Brianna house for pink bracelets 1/3 of all her bracelets are pink how many bracelets does rihanna have

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

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
