Answer:
I'm not fully sure but id say the principle value would be choice C
Step-by-step explanation:
Set equal to each other since both equal 90
5x-6y=-10x-6y
add 6y to both sides
5x=-10x
x=0
5(0)-6y=-90
-6y=90
divide by -6
y=-15
(x,y)
(0,-15)
Answer:
25 students.
Step-by-step explanation:
A line plot is a simple graph that shows relationship among the values in a data using a number line.
From the line plot, each dot represents a student. While the number on the line shows the number of blocks walk each day by each student.
It can be deduced from the line plot that;
Only 1 student walks through 7 blocks, 2 walk through 5 blocks, 8 walk 4 blocks, 5 walk 3 blocks, 5 walk 2 blocks and 4 walk through 1 block to school each day.
So that;
1 + 2 + 8 + 5 + 5 + 4 = 25
Therefore, the number of students who took part in the survey is 25.
Divide 35423 by 15 and round the answer down to a whole number, then you get 2361. If you subtract 15*2361 from 35423 you get the remainder 8. So answer C is correct.
