(P) E M D A S
Solve inside of perithesis first:
((4^2) - 8 +2 * 10) / ((3^2) - 5)
P (E) M D A S
4^2 = 16 , & 3^2= 9
Plug in:
(16 - 8 + 2 * 10) / (9 - 5)
P E (M) D A S
2*10= 20
Plug in:
(16 - 8 + 20) / (9 - 5)
P E M D (A S)
in order from left to right:
16-8=8, 8+20=(28)
&
9-5=(4)
Plug in:
28 / 4
P E M D A S

a girl scout has (5x-12) boxes of cookies and sells (3x+18) of them. Write an expression to represent the amount of boxes she has left. i need help.
Answer:
2x - 30
Step-by-step explanation:
You have to subtract 3x + 18 from 5x - 12:
=> 5x - 12 - ( 3x + 18) = 5x - 12 - 3x - 18 = 5x - 3x - 12 - 18 = 2x - 30
The first step was to apply distributive properties to get rid of the parenthesis, after that the terms were arranged and the like terms combined

Referring to the figure, a building casts a
shawdow 18 feet long. A woman standing near the
building is 5 feet 8 inches tall and casts a
shadow 4 feet long. What is the height of the
building in feet and inches?
Answer:
18/4 = x/(5 2/3)
x = 18(17/3)(1/4) = 25 1/2 ft. = 25 ft 6 in.
Which number sentence represents the Commutative Property of Addition?
44 + 1 = 45
44 + 1 = 45
(16 + 2) + 18 = 16 + (2 + 18)
(16 + 2) + 18 = 16 + (2 + 18)
56 + 0 = 56
56 + 0 = 56
32 + 9 = 9 + 32
The number which represent represents the Commutative Property of Addition will be;
⇒ 32 + 9 = 9 + 32
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expressions are,
44 + 1 = 45
44 + 1 = 45
(16 + 2) + 18 = 16 + (2 + 18)
(16 + 2) + 18 = 16 + (2 + 18)
56 + 0 = 56
56 + 0 = 56
32 + 9 = 9 + 32
Now,
We know that;
The rule of the Commutative Property of Addition is,
⇒ a + b = b + a
Hence, The correct number which represents the Commutative Property of Addition is,
⇒ 32 + 9 = 9 + 32

If l || m, m7 = 2x and m2 = x, then what is the measure of angle 2?
90°
30°
120°
60°
An l || m, m7 = 2x and m2 = x, then what is the measure of angle 2 is 30°.
To find the measure of angle 2, use the properties of parallel lines and transversals.
Given that line l is parallel to line m, and we have two angles formed by a transversal intersecting these lines, angles 2 and 7.
are given that m7 = 2x and m2 = -1.
Since lines l and m are parallel, alternate interior angles are congruent. Therefore, angle 2 and angle 7 are congruent.
m2 = m7 (alternate interior angles are congruent)
Since m7 = 2x, substitute:
m2 = 2x
But, we are also given that m2 = -1, so set up an equation:
-1 = 2x
Now, solve for x:
x = -1/2
Now that have the value of x, find the measure of angle 2:
m2 = 2x
m2 = 2(-1/2)
m2 = -1
Therefore, the measure of angle 2 is -1 degree. However, it's worth noting that angles are typically measured as positive values, so the answer in this case would be 1 degree (considered as an acute angle). None of the multiple-choice options provided matches this answer exactly, but the closest one would be 30°.

8th grade math!! need to get a good grade!
Answer:
Bonnie :
(0,12),(1,16)
Slope = (16 - 12) / (1 - 0) = 4/1 = 4
So Bonnie is adding $ 4 every week to her savings
Bobby :
y = 12x + 4
The slope here is 12.....so he is adding $ 12 every week to his savings
Therefore, the rate at which Bobbie is adding to his savings each week is (12 - 4) = $ 8 more then the rate at which Bonnie is adding to her savings account each week
