Answer:

$x$

Step-by-step explanation:

<u><em>The correct question is</em></u>

Solve. −3/5x+1/5>7/20 Drag and drop a number or symbol into each box to show the solution

we have

$-\frac{3}{5}x+\frac{1}{5} >\frac{7}{20}$

Solve for x

Multiply by 20 both sides

$-12x+4 >7$

subtract 4 both sides

$-12x >7-4$

$-12x >3$

divide by -12 both sides

Remember that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

$x$

simplify

$x$

Answer:

Step-by-step explanation:

We are asked to perform the subtraction

x² + xy - 3y² - (5x² - xy + y²) ← distribute the parenthesis by - 1

= x² + xy - 3y² - 5x² + xy - y² ← collect like terms

= (x² - 5x²) + (xy + xy) + (- 3y² - y² )

= - 4x² + 2xy - 4y²

In 2010, the population of Kingsford was 8000. By 2014 the population had increased by 15% and 2/5 of the population was age 12

<h2>Hello!</h2>

The answer is: The population age 12 or under was 3680.

If in 2010 the population of Kignsford was 8000, and by 2014 the population had increased by 15% we need to calculate the total population and then, calculate how many people was age 12 or under.

We must remember that we cannot work with percentage values, so, to make 15% a real number, we need to divide it by 100:

$15(Percentage)=\frac{15}{100}=0.15$
