4x + 8 = 12x

7x - 11 = -4x

x = 19/3

Hope this helped☺☺

Hi there!

To solve this problem, we need to simplify:

4x + 8 = 7x - 11

First, we subtract 4x from both sides of the equation:

8 = 7x - 11

Now, we add 11 to both sides of the equation to get rid of the -11:

19 = 7x

Now, we divide both sides of the equation by 7 to isolate x:

19 / 7 = x

x = 2 5/7

Hope this helps!

Fiona planted tomato plants in her back yard earlier this year. So far, they have produced 55 tomatoes. From past experience, sh
Harrizon [31]

if we deffine the first week as w₁ = 55, the recursive relation that tells us the number of tomatoes on week n will be:

wₙ = 55 + (n - 1)*14

<h3>How to find the recursive formula?</h3>

We know that, at the moment, the tomato plants produced 55 tomatoes, so that is our first element.

We also know that the tomato plants give 14 tomatoes each week, so in week 2 the number of tomatoes is:

w₂ = 55 + 14

On week 3:

w₃ = 55 + 14 + 14

And so on, so if we deffine the first week as w₁ = 55, the recursive relation that tells us the number of tomatoes on week n will be:

wₙ = 55 + (n - 1)*14

A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 150 nails an
forsale [732]

The system 150x+400y=1950 and x = y+2 could be used to determine the number of small boxes and large boxes ordered where x represents the number of small boxes and y represent the number of large boxes.

Step-by-step explanation:

Given,

Number of nails in small box = 150 nails

Number of nails in large box = 400 nails

Total nails in ordered boxes = 1950 nails

Let,

x be the number of small boxes ordered.

y be the number of large boxes ordered.

According to given statement;

150x+400y=1950          Eqn 1

The contractor bought 2 more small boxes than large boxes

x = y+2                           Eqn 2

The system 150x+400y=1950 and x = y+2 could be used to determine the number of small boxes and large boxes ordered where x represents the number of small boxes and y represent the number of large boxes.
