Step-by-step explanation:
Answer:
25 4-point questions and 75 2-point questions
Step-by-step explanation:
Let x = no. of 4-point questions
Then 3x = no. of 2-point questions
So, x + 3x = 100
4x = 100
x = 25 = no. of 4-point questions
and 3x = 3(25) = 75 = no. of 2-point questions
-5*-2=-10
The factors to multiply to give negative 10 is -5 and 2
6 plus negative two gives you negative four. The factors to add to give you -4 is 6 and -2
Answer:
<h2>12</h2>
Step-by-step explanation:
So our equation is:
(7x+5)+(5x+3)+(12x-20) = 276
First remove parenthesis:
7x+5+5x+3+12x-20=276
Combine like terms:
24x-12 = 276
Add 12 on both sides:
24x = 288
Divide:
288/24 = 12
