Answer: Sup. it's 16
Step-by-step explanation: Hope dis helps
if x = 2 and our equation is 10 +3(12 ÷ 3x), then u use substitution
So, the equation would become 10 + 3(12 ÷ 3(2)), which is 10 + 3(12 ÷ 6)
12÷6= 2, so the equation becomes 10 + 3(2).
3(2) = 6, so the equation would be 10 + 6 = 16
The common denominator is 40.
Answer:
She catered for 40 people.
Step-by-step explanation:
According to the information given, you can write an equation that indicates that 30 people multiply for its cost that is $10 plus the number of people after 30 for its cost that is $9 is equal to $390. According to this, the equation is:
10(30)+9x= 390, where
x= number of people after 30
Then, you can solve for x:
300+9x= 390
9x=390-300
9x= 90
x=90/9
x=10
The answer is that she catered for 40 people, 30 people at a cost of $10 and 10 people for a cost of $9.
Well, I believe one ordered pair that is a solution to the equation would be P(3,1). Since by plugging in the X and y values into the equation the left hand side is equal to the right hand side.
Y = X + 2/5
1 = 3+2/5
1 = 5/5
1 = 1.
