Mumz [18]

Answer:

I'm glad you asked!

Step-by-step explanation:

So let's do it step by step.

Already she has to pay $5 for going in.

She has 2 whole pounds.

1.25 x 2=2.5 or 2 \frac{1}{2}

Add $5 and $ 2.5 .

5+2.5 = 7.5

Now let's do $1.25 divided by 10.

$$1.25 divided by $10 =0.125

Now let's do 0.125 times 4

0.125 x 4 = 0.5

Now let's add 7.5 to 0.5

7.5+0.5=8

Please Please Please help me with this answer

Alright, lets gets tarted.

Suppose there are x rows of tomato plants Krystyn make.

Again suppose there are n plants in each row.

We could find total plants by multiplying number of plants in each row with number of rows.

Hence total number of plants will be = x * n

But as per question, total number of plants are 54. It means

x * n = 54

Now, the number of plants in each row was 3 more than the number of rows means

n = x + 3

Putting this value of n in first equation we made

x * (x+3) = 54

x^{2} + 3x = 54

Subtracting 54 in both sides

x^{2} + 3x - 54 = 54 - 54

x^{2} + 3 x - 54 = 0

Factoring

(x-6)(x+9) = 0

Means x = 6 or x = -9

The number of rows can not be negaive.

Hence x = 6

It means number of rows of tomato plants will be 6. : Answer

Hope it will help :).
