Answer:
4 4/7
Step-by-step explanation:
You multiply the n by 7 first because you are cross multiplying. So it would be 7n = 32.
So to simplify you would divide 32 by 7 to get n= 4 4/7
4 4/7 is a mixed number 4 is the whole and 4/7 is the fraction just to clarify
Or as a fraction it would be 32/7

Let the number of third-graders be x.
We have been given that the number of fourth-graders is 47.
Total number of students = 92.
Therefore, x + 47 = 92
x = 92 - 47
x = 45
Hence, there are 45 third-grade students.
The correct equation would be d=40h.
You can test this out by substituting the number of hours into h to find d.
Ex.
h=3 hours
d=40h
d=40(3)
d=120 (this matches up with the distance given in the table for 3 hours
Hope this helps!! :)
Answer:
6
Step-by-step explanation:
21-20 = 1
20-18 =2

15-11 = 4
We are subtracting 1 more each time
11-5 = 6
Answer:
i think probably 80°
Step-by-step explanation:
PQ = RS
2x+3 = 4x-3
x = 3
PTQ = RTS
9y-3x-1 = 5x+7y-5
2y-8x = -4
y-4x = -2
y-4(3) = -2
y-12 = -2
y = -2+12
y = 10
so PTQ = 9y-3x-1
9(10)-3(3)-1
90-9-1
80°

#8 - substitution property of equality
