Answers

Answer:

-32

Step-by-step explanation:

if we multiply - 2 and -6 it becomes positive so it will be 12.

-2 multiply 22 will be -44

12 - 44 is -32.

answer : -32

you distribute so you do -2 times -6 which is 12. then -2 times 22 which is -44.

you end up with 12 - 44, which equals -32.

3 plus four times a number.

Answers

Answer:

3 + 4x

Step-by-step explanation:

Let "a number" be x.

Therefore "four times a number" is 4 multiplied by x which is 4x.

Now add 3 for "3 plus".

3 + 4x

Answer:

Our equation would be: 3 + 4x.

Let's say x=8

That would now make our equation:

3 + 4(8) =

Step-by-step explanation:

But let's solve this equation :)

First, we would add 3+4, to get 7.

Then, we would multiply the 7 by 8.

Lastly, we know 7 x 8 = 56

So, 3+4(8)= 56

But we could also create a function statement out of this.

Our statement for this equation would be:

When x equals 8 the answer or in algebraic terms the "output" is 56.

,  Hope this helps :)

5. Gardener Gary planted 21 rows of tomatoes
and squash. He planted twice as many rows of
tomatoes as rows of squash. How many tomato
plants were planted if there are 12 plants per
row?

Answers

Answer:

168

Step-by-step explanation:

first find out how many rows of squash there are

21 = x + 2x

21 = 3x

7 = x

then find out how many rows of tomatoes there are

7 × 2 = 14

if there are 12 plants per row, we can multiply

14 × 12 = 168

Gardener Gary planted 168 tomato plants

How to determine the number of yellow leaves?

Let the rows of tomato be x and the rows of squash be y.

So, we have:

x + y = 21

The statement twice as many rows of tomatoes as rows of squash means that:

x = 2y

Substitute x = 2y in x + y = 21

2y + y = 21

This gives

3y = 21

Divide by 3

y = 7

Substitute y = 7 in x = 2y

x = 2 * 7

x = 14

This means that Gary planted 14 rows of tomato.

The number of tomato plants is then calculated using

Tomato plants= 14 * plants per row

This gives

Tomato plants = 14 * 12

Evaluate the product

Tomato plants = 168

Hence, Gardener Gary planted 168 tomato plants
