Thomas bought 6 glass cups and 6 plastic cups
How to calculate the number of glass and plastic cups ?
Thomas bought 12 glass and plastic cups from the store
Glass cups costs $3.25
Plastic cups cost $2.75
He spent a total of $36
Let g represent the number of glass cups and p represent the number of plastic cups
g + p= 12.........equation 1
3.25g + 2.75p= 36..........equation 2
From equation 1
g+p= 12
g= 12-p2
Substitute 12-p for g in equation 2
3.25(12-p)+2.75p = 36
39-3.25p+2.75p= 36
39-0.5p= 36
-0.5p= 36-39
-0.5p= -3
p= -3/-0.5
p= 6
Substitute 6 for p in equation 1
g + 6= 12
g= 12-6
g= 6
Hence there are 6 glass cups and 6 plastic cups

Question 3(Multiple Choice Worth 2 points) (Order of Operations with Radicals LC) Simplify the expression. 20(6) − 7 113 20 −20 −113
The simplified value of the expression will be -824.
What is algebraic expression ?
An algebraic expression in mathematics is made up of variables, constants and operations such as addition, subtraction, etc.
Given that the expression is 20 × (6) − (7 × 113 × - 20) − 20 − 113.
Now , we will simplify the above expression using PEMDAS rule , which follows the order that is parentheses, exponents, multiplication, division, addition, subtraction.
So , if we solve the expression we will get ,
= (20 × 6) − (7 × 113) - 20 − 20 − 113
Firstly , solve terms which are in parentheses.
= 120 - 791 - 20 - 20 - 113
Now , we will add all the negative terms.
= 120 - 944
Now , subtracting both numbers.
= -824
Thus , the simplified value is equal to -824.

Compute 5DBE16-9AF416 using 2’s complement, leave your final answer in octal
5DBE16-9AF416 using 2’s complement is -2635716 octal.
We need to compute 5DBE16-9AF416 using 2’s complement, leave your final answer in octal.
What is two's complement?When two's supplement is utilized to address negative numbers, the main piece (MSB) is used to show the indication of the number. A 1 in the MSB position shows a negative number, and a 0 in the MSB position demonstrates a positive number. In two's supplement, negative numbers are addressed by the converse of the positive number in addition to 1.
To find the backwards of a number, every digit is just upset - 0 changes to 1, and 1 changes to 0. In this way, the converse of 5DBE16 is A2416. One is added to the opposite to find the two's supplements giving us A2417.
2's supplement of a number=the numbers supplement+1
5DBE16-9AF416=464416-9AF416=-54AF416+1=-54AF416
The two's supplement of a number can be determined by deducting the number from 2^n, where n is the number of pieces used to address the number. Along these lines, for this situation, we would take away 5DBE16 from 2^32, which gives us 464416.
Since the 2's complement of a number is equivalent to the negative, we can say that 5DBE16-9AF416=-54AF416.
To change over a two's supplement number to octal, we can involve a similar technique as we would use to switch a paired number over completely to the total. We bunch the pieces into three sets, beginning from the right, and convert each gathering into an octal digit.
In this way, the 2's supplements of 5DBE16-9AF416 would be composed as continues in octal 464416-9AF416=-2635716 octal
Therefore, 5DBE16-9AF416 using 2’s complement is -2635716 octal.

step by step aswell please
The solution for x from the linear equation is x=(n+p)/m .
Linear equation is a equation where the greatest degree of the variable is 1 in the equation.
A basic linear equation in the variable x is of the form ax+b =0 where b is a constant and a is the co-efficient of x.
To solve a linear equation for x we use the simple mathematical operations to make x the subject of the formula.
Given equation is:
mx=n+p
We have to find the value of x.
So we can see that the variable x has a constant co-efficient m
to make x the subject we divide both sides of the equation by m.
Therefore:
mx÷m=(n+p)÷m
or, x=(n+p)/m
So on solving the linear equation we get the value of x as (n+p)/m

Chen says the product of 4x0 is the same as the sum of 4+0. Is Chen correct? Explain.
Answer:
No
Step-by-step explanation:
The product of zero and any number is zero. Basically, if you multiply any number with zero, you get zero. Hence, 4*0=0. However, anything added with zero is itself since you're basically not adding anything to that number. For example, nothing is being added to 4 in '4+0', so 4+0=4.
