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

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

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

Which graph represents a linear function?
On a coordinate plane, a parabola opens down.
On a coordinate plane, a line has a negative slope.
On a coordinate plane, a line curves up.
On a coordinate plane, a line curves down, levels off, and then curves down.
Answer:
On a coordinate plane, a line has a negative slope
Step-by-step explanation:
A linear function is a function whose graph is a straight line. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function.
Thanks to everyone who helped me with the previous questions
Last question:
Answer:
y=-3x+7
Step-by-step explanation:
Rise/run
To find slope you can use the rise/run strategy. You count how many units up/down and then how many right/left. between each point on the line, it was down 3 units, right 1 unit (3/1) and since it was going down it would be negative.
As for the y-intercept, you look at where the line crosses the y-axis. In this case it was at (0,7), so the answer would be 7.
Plug your answers in and your equation should be y=-3+7.
You could also do y=7-3x, its the same equation but reversed, so you'll get the same line.
Hope this helps :)
