x/7 has to be proportionate to 9.2/16.1 so find out how 7 relates to 16.1

16.1/7=2.3 and 7*2.3=16.1

then apply it to x and 9.2

9.2/2.3= 4 and 4*2.3=9.2

So, x=4

Please help me with this problem
Naya [18.7K]

Answer:

Dasha has 52 roses

Step-by-step explanation:

Rewrite the first sentence in an equation: (D= Dasha) (A= Anna)

D=4A

Rewrite the second sentence in an equation:

A+39=D

1) Substitute A+39 as D in the first equation:

A+39=4A

2) Subtract A from both sides:

3A=39

3) Divide both sides by 3:

A=13

4) Now substitute 13 as A in the second equation:

13+39=D

5) Solve:

D=52
