Answer:

x = 4y - 1/120y, y ≠ 0

Step-by-step explanation:

First, let's subtract 2x from both sides of the equation:

2x + 5 ⋅ 3y ⋅ 8x - 2 - 2x = 2x + 4y - 3 - 2x

Simplify:

5 ⋅ 3y ⋅ 8x - 2 = 4y - 3

Multiply the 5 ⋅ 3 ⋅ 8:

120xy - 2 = 4x - 3

Add 2 to both sides of the equation:

120xy - 2 + 2 = 4x -3 + 2

Simplify:

120xy = 4y - 1

Divide both sides by the 120y:

120xy/120y = 4y/120y = 1/120y; y ≠ 0

So,

x = 4y - 1/120y, y ≠ 0

I hope this helps!

<h3>What is a BODMAS rule?</h3>

For the Bracket, Order, Division, Multiplication, Addition, and Subtraction rules, BODMAS stands for Bracket, Order, Division, Multiplication, Addition, and Subtraction.

Given expression ;

9(5x + 1) ÷ 3y

Follow the BODMAS rule;

Step 1; Divide

$\rm \frac{9(5x+1)}{3y} \\\\ \frac{3(5x+1)}{y} \\\\$

Step 2; Multiply

$\rm \frac{9(5x+1)}{3y} \\\\ \frac{(15x+3)}{y} \\\\$

Hence the expression obtained after solving the given expression is, $\rm \frac{(15x+3)}{y}$

SSSSS [86.1K]

Answer:

Teresa drive <u>90 miles</u> on Tuesday.

Step-by-step explanation:

Given:

Teresa drove on Monday, Tuesday and Wednesday.

On monday her driving distance was 120 miles.

The ratio of Wednesdays distance is 3/5.

The ratio of Wednesdays distance to Tuesday's distance is 5/4.

Now, to find the miles Teresa drive on Tuesday:

Teresa driving distance on Monday was = 120 miles.

Her driving distance on Wednesday is = $\frac{3}{5}\ of\ 120.$

$=\frac{3}{5} \times 120\\\\=0.6\times 120\\\\=72\ miles.$

Now, her driving distance on Tuesday is:

$\frac{5}{4} \ of\ 72\\\\=\frac{5}{4} \times 72\\\\=1.25\times 72\\\\=90\ miles.$

Therefore, Teresa drive 90 miles on Tuesday.
