FINAL ROUND!! Could someone please help answer this thanks so much, please no spam, will give brainliest (homework help)
Answer:
a is less than or equal to 7
Step-by-step explanation:
This is the case because we can treat the less than or equal to sign as an equal sign. The only time it changes is when we divide by a negative, but we do not do that in this problem. First, you subtract 7 from both sides. That leaves us with a 4a on one side and a 28 on the other. Then, you divide both sides by four to get a is less than or equal to 7. I hope this helps!
The price of a dress was reduced from $40 to $30. By what percentage was the price of the dress reduced? STEP BY STEP
Answer:
The price was reduced by 25%
Step-by-step explanation:
Not sure how to go step by step on this, because it's kinda obvious once you think about it a bit. You need to find what percent of 40 that 10 equals (if that makes sense). So really it's just what percent of 40 equals 10? and since 10 is one fourth of forty, 1/4, then you convert that to percent: 25% (sorry if this made no sense, i'm not very good at explaining things)

i need help, how do you do this
Answer: So you are going to make an equation first.
Step-by-step explanation:
first we know that for the first 2 hours the snow fell at an inch an hour. so we are going to make our first plots ( I suggest using an online site like geogebra or desmos to start out with before plotting for your assingment)
our first plot is going to be at (1,1) or 1 over and 1 up. remember points are in the form of (x,y). then (2,2)
Now we see that it has changed now there is no new snow for 6 hours so you are going to have a flat line so its going to be (2,2) then its going to continue that way as (3,2),(4,2), (5,2) (6,2)(7,2)(8,2).
It starts snowing again and now we have a new thing to plot the snow is falling at a constant of 3 inches an hour for the next 5 hours so now we are going to plot hte points to get our points we are going add 3 inches to our current inches each new hour. so its going to be (9,(2+3)) which is (9,5) and continue on doing that so we will have the plots (10,8) (11,11) (12,14) (13,17). and now we connect our plots by creating segments so then you do that on your thing and youre set to go I hope this helps.

6. Write the statements "If you take away 6 from 6 time a number, you get
60” in the form of equations:
(a) 6x + 6 = 60
(b) 6x6 = 60
(c) X-6 = 60
(d) none of these
Answer:
6x-6=60 so if you correctly typed the question its none of them

It costs a company $20 per box to make pocket-sized stuffed animals. The company also has a fixed manufacturing cost of $2300. The owners are trying to calculate their cost for making boxes of animals.
Find the slope of the line.
Answer:
The slope is y = x
Step-by-step explanation:
You can find the slope by using the rise over run method with two points.Let's take (1,1) and (2,2). From the first point to the second point, (1,1) goes up one unit and to the right one unit.So the rise over run is 1/1, or 1, which means the slope is 1.
Answer:
m = 1x
Step-by-step explanation:
This is the easiest slope you'll ever have to calculate - if you even need to as it's self explanatory looking at it! Slope = rise/run, thus slope = 1/1 = 1.

What triangle can be formed with angle measures of 32,126,and 32
Answer:
Yes.
Step-by-step explanation:
32 + 32 + 126 = 180
This means that a triangle can be formed, as the angles add up to 180°.
Which set of angle measures could be the measures of the interior angles of a triangle?
60°, 45°, and 70°
30°, 85°, and 25°
55°, 90°, and 35°
119°, 15°, and 45°
Answer:
55°,90°,35°
Step-by-step explanation:
the sum of interior in a triangle is 180° and 55 +90+35=180
Which of the following best describes the slope of the line below?
O A. Zero
B. Negative
C. Positive
D Undefined
If you look at the graph, you will realize that it is highest to the left and lowest to the right and that as x increases, the y decreases, and when x decreases, y increases. Thus it has a NEGATIVE slope.

Line segment AB is a Translation of line segment CD 6 units down. Drag line segment CD and try to move it onto line segment AB. Are line segment AB and CD the same? What does this mean about how the line segment changes when you translate it?
Answer:
Only the position changes with translation. Other measures, including slope and length, remain the same.
Step-by-step explanation:
Line segment CD can be placed directly on top of line segment AB. The translated segment has the same length and orientation as the original
