Answer:

First step is "Solve the parenthesis". It means subtract 1.5x from 4x.

Step-by-step explanation:

The given equation is

$5(4x-1.5x)+12=4x-2$

We need to find the first step o solve this equation.

Step 1: Solve the parenthesis.

$5(2.5x)+12=4x-2$

Step 2: Multiply.

$12.5x+12=4x-2$

Step 3: Isolate variable terms on left side.

$12.5x-4x=-12-2$

$8.5x=-14$

Step 4. Divide both sides by 8.5.

$x=\dfrac{-14}{8.5}$

$x\approx -1.647$

Therefore, the firs step is "Solve the parenthesis".

If he puts 300 sunfish into the pond, he will put 225 perch in the pond.

<h3>What is a ratio?</h3>

A ratio is the comparison of one thing to another. Generally, ratios compares value.

They store the children pond keeping a ratio of 4 sunfish to 3 perch. Therefore, the ratio of sunfish to perch will be as follows

4:3

If he 300 sunfish into the pond , the number of perch that will be in the pond can be calculated as follows:

4 / 3 = 300 / x

cross multiply

4x = 900

x = 900 / 4

x = 225

Answer:

18.75 bows

Step-by-step explanation:

This talented group of dogs has 25 yards of ribbon. They want to cut the ribbon to make bows and awards. If each piece of ribbon needs to be 3/4 of a yard, how many bows will they be able to make?

The total number of yards =25 yards

Each piece of ribbon = 3/4 of a yard

Hence, the number of bows they can make is:

3/4 × 25 yards

= 18.75 bows.

What is the ultimate goal when solving equations? What do you want your final answer to look like?

STALIN [3.7K]

Answer:

$\huge\boxed{\text{To get x on one side of the equation:} \ \ x = ...}$

Step-by-step explanation:

When we solve for an equation, our goal is to find the value of the variable. Any variable can be used, but for the time being let’s assume we use $x$ .

We can algebraeically solve equations until we get the value of x - in which we will have x equal to something.

Say we have the equation $5x+5=20$ . Our goal is to find the value of $x$ . <u>We can do this by getting x isolated on one side so we have something equal to x</u>.

We can subtract 5 from both sides and divide both sides by 5.

$5x=15\\\\x=3$

We now know the value of $x$ since it’s on one side of the equation.

Hope this helped!
