Answer:
300 students
Step-by-step explanation:
If 195 students is 65%, then we can divide 195 by 65 to find what 1% is.
195/65= 3
So 1% of the 8th grade class is 3 students. We want to know how many students are in the whole class, which would be 100% of the class.
If we multiply the 3 (which is 1%) by 100 (to get 100%) we can find the total number of students.
3x100=300
We can check this by finding 65% of 300, and seeing if that is 195.
300x.65=195
It does check out.
Answer:
infinite number of solutions
Step-by-step explanation:
6(x + 7) = 6x + 42 ← distribute parenthesis on left side
6x + 42 = 6x + 42
Since the expressions on both sides are the same then any value of x will be a solution, that is
The equation has an infinite number of solutions
