It's the first one.

If you work backwords, I'd say it's easier. 3y swuared is 9y2, and 11 squared is 121. Then just keep the sign the same

We can use the equation:

3.25 is the cups of flour used for every cup of sugar.

Where 'f' represents flour and 's' represents sugar.

A florist sells a bouquet of roses

NikAS [45]

Answer:

Bouquets of roses = 20

Bouquets of carnations = 08

Step-by-step explanation:

Let,

x be the bouquets of roses sold

y be the bouquets of carnations sold

According to given statement;

x + y = 28 Eqn 1

16x + 10y = 400 Eqn 2

Multiplying Eqn 1 by 16

16(x+y=28)

16x + 16y = 448 Eqn 3

Subtracting Eqn 2 from Eqn 3

(16x+16y)-(16x+10y) = 448 - 400

16x + 16y - 16x - 10y = 48

6y = 48

Dividing both sides by 6

$\frac{6y}{6}=\frac{48}{6}\\y=8$

Putting y=8 in Eqn 1

x + 8 = 28

x = 28 - 8

x= 20

Hence,

Bouquets of roses = 20

Bouquets of carnations = 08
