Answer:

just keep in mind am not sure if the answer 6:15:20

Step-by-step explanation:

now we have ab= 2 : 5

               and bc= 3 : 4

so b is the common one between them so multiply both of the b together which will give u 15 so now we have b = 15

to get a multiply  2 by 3 to get 6 so a = 6

to get c multiply 4 by 5 to get 20 so c = 20

now I hope that its correct and that u understood

Which expression is equivalent to (3b 2r) (4b r)? 7b 2r 7b 3r 12b 2r 12b 3r.
Maslowich

To add the variables, add the coefficients with same variable. The expression which is equivalent to given expression is 7b+3r. The option 2 is the correct option.

<h3>What is equivalent expression?</h3>

Equivalent expression are the expression whose result is equal to the original expression, but the way of representation is different.

Given information-

The expression given in the problem is,

(3b+2r)+(4b+r)

Let the resultant expression of the above expression is x. thus,

x=(3b+2r)+(4b+r)

To add the algebraic terms open the brackets first,

x=3b+2r+4b+r

Separate the same variable terms,

x=3b+4b+2r+r

To add the variables, add the coefficients with same variable. Thus,

x=7b+3r

Hence, the expression which is equivalent to given expression is 7b+3r. The option 2 is the correct option.

Nick and Monica are paid $41.25 for their work. Nick worked 2.5 hours, and Monica worked 3 hours. They split the money according
vlada-n [284]

Answer:

BRIANLIEST PLZ

N = 18.75

M = 22.5

Step-by-step explanation:

Need the ratio of money paid to each. We know how the ratio of time is divided so we can use this ratio to find the amount paid.

T = t1 + t2 = 2.5 + 3 = 5.5

r1 =2.5/5.5

r2 = 3/5.5

Nick = r1 * 41.25 = 18.75

Monica = r2 * 41.25 = 22.5
