Bill is 6 years older than Mary. The sum of their ages is 48. What are the equations used to find their ages?

Answers

Step-by-step explanation:

Mary's age = x

Billi's age = x+6

So, Mary age + Billi age = x + (x + 6)

Sum of their ages = 2x + 6

So, 2x + 6= 48

2x = 48 - 6

2x = 42

x = 42/2

Mary age = x = 21

And Billi age = x +6= 21 + 6 = 27

So Mary = 21

And Billi = 27

Lets check!

21 + 27 = 48

So therefore their ages add up to 48

So the answer is correct!

Bob gets paid an annual salary of $30,000 and earns 5% commission on all sales he makes. If Bob wants to make $6,000 this month, how much in sales does he need to have?
a.
$50,000
b.
$70,000
c.
$90,000
d.
$120,000

Answers

Answer:

The answer is 70,000 sales.

Bob gets paid an annual salary of $30,000, which means that monthly he gets:

$30,000 : 12 months = $2,500 per month

x - number of sales

Bob earns 5% commission on all sales he makes: x * 5% = x * 0.05 = 0.05x

The function is:

f(x) = 2,500 + 0.05x

Bob wants to make $6,000 this month: f(x) = 6,000

2500 + 0.05x = 6000

0.05x = 6000 - 2500

0.05x = 3500

x = 3500 : 0.05

x = 70000 sales

Step-by-step explanation:

Sales for the month should amount to $70,000

Annual salary = $30,000

Commission on sales = 5%

To make 6000 in a month :

Monthly salary = $30000 / 12 = $2500

Month earning = $2500 + 5% × (monthly sales)

Month earning = $6000

Let month sales = m

6000 = 2500 + 0.05m

6000 - 2500 = 0.05m

3500 = 0.05m

m = 3500 / 0.05

m = 70,000

Sales for the month should be 70,000

What is surface area?

The surface area of any shape is the area of the shape that is faced or the surface area is the amount of area covering the exterior of a 3D shape.

Here,
The area of the picture is given as,
= 2x × x
= 2x²

The area of the whole painting with frame.

= (x + 1)(2x+ 3)
= 2x² + 5x + 3

The area of the frame is given as,
= area of picture with frame - an area of the picture,
= 2x² + 5x + 3 - 2x²
= 5x + 3

Thus, the required area of the frame shown is 5x + 3. Option C is correct.

Answers

Answer:

8,10,12

Step-by-step explanation:

Answer:

integer 1 = 8

integer 2 = x+2 = 8+2 = 10

integer 3 = x+4 = 8+4 = 12

Step-by-step explanation:

integer 1 = x , smallest

integer 2 = y , x+12

integer 3 = z , largest, x+4

three times the smallest is twice the largest.

3 (x) = 2 (x+4)

solve for x:

3x = 2x + 8

3x-2x = 8

x = 8

Replacing:

integer 1 = 8

integer 2 = x+2 = 8+2 = 10

integer 3 = x+4 = 8+4 = 12
