To find the sales tax you’d need to find 9% of 87. You find this by using this template, x%/100%=y/z, x being the sales tax, y being 9% in cash, and z being the 87 dollars. You multiply the x value by the z value, (9 X 87=783) and then divide that product by 100%. This gives you the sales tax of 7.83, and when you add that to 87 you get $94.83. Subtract that from the 5 20 dollar bills ($100) and you are left with $5.27 change.
When using factoring by grouping, the replacement terms will both have the same sign of the original middle term. If the last term is negative, then the signs of the factors will have one of each sign with the “stronger” number (the larger absolute value) matching the middle term. hope this helps
The correct Set-builder form of the set that is written in Roster form is {x|x is an integer and -3≤x≤1}.
<h3>What is an integer?</h3>
An integer is a number that can be written without using a fractional component. Integers such as 21, 4, 0, and 2048 are examples.
The correct Set-builder form of the set that is written in Roster form can be written as,
{x|x is an integer and -3≤x≤1}
Hence, The correct Set-builder form of the set that is written in Roster form is {x|x is an integer and -3≤x≤1}.

To check if x = 9 is the solution, we need to replace every x with 9 and simplify
(3+x)/4 = 3
(3+9)/4 = 3
12/4 = 3
3 = 3
We get the same thing on both sides, so the last equation is a true equation. This means that the first equation is a true equation when x = 9. Therefore, the solution x = 9 is confirmed.
Answer: Yes, it is less than, as the value of the first equation is 14, while the second equation is 100.8
Step-by-step explanation:
1.7y + 37 = 14...........equation 1
9.3y - 25 = ?............equation 2
Find the value of y by subtracting 37 from both sides of equation 1
1.7y +37 -37 = 14 - 37
1.7y = -23
Divide both sides by 1.7
y = 13.53
Insert the value of y into equation 2
9.3 (13.53) - 25
125.83 -25
=100.8
