pls help I'm stuck, I would like an explanation if possible!
Answer:
60
Step-by-step explanation:
So they are showing you a chart in which the column y is determined by the column x, so you divide y/x in any of the rows so that you get the relation.
100/4=25 (which is the same for every row)
It works pretty much the same for the graph, but the relation is different.
Now instead of a chart you have to figure out the values of x and y by looking at the points that make up the line. For example we have a point that is in the coordinate (2, 60), and that represents that the x value is 2 and its correspondent y is 60. And to find the relation we do it as in the first step but now with 2 and 60.
60/2=30 (which is the same for every point)
Finally we just calculate the value of y both in the graph and the chart when x=12
So for the chart: 12*25= 300
And for the graph: 12*30= 360
The difference between those two is 60.
How do you convert 14x + 19y = 20 into slope intercept form?
Subtract 14x from both sides. Then divide both sides by 19
[tex]14x + 19y = 20\\\\19y = 20-14x\\\\19y = -14x+20\\\\y = \frac{-14x+20}{19}\\\\y = \frac{-14x}{19}+\frac{20}{19}\\\\y = -\frac{14}{19}x+\frac{20}{19}\\\\[/tex]
The equation is now in slope intercept form y = mx+b
m = -14/19 is the slope
b = 20/19 is the y intercept
Scenario:
A stack of n small cups has a height, h, in centimeters of h=1.5n+6.
A stack of n large cups has a height, h, in centimeters of h=1.5n+9.
Using G00gle Draw, or by hand, graph the equations for each cup on the same set of axes. Make sure to label the axes and decide on an appropriate scale.
For what number of cups will the two stacks have the same height?

You are ordering pizzas to share with friends. If you consider 3 slices (or 3/8 of a pizza) to be a single serving, how many servings will you get if you order 3 pizzas?
3 slices = 3/8 of a pizza 1 pizza = 8 slices 3 pizzas = 24 slices
Answer:
I belive you would get 8 servings in 3 pizzas. 24 divided by 3 is eight

k/7 + 3 − 2k = −3
Explain how to solve the problem. SHOW YOUR WORK!
Answer: 42/13
Step-by-step explanation: Multiply everything by 7 to eliminate the fraction:
k+ 21 - 14k = -21
Isolate the variable:
k - 14k = -21-21
13k= -42
divide the sides by -13.
42/13

Anna and Hal each create a triangle with measures 32°, 56°, and 92°. Anna’s fills a whole 8.5 in. by 11 in. sheet of paper, but Hal’s fills a small index card. Which of the following could represent their teacher’s comments on their work?
A.)Hal’s triangle is incorrect. Anna has created the only triangle whose angles measure 32°, 56°, and 92°.
B.)Anna’s triangle is incorrect. Hal has created the only triangle whose angles measure 32°, 56°, and 92°.
C.)Both triangles are incorrect. There are no triangles with angle measures 32°, 56°, and 92°. Two of the sides do not intersect.
D.)Both triangles are correct. There are many triangles with angle measures 32°, 56°, and 92° because the initial segment drawn can have any length.

A scale model of a boat is 6 inches long. The actual boat is 42 feet long. Which statement(s) are true??
Answer:
B. 1 in = 7 ft
Step-by-step explanation:
Since on the scale the boat was 6 inches and the actual boat was 42 feet, we need to divide to see how many feet correlate to the number on inches on the scale. So we do 42 / 6, which equals 7. This means that for every inch on the scale, it will be 7 feet in real life.
Which values for x make this inequality false?
Answer:
0, -11, -5, and 20
Step-by-step explanation:
The inequality can be read as x is less than -12.8 (or -12.8 is greater than x)
This means that we need to pick x values that are greater than -12.8 for the inequality to be false.
The values greater than -12.8 are:
0, -11, -5, and 20
A farmer planted corn in two different fields. He planted 500 seeds of regular corn in Field A and 500 seeds of experimental corn in Field B. At
harvest time, more ears of corn had grown in Field A than in Field B. The farmer concluded that more corn grew in Field A because of the type of corn planted.
Choose two other possible variables that could have caused more corn to grow in Field A.
A.

Choose two other possible variables that could have caused more corn to grow in Field A. The type of soil in the field
B. The cost per ear of the corn
C. The flavor of each type of corn
D. The amount of sunlight in each field
E. The amount of corn planted in each field
Answer:
its a and d obvioudly the price of the corn doesnt makethe corn be planted different
Step-by-step explanation:
so the soil causes the corn to grow in b if the soil was different then that would have caused it to grow less so A nd D

Does anyone also understand this?
Answer:
See explanation
Step-by-step explanation:
So, the angle for QRS is the interior angle of R. The exterior angle outside of angle R is for the equation you are going to use. Because angle R is on a straight line, the interior angle of R plus the exterior angle of R will equal 180 degrees. From there you should be able to calculate the rest of the angles, I believe you should be able to calculate y first.

Which values for x make this inequality false?
Answer:
-3, -0.01, -1/5
Step-by-step explanation:
The inequality can be read as x is greater than 0
-3, -0.01, and -1/5 are all values that are less than 0
So if these are the values of x, then the inequality would be false.

Urgent help pleaseeeeeee
Answer:
2x - 10 = 10 - 3x
Simplifying
2x + -10 = 10 + -3x
Reorder the terms:
-10 + 2x = 10 + -3x
Solving
-10 + 2x = 10 + -3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3x' to each side of the equation.
-10 + 2x + 3x = 10 + -3x + 3x
Combine like terms: 2x + 3x = 5x
-10 + 5x = 10 + -3x + 3x
Combine like terms: -3x + 3x = 0
-10 + 5x = 10 + 0
-10 + 5x = 10
Add '10' to each side of the equation.
-10 + 10 + 5x = 10 + 10
Combine like terms: -10 + 10 = 0
0 + 5x = 10 + 10
5x = 10 + 10
Combine like terms: 10 + 10 = 20
5x = 20
Divide each side by '5'.
x = 4
Simplifying
x = 4
