If you have for example
19.90$ you round it as 20
if u have 19.05 you have it as 19 only because its not near to the next number to it
Answer:
The required expression is f = 3+6t
Step-by-step explanation:
Let t represent number of tens
Let f represent number of fives
So, the expression for number of fives can be formed by using:
The number of fives is 3 more than six times the number of tens.
f = 3+6t
So, the required expression is f = 3+6t
Well, first, you need to add up the amount of ten fridges and ten pianos. than you see if its heavier or lighter... > or <....... do you remember how to graph?
Answer:
A. n = -13/4
Step-by-step explanation:
well, it can be changes to
-10/4 = 3/4 + n
subtract 3/4
-13/4 = n
The invese switches x and y so basically
if
f(21)=z then f⁻¹(z)=21
therefor
f(z)=21 and f⁻¹(21)=z
basically solve for the value that makes the functino equal 21
21=6(x+2)-3
add 3 both sides
24=6(x+2)
divide by 6
4=x+2
minus 2
2=x
answer is 2
