Solve using the order of operations. (9+9+72)-4+9
PLZ ANSWER PLZ HURRY
Answer:
95
Step-by-step explanation:
The order of operations is PEMDAS
Equations in PARENTHESES come first
Numbers with EXPONENTS come second
MULTIPLICATION/DIVISION problems come next (depending on which comes first in the equation
ADDITION/SUBTRACTION comes last (again, depending on which comes first in the equation)
So we do (9+9+72) first
So that equals 90
And then we subtract 4 from 90
90 - 4 = 86
Then we add 9 to 86
86 + 9 = 95
Answer: 72 is the answer

To compute the perimeter of a rectangle, you add the length, l , and width, w , and double this sum.
This means you can find the perimeter of a rectangle by evaluating the expression 2 (1 + w ).
Use this expression to find the perimeter of a rectangle with length 30 and width 75.
210 (A)
135 (B)
180 (C)
107 (D)
Answer:
210 (A)Step-by-step explanation:
Use the formula:
P = 2(l + w)Substitute the values and find P:
P = 2(30 +75) = 2(105) = 210Correct choice is A
Answer:
given length [l]=30
width[w]=75
perimeter= 2 (l + w )=2(30+75)=210
so
answer is A.210

A group of friends wants to go to the amusement park. They have no more than $175 to spend on parking and admission. Parking is $12.50, and tickets cost $16.25 per person, including tax. Write and solve an inequality which can be used to determine xx, the number of people who can go to the amusement park.
Answer:
10 people can go to the amusement park
Step-by-step explanation:
$175-$12.50 = $162.50
$162.50 divided by $16.25= 10

help me please don't understand (see picture)
Answer:
< F would be 140 degrees
Step-by-step explanation:
So what you would do is that since they told you angle D is 40 degrees and you know that the 2 lines in there are parallel, and since they are asking for angle F, whne you add angle F and angle H they should equal 180 degrees which you know so you just subtract 40 degrees from 180 and you get 140 degrees which if angle F and you can subtract 40 since angle H and angle D would be congruent.
How much higher is the average cost at a clinic

Step-by-step explanation:
-x+y = 5
x - 5y = -9
Solve by elimination
Y and x
Answer:
x = -4 and y = 1
Step-by-step explanation:
-x + y = 5
+ x - 5y = -9 <— let’s eliminate x
————————————-
-4y = -4
y = 1
x - 5y = -9 <— substitute for y
x - 5(1) = -9
x - 5 = -9
+5 = +5
x = -4
What is the mean of the data set?
29, 26, 35, 34
the mean of that set is 31
Answer:
31
Step-by-step explanation:
Add all the numbers:
29 + 26 + 35 + 34 = 124
Divide by 4 (because there are 4 total numbers):
124/4 = 31

Order the following from LEAST to GREATEST: -0.9, -4/5, -1/4, -1/2, -7/10
-0.9, -4/5, -7/10, -1/2, -1/4
Answer:
The answer is -0.9, -4/5, -7/10, -1/2, -1/4.
Step-by-step explanation:
-4/5 = -0.80
-7/10 = -0.7
-1/2 = -0.5
-1/4 = -0.25
3х - 30 = у
7y - 6 = 3х
Answer:
Step-by-step explanation:
This one is simple substitution... at least, substitution is the easiest method. The first equation is 3x – 30 = y and the second is 7y – 6 = 3x
As I look, I see 3 ways to use substitution to solve this:
substitute 7y – 6 for 3xsubstitute 3x – 30 for ysolve 3x – 30 = y for 3x and make it equal to 7y – 6We're going to only use 1 method for the sake of time. Try the other two on your own. Assuming you don't make any mistakes, they will work.
Method 1:
3x – 30 = y
7y – 6 = 3x — initial system of equations
7y – 6 – 30 = y — substitute 7y – 6 for 3x
7y – 6 – 30 = y — marking like terms, bold for constants, underlined for variables
7y – 36 = y — combining the constants and simplifying
Here, you could diverge into multiple paths: add 36 to both sides, subtract y from both sides, divide by 6 OR subtract 7y from both sides and divide by –6 . For the sake of time, I'm subtracting 7y, though I don't like dealing with negatives.
7y – 7y – 36 = y – 7y — subtract 7y from both sides
–36 = –6y — simplify
–36 ÷ –6 = –6y ÷ –6 — divide by –6 on both sides
y = 6 — simplify
Again, we can diverge here: substitute y into 3x – 30 = y or substitute y into 7y – 6 = 3x
I'm going to choose 3x – 30 = y but it will work either way, should you take the time (if you have it) to chase down every path this problem can take.
3x – 30 = y — initial equation
3x – 30 = 6 — substitute 6 for y
3x – 30 + 30 = 6 + 30 — add 30 to both sides to isolate 3x
3x = 36 — simplify the expression
3x ÷ 3 = 36 ÷ 3 — divide both sides by 3 to isolate x
x = 12 — simplify
So, we have x = 12 and y = 6 . We know they work for 3x – 30 = y but not if they work for 7y – 6 = 3x . Let's substitute those in to see if (12, 6) really is the solution point.
7y – 6 = 3x — original equation
7(6) – 6 ≟ 3(12) — substitute 6 for y and 12 for x
42 – 6 ≟ 36 — simplify by multiplying
36 = 36 ✔ — simplify by combining like terms on left side
Success! It works! We have found our solution!
I hope this helps increase your understanding of the concept. Have a great day!

Step-by-step explanation:
An online furniture store sells chairs for $150 each and tables for $400 each. The store must sell a minimum of $4900 worth of chairs and tables each day. Write an inequality that could represent the possible values for the number of tables sold, tt, and the number of chairs sold, cc, that would satisfy the constraint.
Answer: 150c + 400t ≥ 4900
Step-by-step explanation:
Let the number of chairs sold = c
Let the number of tables sold = t
Price for each chair = $150
Price for each table = $400
The inequality that could represent the number of tables and chairs sold will be:
(150 × c) + (400 × t) ≥ 4900
150c + 400t ≥ 4900

help i didnt learn anything the method is distance
Answer:
10 units
Step-by-step explanation:
Of course you have to graph the two points to find out the answer.
Then you count the units or squares to find out how far they are.
So it was basically 6 units to the right and 4 units up :)
Hope this helped plz mark brainliest :))
6x-y=1 convert the standard form to a slope intercept.
Answer:
y= 6x-1
Step-by-step explanation:
6x-y=1
-y= -6x+1 (move x over to the right side)
y= 6x-1 (divide both sides by -1)

A tank that holds up 10 gallons. when its active, a drain empties water from the tank at a constant rate, when Jada first see the tank, it contains 7 gallons of water. three minute later the tank contains five gallons of water.
At what constant/rate is the amount of water changing in the tank?
Answer:
-2/3 gallon/minute
Step-by-step explanation:
In three minutes the water volume has decreased by 2 gallons (7 less 5 is 2). The unit rate of decrease of the amount of water in the tank is thus:
- 2 gallons
------------------- = -2/3 gallon/minute
3 minutes
