Answer:
0.012t + 28 = 30
Step-by-step explanation:
The depth starts at 28 meters. The amount of increase in t minutes will be 0.012t, so the total depth after t minutes is ...
0.012t +28
We want to find when that is equal to 30, so the appropriate equation is ...
0.012t +28 = 30
A number can replaced with a variable like x
(X+3)4=16
4x+12=16
4x=4
X=1
(X/4)+3=24
X/4=21
X=84
Answer:
49 third graders
Step-by-step explanation:
From the question:
The music teacher receives 9 boxes of recorders and there are six recorders in each box
The total number of recorders the teacher received =
1 box = 6 recorders
9 boxes = x
Cross Multiply
x = 9 × 6 recorders
x = 54 recorders.
She hands them out to third graders and has 5recorders left .
How many third graders received a recorder?
The amount of recorders shared =
54 recorders - 5 recorders
= 49 recorders
If 1 recorders was given to a third grader,
Therefore, the amount of third graders that received a recorder is 49 third graders
