if (93 x p) + 84 = 85 then please equals:
0
1/93
1/85
1/84
1
Using the principle of solving algebraic expressions, the value of p in the equation is 1/93
Given the expression :
(93 × p) + 84 = 85Solving the expression in bracket :
93p + 84 = 85
Subtract 84 from both sides to isolate 93p
93p + 84 - 84 = 85 - 84
93p = 1
Divide both sides by 93 to isolate p
93p/93 = 1/93
p = 1/93
Therefore, the value of p in the expression is 1/93.

What is 76912 divided by 92
Solve for x. y=7x−7z−9
Answer:
The value of x is [tex]x=\frac{y+7z+9}{7}[/tex]
Step-by-step explanation:
Consider the provided equation.
[tex]y=7x-7z-9[/tex]
We need to solve the equation for x.
Add 7z to both the sides.
[tex]y+7z=7x-7z+7z-9[/tex]
[tex]y+7z=7x-9[/tex]
Add 9 to both the sides.
[tex]y+7z+9=7x-9+9[/tex]
[tex]y+7z+9=7x[/tex]
Divide both sides by 7.
[tex]x=\frac{y+7z+9}{7}[/tex]
Hence the value of x is [tex]x=\frac{y+7z+9}{7}[/tex].

In a school, there are 150 students. Out of these 80 students enrolled for mathematics class, 50
enrolled for English class, 60 enrolled for physics class. The student enrolled for English cannot
attend any other class , but student of mathematics and physics can take two courses at a
time. Find the number of students who have taken both physics and mathematics.
a. 40
b. 30
c. 50
d. 20
By applying set theory, we calculate that 40 students are enrolled in both mathematics and physics classes after excluding the 50 English students who cannot attend any other classes.
Explanation:To find the number of students who have taken both physics and mathematics, we can subtract the number of English class students from the total because they cannot be in the group that takes both of the other two classes.
So, we have a total number of students who can take math or physics, which is 150 - 50 = 100 students.
Since there are 80 students in mathematics and 60 in physics, the maximum number could be 80 if every physics student also took mathematics.
But because we only have 100 students to distribute between the two subjects (excluding the English students).
The actual number of students who took both courses will be the total number for math and physics classes (80 + 60) minus the number of students who can take these classes, which gives us ;
140 - 100 = 40 students.
Therefore, the answer is 40 students have taken both physics and mathematics classes. This corresponds to choice a.

Ernesto's bus arrived 51 minutes after he got to the bus stop. Determine what fraction of an hour Ernesto spent waiting for the bus. Write the fraction in the simplest form.
17/20 is the fraction of an hour Ernesto spent waiting for the bus
What is Fraction?A fraction represents a part of a whole.
Given that Ernesto's bus arrived 51 minutes after he got to the bus stop
We need to find the fraction of an hour Ernesto spent waiting for the bus
We know that 1 hour has 60 minutes.
Ernesto's waited 51 minutes out of 60 minutes or an hour.
So 51 minutes is the part and 60 minutes is the whole part
Then the fraction will be 51/60
51 and 60 are the multiples of 3.
Let us divide numerator and denominator by 3
17/20
Hence, 17/20 is the fraction of an hour Ernesto spent waiting for the bus

Patel squeezed oranges so that his family could have fresh-squeezed juice for breakfast. He squeezed 4/17 cups from the first orange, 3/10 cups from the second orange, 9/20 cups from the third orange, 3/11 cups from the fourth orange, and 7/15 cups from the fifth orange. Patel estimates that he needs 2 cups of orange juice for his family. About how much more orange juice does he need?
The amount of juice needed is about 0.487 cups
Amount of oranges squeezed :
First orange = 4/17 cups
Second orange = 3/10 cups
Third orange = 9/20 cups
Fourth orange = 3/11 cups
Fifth orange = 7/15 cups
Total amount of oranges needed = 2 cups
The amount of extra orange needed = x
Adding :
(4/17 + 3/10 + 9/20 + 3/11 + 7/15) + x = 2
(13200 + 168300 + 252450 + 153000 + 261800) / 561000
(848750 / 561000) + x = 2
1.5129 + x = 2
x = 2 - 1.5129
x = 0.4871 cups
The amount of juice needed is about 0.487 cups

An investment is currently worth 1.035×108 dollars . Thirty years ago, the investment was worth 2.3×105 dollars. How many times greater is the value of the investment today than the value of the investment thirty years ago? A. 0.45 B.450 C.4500 D. 45,000
The correct option is: B. 450
Explanation
Current value of the investment is [tex]1.035\times 10^8[/tex] dollars and 30 years ago, the value of the investment was [tex]2.3\times 10^5[/tex] dollars.
Suppose, the value of investment today is [tex]n[/tex] times greater than the value of the investment thirty years ago.
So, the equation will be........
[tex]n(2.3\times 10^5)=1.035\times 10^8\\ \\ n= \frac{1.035\times 10^8}{2.3\times 10^5}=0.45\times 10^3 = 450[/tex]
Thus, the value of the investment today is 450 times greater than the value of the investment thirty years ago.
Answer: B. 450
Step-by-step explanation:
Given: An investment is currently worth =[tex]1.035\times10^8[/tex] dollars .
Thirty years ago, the investment was worth =[tex] 2.3\times10^5[/tex] dollars.
Now, the number of times the value of the investment today than the value of the investment thirty years ago is given by :-
[tex]n=\frac{1.035\times10^8}{2.3\times10^5}\\\\=0.45\times10^{8-5}........\text{Since }a^na^m=a^{m+n}\\\\=0.45\times10^3\\\\=0.45\times1000=450[/tex]
Hence, the value of the investment today is 450 times greater than the value of the investment thirty years ago.

A patrol unit has 13-gallon fuel tank and averages 15 miles per gallon of fuel used. If the officer assigned to the unit works four 10-hour shifts per week and typically drives 100 miles per shift. How much fuel will the officer's unit use in one week?
The officer's unit will use approximately 26.67 gallons of fuel in one week.
Explanation:To calculate the amount of fuel the officer's unit will use in one week, we need to determine the total distance driven in a week and then calculate the amount of fuel needed for that distance.
Since the officer works four 10-hour shifts per week, the total driving time in a week is 40 hours (4 shifts x 10 hours per shift). If the officer typically drives 100 miles per shift, then the total distance driven in a week is 400 miles (100 miles per shift x 4 shifts).
Now, let's calculate the amount of fuel needed for 400 miles at an average fuel economy of 15 miles per gallon.
Fuel used = Total distance driven / Fuel economy = 400 miles / 15 miles per gallon
Fuel used = 26.67 gallons
Therefore, the officer's unit will use approximately 26.67 gallons of fuel in one week.
