The answer is x equals the square root of y+1/4
Answer:
multiple choice have 30 questions
word problems have 8 questions
Step-by-step explanation:
x=multiple choice. y=word problems
2x+5y=100 ---eq1
x+y=38 ---eq2
y=38-x ---eq3
substitutet eq3 into eq1
2x+5(38-x)=100
2x+(-5x)+190=100
2x-5x=100-190
-3x=-90
x=-90/-3
x=30
substitute x to eq3
y=38-(30)
y=8
multiple choice have 30 questions
word problems have 8 questions
Answer:
factorise out a and x :
but from general factorization:
a » x
b » 2
therefore:
This is an example I put a dot where -2 3/4 should be
I believe the answer is 4
