Answer:

1a) t = 0.17b

1b) $36.03

2) 51,167.50

Step-by-step explanation:

1a) 17% converted to a decimal (divide by 100) = 0.17. Multiply that by the amount of the bill (before tipping) to get the amount of the tip

1b) The bill of $248 represents the entire bill (100%) plus the tip amount (17%) which makes 117%. As a decimal, this is 1.17.

To find what the cost was without the tip, divide the bill total by 1.17

248/1.17 = 211.97. That was the bill before the tip was added.

248-211.97 = 36.03 was the tip added.

2) 5.5% converted to a decimal is 0.055

0.55 x 48,500 = 2667.50

$2,667.50 + $48,500 = 51,167.50

Or, you can use what we did in 1b, and his new salary is 1.055 times 48,500

1.055 x 48,500 = 51,167.50

A polynomial is factored using algebra tiles

dezoksy [38]

Answer:

A) $x^2-2x-8$

Step-by-step explanation:

The polynomial factored is equal to the area of the algebra tiles. This means the quadratic is

$x^2 + x+ x -x -x -x -x-1-1-1-1-1-1-1-1\\x^2-2x-8$

After writing out each tile as a term, combine like terms to simplify. This ia the quadratic.

$x^2-2x-8$

How many solutions does this linear have y= 5x-1 -15x-3y=3?

musickatia [10]

-15x - 3y = 3

-15x - 3(5x-1) = 3 [input y]
-15x - 15x - 3 = 3 [distribute 3 over 5x and -1]
-30x - 3 = 3 [combine like terms]
-30x = 6 [add 3 to eliminate the negative]
x = $\frac{6}{-30}$ [divide by -30 to get x alone]
x = $\frac{1}{-5}$ [reduce the fraction]

Hopefully this is helpful enough to get you to your answer
