There are five students wearing glasses. There are three more boys than girls wearing glasses. On your worksheet, solve the ques
Llana [10]

Answer:

Four boys and one girl.

Step-by-step explanation:

Total students wearing glasses = 5

Separate the students by x and x + 3. It is x + 3 for the boys because there are three more boys wearing glasses.

Girls = x

Boys = x + 3

Total = 5

<u>Calculate:</u>

x + x + 3 =5

2x + 3 =5

2x = 2

x = 1

Boys wearing glasses = (1) + 3 = 4

Girls wearing glasses = 1

Please Please Please help me with this answer
nignag [31]

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 :).

2x^2+2x is it simplified
Tpy6a [65]

Answer:

Yes it is simplified

Step-by-step explanation:

2x^2 is not a like term to 2x because 2x does not have an exponent. Therefore, you cannot add 2x to 2x^2. So it is as simplified as it can be at this point
