Answer:
Tax = $0.75
Tip = $2.25
Total (meal + tax + tip)= $18.00
Step-by-step explanation:
When solving for percentages of a number, such as sale tax and tip, multiplying the decimal equivalent of each percentage to the amount will give you the individual costs. For example, in this case the sales tax is 5%, the decimal equivalent of 5% = 5 ÷ 100 = 0.05. To find the amount of tax on Allam's meal, multiply the rate by the amount:
0.05 x $15 = $0.75
Since he plans to leave a 15% tip, we can also multiply the amount of the meal by the planned tip amount:
15 ÷ 100 = 0.15
0.15 x $15 = $2.25
Total amount paid, including tax and tip:
$15 + $0.75 + $2.25 = $18.00
Y = 4x - 1
// Plug this in for variable y in equation [1]
[1] 20x - 5•(4x-1) = 5
[1] 0 = 0 => Infinitely many solutions
Answer:

Step-by-step explanation:
The division problem given to us is
.
To perform the synthetic division, we write out the coefficient of the polynomial. We set the linear factor to zero and solve for x, this becomes our divisor. That is
.
We carry out the synthetic division as shown in the attachment.
The result of the synthetic division is 4 -27 167 -996
The first three terms are the coefficients of the quotient and the last term is the remainder.
Therefore the quotient is
and the remainder is
.
The dividend, the quotient and the divisor are written as
