Raise 49<span> to the </span>power<span> of </span>2<span> to get </span><span>2401.
</span><span><span>7^3</span>x+4=2401x+1

</span>Raise 7<span> to the </span>power<span> of </span>3<span> to get </span><span>343.
</span><span>343x+4=2401x+1

</span>Since <span>2401x</span><span> contains the </span>variable<span> to solve for, move it to the left-hand side of the </span>equation<span> by subtracting </span><span>2401x</span><span> from both sides.
</span><span>343x+4−2401x=1

</span>Add <span>343x</span><span> and </span><span>−2401x</span><span> to get </span><span><span>−2058x</span>.
</span><span>−2058x+4=1

</span>Since 4<span> does not contain the </span>variable<span> to solve for, move it to the right-hand side of the </span>equation<span> by subtracting </span>4<span> from both sides.

The large rectangle shown here is 3cm by 5 cm. What is a direct way to determine the area of the rectangle in square centimeters
dlinn [17]

Answer:

Place the squares on the rectangle.

Step-by-step explanation:

Hello!

The area of the 1cm by 1cm square is 1 square cm.

We can solve for the area by placing multiple of those squares in the larger rectangle.

If we place it, we get 15 placed squares, with a total area of 15 square cm. This relies on the meaning of area, as we are simply measuring the number of square cm taken up by the object.

We would place 3 rows of 5 squares, representing a height of 3 cm (side length of 3 squares), and a length of 5 cm (side length go 4 squares).

This also proves the area formula A = L * W, as we multiple the side lengths to find the number of square units.

If a certain brand of icecream is 99% fat free, how many cups would you have to eat to ingest the same amount of fat that would
sdas [7]

Answer:

<em>10,000 cups </em>

Step-by-step explanation:

Direct proportional quantities are such that their quotients are always the same number. Example: If I need one cup of sugar to prepare 5 candies, I will need 2 cups of sugar to prepare 10 candies. The quotient 5/1 is equal to the quotient 10/2

Let's suppose a cup of regular ice cream would have 100 parts of fat.

The brand of ice cream mentioned in the question is 99% fat-free which means for every cup of their ice cream, we'll only get 1 part of fat. The relation is 100/1.

If we wanted 100 parts of fat out of fat-free ice cream we would need 100*100/1=10,000 cups of it

These numbers won't change if we used another number instead of 100 in the example shown.
