Answer:
D - 320
Step-by-step explanation:
You divide 48 by 15% and it equals 320 which is the starting value. To check your answer you take 15% out of 320 which gives you 48. Letter C is incorrect because 15% of 150 is 22.5. A and B are not correct because A is lower than the amount spent and there is no way that B would work because 15% of 55.20 is 8.28. Good luck with your math test!

Answer:
y=2x+6
I started with the simplist equation for the first set (0,6) of y=X+6 and then tested it out for the second set (1,8) which didn't work. I then ajusted it so it would work with the second set by doing y=2x+6. Lastly, I tested this equation with all of the points and it worked for them all.
Triangle BCD With Vertices B(4,4), C(8, 14), And P(12, 0); K = 1/4
Answer:
Hello, I am not sure if you mean a dilation by 1/4. If it is, this will be the answer:
B (1, 1)
C (2, 3.5)
D (3, 0)
Step-by-step explanation:
Just divide each number by 4. B (4, 4) = B (4/4, 4/4) = B (1, 1)
Continue to do this for each coordinate set given.

The vertices of triangle B'C'D' are:
B'(-1, -1/2)
C'(0, 2)
D'(1, -3/2)
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
To find the vertices of triangle B'C'D', which is a dilation of triangle BCD with center at the origin and a scale factor of 1/4,
We can follow these steps:
Find the coordinates of the centroid of triangle BCD.
The coordinates of the centroid G are:
[tex]x_G = (x_B + x_C + x_D) / 3 = (4 + 8 + 12) / 3 = 8[/tex]
[tex]y_G = (y_B + y_C + y_D) / 3 = (4 + 14 + 0) / 3 = 6[/tex]
Translate triangle BCD so that its centroid is at the origin.
We can do this by subtracting the coordinates of the centroid from the coordinates of each vertex:
B(4, 4) → [tex]B_1(4 - 8, 4 - 6) = B_1(-4, -2)[/tex]
C(8, 14) → [tex]C_1(8 - 8, 14 - 6) = C_1(0, 8)[/tex]
D(12, 0) → [tex]D_1(12 - 8, 0 - 6) = D_1(4, -6)[/tex]
Dilate the translated triangle [tex]B_1C_1D_1[/tex] by a scale factor of 1/4.
To do this, we can multiply the coordinates of each vertex by 1/4:
[tex]B_1[/tex](-4, -2) → B'(-4 x 1/4, -2 x 1/4) = B'(-1, -1/2)
[tex]C_1[/tex](0, 8) → C'(0 x 1/4, 8 x 1/4) = C'(0, 2)
[tex]D_1[/tex](4, -6) → D'(4 x 1/4, -6 x 1/4) = D'(1, -3/2)
Therefore,
The vertices of triangle B'C'D' are:
B'(-1, -1/2)
C'(0, 2)
D'(1, -3/2)

Nuha is 5 years older than her brother Cole. The sum of their ages is 37. How old is Nuha?
Cole age = x
Nuha age = x+5
x+x+5 =37
2x +5 =37
2x =32
x =16
Cole age = x = 16 yrs
Nuha age = x+5 =16+5 =21 yrs
So, she is 21!
Answer:
Nuha is 16
Step-by-step explanation:
x+x+5 =37
2x +5 =37
2x =32
x =16

Mrs.Rose received a 35% discount on her cell phone. The price of her cell phone came out to be $180. How much was the original price of her cell phone?
Answer:
The original price of the cell phone is $514.29
Step-by-step explanation:
The answer is $514.29 because the equation to find the answer is :
Let x = the original price of the cell phone
$180 = Price after discount
So, 180 = x * 35/100
Multiply by its reciprocal on both sides so
180 (100/35) = x
18000/35 = x
514.29 = x
So the original price of the cell phone is $514.29

4 times 13 is 52. Yes
3/4 times 13 is 9 3/4. No
10/10 times 13 is 13. Yes
The expressions greater or equal to 13 are B and D.
What is an expression?An expression in math is a statement having minimum of two numbers, or variables, or both and an operator connecting them.
Given are expressions we need to determine expressions having values equal to or greater than 13,
So,
5/6 and 3/4 are numbers less than 1 if we multiply any number with them it will decrease its value,
So, the expression 4 x 13 and 10/10 x 13 will be the expressions having values equal to or greater than 13.
Hence the expressions greater or equal to 13 are B and D.

The purpose of this task is for students to solve a mathematical problem using points in the coordinate plane. This task also helps lay the foundation for understanding operations on signed numbers without formally introducing those notions, which are not expected until 7th grade (see 7.NS.1). Students will not have the full machinery needed to find distances between two arbitrary points in the plane until they have studied the Pythagorean Theorem in 8th grade. However, it is straightforward for them to find horizontal and vertical distances, which mirrors how one might represent sums and differences of signed numbers on a number line. The solution for the first part shows how these questions can be represented using absolute values (as described in standard 6.NS.C.8), although students are unlikely to make this connection without being asked to do so. If students are asked to solve this problem on their own first, it could be used to launch a discussion of the relationship between the the absolute value of coordinates of points in the plane and their distance to the respective axes.
Please note that students will have to assume that the points have integer coordinates, which is reasonable but worth mentioning.
Solution
The distance between points B and C is 5 units, as indicated below.
We can determine the distance between points B and C by counting the units between the two points since they are on the same vertical line which happens to be a grid line.
We can also note that the coordinates for B are (3,2) and so it is |2| units above the x-axis. Similarly, the coordinates for C are (3,−3), so it is |-3| units below the x-axis. Thus, the distance between B and C is
|2|+|−3|=5
units.
The distance between points D and B is 7 units, as indicated below.
The distance between points D and E is 4 units, as indicated below.
Point C is the only one of points A,…E that is both 4 units away from (−1,−3) and 2 units away from (3,−1). There is another point that satisfies these two criteria (which is the other intersection point of the circle of radius 4 and circle of radius 2 shown below), but it does not have integer coordinates and is not one of the points identified in the task
A holiday meal cost $12.50 a person plus a delivery fee of 30$. Which equation is right?
1. y=30+12.50x
2. y= 12.50+30
3. 12.50x=30
4. y=12.50+30x
Answer:
1. y = 12.50x + 30
Step-by-step explanation:
A holiday meal cost $12.50 a person plus a delivery fee of 30$
Let x = number of people ordering a meal and y = total cost
It cost 12.50 per person so the cost regarding the number of people that orders food can be represented by 12.50x.
There is also a $30 delivery fee.
So the total cost would (y) = 12.50x + 30
The answer would be 1. 12.50 and 30 just swapped places.
