Answer:

n = 7

Step-by-step explanation:

5n + 12 = 9n - 16 (Given)

5n + 12 - 12 = 9n - 16 - 12 (Subtraction Property of Equality)

5n = 9n - 28 (Simplify)

5n - 9n = 9n - 9n - 28 (Subtraction Property of Equality)

-4n = -28 (Simplify)

$\frac{-4n}{-4} = \frac{-28}{-4}$ (Division Property of Equality)

n = 7 (Simplify)

In his will, Mr. Banks left 50% of the value of his property to his

Rashid [163]

The value of Mr Banks's property was $250,000

What percentage of the property is left for charity?

The percentage of property left for charity can be determined as the 100% of the property minus all percentages given to others

% left for charity=100%-50%-22%-16%

% left for charity=12.00%

12.00% of the property=$30,000

1.00% of the property =$30,000/12

1.00% of the property =$2,500

100.00% of the property=$2500*100

100.00% of the property=$250,000

A salesperson earns $320 per week plus 8% of her weekly sales. The expression representing her earnings is 320 + 0.08x. Which of

Arturiano [62]

Answer:

Here, x represents the weekly sale

As per the statement:

A salesperson earns $320 per week plus 8% of her weekly sales.

"8% of her weekly sales" means $\frac{8}{100}x = 0.08x$

then;

the expression which represents her earning = $320+0.08x$

"At least" means $"\geq"$

then;

the sales necessary for the salesperson to earn at least $1000 in the one week

⇒ $320+0.08x\geq 1000$

Subtract 320 from both sides we have;

$0.08x\geq 680$

Divide both sides by 0.08 we get:

$x\geq 8500$

Therefore, the sales necessary for the salesperson to earn at least $1000 in the one week is: greater than or equal to $8500 i.e $x\geq 8500$
