Answer:
40 - 2 point questions and 4 - 5 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 = 44
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 = 100. Substitute one of the equations into the other to solve for the variables.
x + y = 44 becomes x = 44 - y. Substitute it.
2(44-y) + 5y = 100
88 - 2y + 5y = 100
88 + 3y = 100
3y = 12
y = 4
Substitute y = 4 back into the equation x = 44 - y to find x.
x = 44 - 4
x = 40
Answer:
2
Step-by-step explanation:
Obtain the greatest common factor of both 12 and 10
Factors of 10 = 1, 2, 5, 10
Factors of 12 = 1, 2, 3, 4, 6, 12
From the above, the greatest common factor of 10 and 12 is 2
Hence, smallest number of pencils using the boxes is 2
Answer:
B
Step-by-step explanation:
It’s B
ABD=CBD=1/2 ABC
Let, the water capcity of tank = x
it would be x*3/4 = 42
x = 42*4 / 3 = 168/3 = 56
So, the tank can hold up to 56 gallons
