Answer:
I would use it you don't those very often and I'm speaking that out of human answer.
To solve for a number x,
3x+4x-2=15
7x-2=15
7x=17
x=2 3/7
or x=~2.43
was one of your answer choices either of the first two equations?
Answer:
20 + 1 + 0.9 + 0.07
Step-by-step explanation:
Given the number 21.97 ;
To wite in expanded form:
Tens ___ Unit ____ tenth ____ hundredth
2_______ 1 _______ 9_________ 7
2 = 20
1 = 1
9 = 0.9
7 = 0.07
Hence,
20 + 1 + 0.9 + 0.07
Think of how many there are. im not sure if you put these into ratios or not...
like for number 3 think of how many numbers 1-9 are multiples of three
1 2 3 4 5 6 7 8 9
and once you get that number you make it out of 9 because there were 9 numbers
Example
3:9 3/9
for questions one and two its out of 52 and if you don't know how many clubs and hearts are in a deck you can look it up and put it in a ratio with 52
