Ok, think of 16.4 as 16.40 and 16.5 as 16.50
so between 40 and 50 there are lots of numbers
pick any three
Ex: 16.42, 16.49, 16.45
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.
Answer:
I think x is 1/2.
Step-by-step explanation:
Because the triangles are similar, you can set 9x + 1 = x + 5. Subtract x and 1 from both sides to get 8x = 4. divide and you get x = 1/2.
(double check me though.)
