kristen is building a pattern using triangles, the table shows the number of triangles in the first 4 terms of that pattern. which formula describes the number of triangles in the nth term of the pattern.

A. n=t+2
B.n=t+3
C. n=2t-1
D. n=2t + 3​

Answer:

The slope of the lines is 1/3

Step-by-step explanation:

Since I can't graph it, I can make a table

x         y

8        5

2        3

From 5 to 3, you subtract 2 (this is for the y section)

From 8 to 2, you subtract 6 (this is for the x section)

Now all you have to do is divide y by x....

y/x = 2/6 = 1/3 (when simplified)

Hope this helped!

Step-by-step explanation:

x=50 is the solution to the equation -0.20(x– 20) = 44-x. So, option C is correct.

Solution to an equation means that value of the variable for which the equation is satisfied.

Given the following equation:

-0.20(x– 20) = 44-x

A

To check x=-90 is the solution:

Put x=-90 in the given equation

LHS=-0.20(x– 20)

=-0.20(-90-20)

=-0.2(-110)

LHS=22

RHS= 44-x

=44-(-90)

RHS=134

LHS≠RHS

Thus, x=-90 is not the solution.

B

To check x=-50 is the solution:

Put x=-50 in the given equation

LHS=-0.20(x– 20)

=-0.20(-50-20)

=-0.2(-70)

LHS=14

RHS= 44-x

=44-(-50)

RHS=94

LHS≠RHS

Thus, x=-50 is not the solution.

C

To check x=50 is the solution:

Put x=50 in the given equuation

LHS=-0.20(x– 20)

=-0.20(50-20)

=-0.2(30)

LHS=-6

RHS= 44-x

=44-(50)

RHS=-6

LHS=RHS

Thus, x=50 is not the solution.

D

To check x=90 is the solution:

Put x=90 in the given equation

LHS=-0.20(x– 20)

=-0.20(90-20)

=-0.2(70)

LHS=14

RHS= 44-x

=44-(90)

RHS=-54

LHS≠RHS

Thus, x=-90 is not the solution.

Thus x=50 is the solution to the given equation. So, option C is correct.

Answer: -3

mark me brainiest very easy  answer

Answer:

Rewrite the first equation as x = 36 – 3y.

Step-by-step explanation:

x + 3y = 36 (1)

4x + 5y = 9 (2)

Using substitution method

From (1)

x = 36 - 3y

Substitute x = 36 - 3y into (2)

4x + 5y = 9

4(36 - 3y) + 5y = 9

144 - 12y + 5y = 9

- 12y + 5y = 9 - 144

-7y = -135

y = -135 / -7

y = 19.3

There is an error with the second equation, 4x + 5y can not be equal to 9

Nevertheless, the first step when solving by substitution is:

Rewrite the first equation as

x = 36 – 3y.

Answer:

BA = 3

AC = 3

BC = 2

x = 4

Step-by-step explanation:

Find x

BA and CA are equal            Given

2x - 5 = 3x - 9

Subtract 2x from both sides

- 5 = 3x - 2x - 9

- 5 = x - 9            

Add 9 to both sides.

- 5 + 9 = x - 9 + 9

4 = x

=========================

BA = 2x - 5

BA = 2*4 - 5

BA = 3

AC = 3x - 9

AC = 3*4 - 9

AC = 12 - 9

AC = 3

BC = x - 2

BC = 4 - 2

BC = 2

Answer:

Step-by-step explanation:

We need to find 5 sides of the cube and 4 sides of the pyramid.

For the cube, each side's area is [tex]s^{2}[/tex] with s being the side length. Since there are 5 sides, it would be 5 x  [tex]s^{2}[/tex]. s=15, so it would be 5 x 15 x 15, which is 75 x 15 which simplifies into 1125.

For the pyramid, we need to find the area of all 4 triangles. They are all the same triangle, each with a base of 15 and a height of 9.  So one triangle's area is 9 x 15/2 = 67.5 --> Since there are 4 triangles, the area of all of them would be 67.5 x 4 which is 270.

1125 + 270 = 1395 cubic ft. (or [tex]ft^{3}[/tex])

Answer:

The decimal form of [tex]\frac{1}{15} = 0.0666... = 0.0\overline{666}[/tex].

Step-by-step explanation:

We proceed to find the decimal form of [tex]\frac{1}{15}[/tex], whose description is found below:

1) Multiplying the numerator by 100 and dividing it by 15:

Partial result: 0.06, Remainder: 10

2) Multiplying the remainder by the 10 and dividing it by 15:

Partial result: 0.066, Remainder: 10

3) Multiplying the remainder by the 10 and dividing it by 15:

Partial result: 0.0666, Remainder: 10

Since the decimal number is a infinite and periodical, we conclude that decimal form of [tex]\frac{1}{15} = 0.0666... = 0.0\overline{666}[/tex].

Answer: See the diagram below

Specifically, refer to figure 4.

==========================================================

The set U is the universal set. It represents every teacher. Let's draw this as a rectangle. Divide the rectangle so that one portion represents female teachers, and the other represents male teachers. I'll use a vertical line to divide the universal set.

Now draw a circle such that one portion of the circle is in the "male teacher" region and the other portion of the circle is in the "female teacher" region. Lastly, shade the region inside the circle that is also in the male teacher region. The diagram below shows the step by step process.

Figure 1 is the rectangle representing the universal set, which in this case is the set of all teachers.

Figure 2 splits up set U into female teachers on the left and male teachers on the right.

Figure 3 adds a circle, set M, to represent all math teachers. This circle spans the male and female teacher regions, since we can have either male or female math teachers.

Figure 4 adds labels A,B,C,D such that

There are no gaps or overlaps between any of the A,B,C,D regions. We consider these regions to be mutually exclusive. If a person is in region B for instance, then they cannot be in any other region. This is assuming no person teaches more than one subject. Note how regions A,B,C,D completely fill the set U, and do so without any gaps or overlaps. So we can say that set U is partitioned into those four regions.

Answer:

13, 14, 15

Step-by-step explanation:

Let x = age of one of the siblings

Since the age of the siblings are consecutive integers, the age of the next sibling would be x + 1 and the age of the third sibling would be x + 2

x +( x +1) + (x +2) = 42

3x + 3 = 42

collect like terms and solve for x

x = 13

The age of the first sibling is 13

The age of the second sibling is x + 1 = 13 + 1 = 14

The age of the third sibling is x + 2 = 13 + 2 = 15
