1. When simplifying you need to isolate the variable x, the first step would be to subtract 8 from both sides.

2. Subtract the parts from the total:

179 - 44 = 135

Now divide the remaining amount by the hourly rate:

135 / 45 = 3 hours.

The first equation would be the correct one: 179=44+45x

A footbridge is 5 feet wide and is built with wood planks that are 6 inches wide. How many planks wide is the path?

Ede4ka [16]

Here we have to know the conversion between feet and inches.

1 Feet = 12 inches (This is given and is to be known)

So the 5 feet wide footbridge when converted to inches would be about 5*12 = 60 inches

The width of the footbridge in inches = 60 inches

Each wooden plank is 6 inches,

So the number of wooden planks that are required to build the foot bridge of 60 inches = 60/6 = 10 planks

Hence, the path path is 10 planks wide

in a farm there are 600 mango trees. the number of trees in each row is 10 less than twice the number of rows. does each row hav

iren [92.7K]

The area of the farm is the number of trees on it.

Each row of the farm does not have 50 trees

Let

$x \to$ number of rows

$y \to$ number of trees in each row

So, we have:

$y = 2x - 10$ --- twice less than the number of rows

The area of the farm is:

$Area = x \times y$

Where

$Area = 600$ --- the number of trees

So, we have:

$x \times y = 600$

Substitute $y = 2x - 10$

$x \times (2x - 10) = 600$

Substitute 50 for x

$50 \times (2 \times 50 - 10) = 600$

$50 \times (100 - 10) = 600$

$50 \times 90 = 600$

$4500 = 600$

The above equation is not true.

This means that, each row does not have 50 trees
