total amount of markers she brings is 3x+5.

If Janelle brings in 23 markers in all, then the equation 3x+5=23 represaents the mathematical model. 

3x=23-5,3x=18,x=6

Answer: there are 6 students in Janelle's group.
