Answer:

3.56*10^13

Step-by-step explanation:

8.9* 10^4  * 4*10^8

Multiply the number out front and then the exponents

8.9 * 4  * 10^4 * 10^8

When we multiply powers when the bases are the same, we add the exponents

35.6 * 10^(4+8)

35.6 *10^12

But this is not in proper scientific notation.  Only one digit before the decimal

Move the decimal one place to the left, that means we need to add 1 to the exponent

3.56 *10^(12+1)

3.56 * 10^13

The equation is 2.5x + 2y - 2 = 0.

<h2>Linear system</h2>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

He bought 2.5 pounds of apples that are x dollars a pound.

And 2 bags of lettuce for y dollars each.

The total cost is $2.

<h3>To find </h3>

The equation of this.

<h3>How to find the equation?</h3>

He bought 2.5 pounds of apples that are x dollars a pound.

Then the expression is 2.5x

And 2 bags of lettuce for y dollars each.

Then the expression is 2y

The total cost is $2.

Then the expression will be

    2.5x + 2y = 2

2.5x + 2y - 2 = 0

Thus the equation is 2.5x + 2y - 2 = 0.

More about the linear system link is given below.
