You must have learned "Order of Operations" or PEMDAS by now,
because that's what this whole question is talking about.
Look at the one in the first box:
32 ÷ 4² + 35 - 20 ÷ 5
You know how to do 4², and you know how to do 20÷5, and you know
how to do 4²+35, and you know how to do 35-20 .
But which one should you do first ? ! ?
pEmdas . . . do exponents. 4² = 16
Now you have 32÷16 + 35 - 20÷5
pemDas . . . do division. 32÷16 = 2
and 20÷5 = 4
Now you have 2 + 35 - 4
pemdAs . . . do addition: 2 + 35 = 37
Now you have 37 - 4
pendaS . . . Do subtraction: 37 - 4 = 33 .
That's the whole ugly thing in the first box. It's 33 .
Do the other two boxes the same way. Then you'll have a single number
for each box. Then just line up the three numbers in the order of their size.
This is all just one big PEMDAS exercise. If you do the operations in the
wrong order in one of the boxes, then you'll get the wrong number in that box.

Answer:
x = 18-(0.25×18)
Step-by-step explanation:
The price of the pillow = $18.00
cost is marked down = 25% = = 0.25
Let the new price be x
The expression that can be used to find the new price of the pillow will be
x = 18-(0.25×18)
n= new price
n=18-(18*0.25)

Answer:
Step-by-step explanation:
When you have an inequality like this, you can treat it like an equation except for one part. If you ever divide or multiply it by a negative number or variable you have to flip the inequality. if it is equal to as well you keep that though. for instance
-5x ≤ 10
x ≥ -2
Anyway, in your case you have two inequalities, so you have to solve both and see what makes both true.
We'll start with 12x - 39 ≤ 9
12x - 39 ≤ 9 First add 39 to both sides
12x ≤ 48 Now divide both sides by 12, positive so no flipping
x ≤ 4
Next is:
-4x + 3 < -6 First subtract 3 from both sides
-4x < -9 Now divide both sides by -4, which means the sign flips
x > 9/4
Now, without even looking at the answers, what number or numbers are less than or equal to 4 and greater than 9/4? Well we pretty much described it there. All numbers starting from, though not including 9/4, which is 2.25, all the way up to, and including 4. B shows exactly that.
Final answer:
To solve the inequalities, the first is simplified to x > 4 and the second to x > 2.25 after applying proper arithmetic operations and considering the signs during division.
Explanation:
The student's question involves solving two inequalities, one of which is a linear inequality, and the other an inequality that requires adding or subtracting to isolate the variable. To solve the inequality 12x - 39 > 9, we add 39 to both sides to get 12x > 48, then divide both sides by 12 to find that x > 4. For the inequality -4x + 3 < -6, we subtract 3 from both sides to get -4x < -9, then divide by -4, remembering that dividing by a negative number reverses the inequality, resulting in x > 9/4 or x > 2.25.
