Answer:
3
Step-by-step explanation:
Answer:
There were 40 2-point questions and 9 3-point questions.
Step-by-step explanation:
To solve this situation, write two equations. One for the number of questions and one for the number of points.
Let x be the number of 2 point questions.
Let y be the number of 5 point questions.
x + y = 49
Now since x are each worth 2 points, the total points is 2x.
And since y are each worth 5 points, the total points is 5y.
So 2x + 5y = 125. Substitute one of the equations into the other to solve for the variables.
x + y = 49 becomes x = 49 - y. Substitute it.
2(49-y) + 5y = 125
98 - 2y + 5y = 125
98 + 3y = 125
3y = 27
y = 9
Substitute y = 9 back into the equation x = 49 - y to find x.
x = 49 - 9
x = 40
Answer:
Im pretty sure ita square root 0.4
Step-by-step explanation:
if you square root it, its the only one that doesnt repeat and doesnt stop, which makes it irrational.
The x-intercept is 4/3 and y-intercept is -4/5
Step-by-step explanation:
Given equation of line is:
To find the x-intercept, we put y=0 in the equation
Dividing both sides by -3
To find the y intercept, we put x=0
Dividing both sides by -5
Hence,
The x-intercept is 4/3 and y-intercept is -4/5
