Answer:
Subtract 3
Step-by-step explanation:
The first operation that should be done first in the expression 5x + 3 = 28 is subtracting 3 from both sides.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, 5x + 3 = 28.
The first operation that should be done first is subtracting 3 to both the side of the equation to separate the variable x and the constant term.
∴ 5x + 3 - 3 = 28 - 3.
5x = 25.
x = 5.

Solve for x in the literal equation −5 = xy + z.
Answer: x = -5 -z/y or x= -5/y - z/y
Step-by-step explanation:
-5 = xy + z -- then you need to isolate the x, so subtract z from both sides
-5-z = xy -- then divide both sides by y
x= -5-z/y

After the bank cashed a check Maureen wrote for $60, her balance was Negative 14 dollars. The equation b + (negative 60) = negative 14 can be used to represent this situation, where b is Maureen’s balance, in dollars, before the check was cashed. Maureen attempted to solve the equation using the steps below.
Maureen should have added 60 to both sides.
is the answer ^^
Answer:

Complete question:
At the beginning of the day the stock market goes down 30 3/4 points and stays at this level for most of the day. At the end of the day the stock market goes up 100 1/2 points from the low at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the day?
Answer:
The total change in the stock market is [tex]69\frac{3}{4}[/tex]
Step-by-step explanation:
Given;
the stock market at the beginning of the day = 30 3/4 points
the stock market at the end of the day = 100 1/2 points
The total change in the stock market from the beginning of the day to the end of the day is given by;
100 1/2 points - 30 3/4 points
[tex]= (100 -30) + (\frac{1}{2} -\frac{3}{4} )\\\\= 70 + (-\frac{1}{4} )\\\\= 70 - \frac{1}{4}\\\\= 69\frac{3}{4}[/tex]
Therefore, the total change in the stock market is [tex]69\frac{3}{4}[/tex]

15 men can do a piece of work in 80 days. If 5 more men are added, how long will it take to complete same piece of work?
Answer:
Step-by-step explanation:
This is an inverse proportion.
men = k / Time So first we need to find k
k = men * Time Substitute values
k = 15*80
k = 1200 Notice the units are man days.
Now what happens if we increase the number of men to 20? What happens to the number of days.
20 = 1200 / time Multiply both sides by time
20*time = 1200 Now divide by 20
time = 1200/20
Answer: time = 60 days
