Step-by-step explanation:
1. subract 8 from both sides to get b/-4=-3
multiply both sides by -4 to isolate b
you get b=12
2. combine like terms 3c-4=-8+2c
add 4 to both sides: 3c = -4+2c
subtract 2c from both sides
c=-4
2. C -4
Both C

Answer:
I got u fam any questions? hit me up
Step-by-step explanation:
so you're learning about plotting graphs. If the hot female lifeguard makes 8.50 an hour, then the table would be 1 in the hours place and 8.50 in the money's place. Then for hour number 2, you multiply 8.5 by 2 and you get 17.
When you plot the numbers on the x-axis (horizontal line in the graph) label the intervals by 1s so 1, 2, 3, 4, etc. for the y-axis (vertical line in the graph), start by 2, then go by intervals of 2 which would be 2, 4, 6, 8, 10, etc. Now, when u plot the points, label the x axis "hours" because that is the independent quantity and the money is dependant on the number of hours, so label "dollars made" on the y-axis. From the table you will have (1, 8.5) which will be your first point and plot it in the graph use this as a reference
(x coordinate, y coordinate) the one on the right will always be the y coordinate and the one on the left will always be the x coordinate. Draw the line from (0,0) to (1, 8.5) so go up 8.5 in numbers and right 1 and keep drawing until you reach the end of the graph. Number 4 would be 2x+1. when u see f(2), that means to replace x with the number in the parentheses which would be 2(2)+1=5

Why does the sum of the two given angles equal 180°? (2x+1)+(x-7)=180
Answers
Answer:
because its a straight line
Step-by-step explanation:
Answer:
Since the sum of the angles is 180 degrees and each angle is represented by the respective algebraic expressions, then to find the value of x, just add the expressions up, set that sum equal to 180, and solve for x. So, (2x-7)+(x+25)+(3x+12)=180 is our equation. Now we just simplify and solve for x.
(2x-7)+(x+25)+(3x+12)=180
6x+30=180 b/c 2x+x+3x=6x and -7+25+12=30.
6x=150 subtract 30 from both sides of the equation
x=25.

For the 6th annual school fundraiser, Daisy needs to sell 38 rolls of
wrapping paper. So far, she has sold 2.24 rolls to her grandmother, 5.75
rolls to her uncle, and .6 rolls to a neighbor. How many more rolls of
wrapping paper does Daisy need to sell? If each roll costs $3.46, how
much money can Daisy make?
Answers
Answer:
She needs to sell the rest of her 29.41 rolls of wrapping paper. If she sells all of her rolls of wrapping paper, she'll be able to get a total of $131.48.
Step-by-step explanation:
To get the answer to "How many more rolls of wrapping paper does Daisy need to sell?" you would have to add up how many she already sold which is
2.24 + 5.75 + 0.6 = 8.59
and then subtract 8.59 from the total of rolls she's supposed to sell.
38 - 8.59 = 29.41
To get $131.48
You multiply how much each roll costs to the total of rolls she's supposed to sell:
38 * 3.46 = 131.48

Scientists sometimes use analogies, or comparisons to other ideas and objects, to explain the nature of science. Are scientific ideas MORE like a piece of glass or a piece of aluminum foil?
Answers
Answer:
Step-by-step explanation:
How about both?
Glass permits you to see what is going on inside a closed container. Usually it is microscopic view of something that is very tiny to start with.
It's like foil in that what you are looking at can change dramatically very quickly. If you take an ink drop and put it water, the random motion of the water molecules diffuses the ink (spreads it out). This is called diffusion or Brownian movement.
It is like the foil because the crumpled foil has no set pattern.
Answer:
I would see it as a piece of glass since these ideas can be proven otherwise at any time.
Step-by-step explanation:
Throughout history, analogies have played an important role in scientific discoveries, not as proof, but as inspiration. Analogies have also played an important role in explaining those discoveries (Kaiser, 1989).

Which equation has a constant of proportionality equal to 7?
A. 4y = 28x
B. 7y = 28x
C. 28y = 4x
D. 28y = 7x
Answers
Reasoning: 4 x 7 = 28
good luck!
The solution is Option A.
The equation which has a constant of proportionality k = 7 is 4y = 28x
What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the equation be represented as A
Now , the value of A is
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
Now , the equation is
4y = 28x
On simplifying the equation , we get
Divide by 4 on both sides of the equation , we get
y = 28x/4
y = 7x
y = 7x is of the form y = kx where the value of k is 7
Therefore, the value of k is 7
Hence , the value of proportionality constant is 7
