How many solutions does this equation have? 6x+5=4x+5

Travka [436]

$:\implies \sf 6x +5 = 4x +5$

$: \implies \sf 6x +5 -4x = 5$

$:\implies \sf 2x = 5-5$

$:\implies \sf 2x = 0$

$:\implies \sf x = 0$

Seems like "6x+5=4x+5" has only one solution that's 0.

What is 33 percent of 400

Eduardwww [97]

<h2>QUESTION</h2>

What is 33% of 400?

<h2>ANSWER AND EXPLANATION</h2>

To find the percent of a number, you have to change the percent into a decimal or a fraction and multiply by the number.

<h3>DECIMAL</h3>

To change a percent into a decimal, remove the percent sign and move the decimal point 2 places to the left.

$33 \% \rightarrow 0.33$

Now that you have your decimal, multiply by 400:

$0.33 \times 400 = 132$

ANSWER = 132

<h3>FRACTION</h3>

To change a percent into a fraction, make the percent number as the numerator(top number) and 100 as the denominator(bottom number) since fractions are out of 100.

$33 \% \rightarrow \frac{33}{100}$

Now that you have your fraction, multiply by 400:

$\frac{33}{100} \times 400 = \frac{13200}{100} \rightarrow 132$

ANSWER = 132

Answer:

1.2 x 10⁴

Step-by-step explanation:

12,000 has 2 places of other numbers before a spam of zeroes.

Take the numbers before zeroes and put a decimal to the left of the last digit.

Last digit is 2 so a decimal goes before 2

1.2

Count how many places the decimal moved: this number is your power of 10.

12000. --> 1.2000

It moved 4 places.

12,000 = 1.2 x 10⁴
