Answer:
Step-by-step explanation:
Let x represent the total number of stdents that has all grades in the school.
There are three grades in the school. One grade has 1/3 of the students, this means that number of students that belongs tho this grade is 1/3 × x = x/3
One grade has 1/4 of the students, this means that number of students that belongs to this grade is 1/4 × x = x/4
Total number of students in both grades would be x/3 +/x/4 = 7x/12
The number of students in the remaining grade would be
x - 7x/12 = 5x/12
fraction of students in the remaining grade would be
(5x/12)/x = 5/12
The average rate of change = 1.59 ≈ 2
The average rate of change can be calculated by
1) The first one = 
= 1.5
2 ) the second can also be solved by ; 8 + 2/ 2 = 5
3 ) the third one will be 20 + 6 / 2 = 13
4) 8.5
5) 12.5
To calculate the average rate of change
we will first add all the distance
Adding all the distance we will get the sum = 3 + 8 + 20 + 10 + 10 = 51
The total time = 2 + 6 + 9 +15 = 32
Thus the average rate of change = 51 / 32 = 1.59

Answer:
4x+9=3q
Step-by-step explanation:
-3(2x-3)+10x=3q
-6x+9+10x=3q
4x+9=3q
Answer:
35
Step-by-step explanation:
Make equations, l = w+5 and 2l + 2w = 150
Substitute w+5 into 2l + 2w = 150
Simplify to get 4w + 10 = 150
Subtract 10 from both sides to get 4w = 140
Divide both sides by 4 and you get 35 as width
Answer:
544 cm²
Step-by-step explanation:
hello,
to find the tsa of a rectangular prism, you use:
tsa = 2 ( lw + lh + wh )
in this case, l = 16 cm, w = 6 cm and h = 8 cm.
knowing these informations, you can proceed with using the formula.
tsa = 2 [ ( 16*6) + ( 16*8 ) + ( 6*8) ]
= 2 [ 96 + 128 + 48 ]
= 2 ( 272 )
= 544 cm²
please try to understand how i worked this out, and do let me know if you have any questions.
have a great day! thank you!
