(4^2 - 8 +2 * 10) / ( 3^2 - 5)
(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
28/4= 7

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
Answer = 2x - 30
50 POINTS PLS HELP | The line segment graphed on the coordinate plane represents a roof with several triangular supports. Each support is triangular, with a horizontal board that starts on the edge of the roof and connects with a vertical board that ends on the edge of the roof as shown.
Does each support have the same starting coordinates? Explain.
Does each support have the same ending coordinates? Explain.
Does each support have the same change in x-values? Explain.
Does each support have the same change in y-values? Explain.
Does each support have the same ratio of change in y-values over change in x-values? Explain.
a) No, clearly the starting points are different for each support: (0,0) is not ((2,1), etc.
b) No, similar to a) answer: (2,1) is not (6,3) etc
c) No, 2 does not equal 4, etc.
d) No, 1 does not equal 2, etc.
e) Yes, this is just the slope of the diagonal line: 1/2 = 2/4

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°.

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

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
