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:
If I am not mistaking is 6
Step-by-step explanation:
Answer number 1
Ich would das that the derivative of
f(x) = 6x+2
is 6
because of derivative 6x it is 6 and the derivative of 2 is 0
Answer:
Step-by-step explanation:
-8-4v=40 add 8 to both sides
-4v=32 divide both sides by -4
v= -8
3v+2v=25
5v=25 divide both sides by 5
v=5
x/2 - 8 = -14 add 8 to both sides
x/2= - 6
-6 * 2= -12
check
-12/2-8=-14
-6-8=-14
-14= -14
-6+n/3= -3 add 6 to both sides
n/3=3
3*3=9
check
-6+9= -3
-3 = -3
