15% = 0.15
multiply the bill ( 42.00) by 0.15 for the amount of tip
42.00 * 0.15 = 6.30
the tip = $6.30
Answer:
A rational number is any number that can be written as a ratio of two integers (hence the name!). In other words, a number is rational if we can write it as a fraction where the numerator and denominator are both integers. ... Irrational, then, just means all the numbers that aren't rational.
Step-by-step explanation:

1.5 is the slope of the function
For a deferred payment plan no interest is accrued for the deferment period.
If $85 is made each month, then in 18 months, 18 * 85 = $1,530 must have been paid off from the balance owed.
Thus, the remaining balance after the deferment period is $2,885 - $1,530 = $1,355.
Answer:
x=√3
Step-by-step explanation:
Let's solve your equation step-by-step.
3x2+3x−2=3x+7
Step 1: Subtract 3x from both sides.
3x2+3x−2−3x=3x+7−3x
3x2−2=7
Step 2: Add 2 to both sides.
3x2−2+2=7+2
3x2=9
Step 3: Divide both sides by 3.
3x2
3
=
9
3
x2=3
Step 4: Take square root.
x=±√3
x=√3 or x=−√3
