In the first equation graph will touch x axis because equation have x intercept but in the 2nd equation graph will not touch the x axis. BECAUSE it doesn't have x intercept.
Answer: 155 fifth grader students.
Step-by-step explanation:
Given that 80% = 124 fifth grader students, the difference between 80% and total number of fifth grader students is 100% - 80%, which is 20%.
Therefore, if 80/100 = 124
(100/100- 80/100) = x
We cross multiply:
0.8x = 0.2 x 124
0.8x = 24.8
Divide both sides by 0.8
x = 24.8/0.8
x = 31
Total number of fifth grader students is 124 + 31 = 155
Answer:
n+3 = 15 ; n = 12
3n -6 = 12; n=6
Step-by-step explanation:
more than means it comes after
a number
n
3 more than
n+3
is 15
n+3 = 15
Subtract 3 from each side
n+3-3 = 15-3
n = 12
Subtract from comes after
three times a number
3n
six subtracted from
3n -6
is 12 means equal to
3n -6 = 12
To solve add 6 to each side
3n -6+6 =12+6
3n = 18
Divide by 3
3n/3 =18/3
n =6
