Answer: 12 bracelets
Step-by-step explanation:
I am assuming you meant to write “Brianna has four pink bracelets, 1/3 of all her bracelets are pink. How many bracelets does Brianna have?”
If that’s what you mean to write proceed on my writing.
Write out what you know
4 pink bracelets= 1/3 of her bracelets
Equation:
4+4+4=12 bracelets
1/3+1/3+1/3=3/3=100% of her collection
Answer:
Domain and range are the set of all real numbers.
Step-by-step explanation:
Given that Ann thought of a number N, multiplied it by 5 and added 7. Then she told the result R to Jim
Here no restriction is mentioned for the number N.
It can be any number but real.
Hence we can say that domain is the set of all real numbers
For range let us calculate y for any x
If Ann thought of x as the number then
she would multiply by 5 to get 5x and add 7 to get 5x+7
Hence y =5x+7
Since y has no exception here range can also be the set of all real numbers
Answer: 3x+6 = 2(x+6)
Step-by-step explanation:
Ralph's age: y; Sara's age: x
Ralph is 3 times as old as Sara: y = 3x
In 6 years, Ralph will be only twice as old as Sara will be then: (y+6) = 2(x+6)
Substitute y=3x into (y+6) = 2(x+6).
3x+6 = 2(x+6)
Yes, 11.25 per song is a unit rate because it is for each song.
