Answer:

A.The value of both expressions when t=3 is 33.

D.The value of both expressions when t=6 is 51.

E.The two expressions are equivalent.

Step-by-step explanation:

We are given two expressions.

3(2t + 5)

6t + 15

Now let's find the value of these two expressions when t =3 and t = 6

When t =3, the value of the expressions:

3(2*3 + 5) = 3(6 + 5) = 3(11) = 33

6*3 + 15 = 18 + 15 = 33

So the value of both the expressions is 33 when t = 33.

When t = 6, the value of the expressions:

3(2*6 + 5) = 3(12 + 5) = 3(17) = 51

6*6 + 15 = 36 + 15 = 51

The value of both the expressions is 51 when t = 51.

So the following statements are true:

A.The value of both expressions when t=3 is 33.

D.The value of both expressions when t=6 is 51.

E.The two expressions are equivalent.

Answer:

I would do the math

Answer:

1) 23^a+b

2) 5^5

3) 11^x-y

4) 2^10

Step-by-step explanation:

if they have the same base numbers then they are pretty easy to combine. multiplication means you add the exponents, and division means you subtract the exponents. for number 2, you would make them the same base by making 25 -> 5^2 and then just add the exponents.

hello :

put x=0 and y= -3 in this system !

Y = 3/4x - 3

3x - 4y = 12

- 3 = 3/4(0) - 3  means : -3 = -3 ......true

3(0) - 4(-3) = 12  means : 12= 12 ......true

Step-by-step explanation:

11+13<25

y < -12

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

−2y − 8 > 16

Step 2: Add 8 to both sides.

−2y − 8 + 8 > 16 + 8

−2y > 24

Step 3: Divide both sides by -2.

−2y/−2 > 24/−2

y < −12

Answer:

y < −12

Step-by-step explanation:

                                                     −2(y + 4) > 16      

                                                               ↓

                                                      −2y − 8 > 16

                                                               ↓

                                                          y < −12

Answer:

its a. 475.26

Step-by-step explanation:

445/ 100= 4.45

4.45×3.4=15.13

15.13+445=460.13

460.13+15.13= 475.26

Step-by-step explanation:

1. Angle 5 = 120 degree

Angle 5 = Angle 6 ( alternate exterior angles are equal )

Therfore, Angle 6 = 120 degree

Angle 6 = Angle 4 ( Vertically opposite angles are equal )

Therfore, Angle 4 = 120 degree

Angle 4 = 5x

120 = 5x

120/5 = x

40 = x

Therefore x = 40 degree.

2. Angle 1 = 100 degree

Angle 1 = Angle 7 ( vertically opposite angles are equal )

Therefore, Angle 7 = 100 degree

Angle 7 = 10x

100 = 10x

100/10 = x

10 = x

Therefore x = 10 degree

Answer:

28.71 points

Step-by-step explanation:

(27.29 + 28 + x) / 3 = 28

(27.29 + 28 + x) = 84

28 + x = 56.71

x = 28.71

The number of points he needs to score in his next game so that his average (mean) is 28 points per game will be 28.

The mean is the average of a data set. Mean gives us an idea of that how much amount of overall data have.

Mean = sum of data / Number of data

As per the given,

Manuel has scored 27,29 and 28 points in his three basketball games so far.

Suppose his score in the fourth game is x.

Mean = (27 + 29 + 28 + x)/4 = 28

(84 + x)/4 = 28

84 + x = 112

x = 28

Hence "The number of points he needs to score in his next game so that his average (mean) is 28 points per game will be 28".

Explanation:

The quadrilateral will be a parallelogram if the diagonals bisect each other. That is, their midpoints are the same point. We don't actually need to calculate the midpoint. Rather, we can calculate the point that has double the coordinate values.

If (A+C) = (B+D), the quadrilateral is a parallelogram.

  A +C = B +D

  (-2, 8) +(5, 1) = (2, 7) +(1, 2)

  (-2+5, 8+1) = (2+1, 7+2)

  (3, 9) = (3, 9) . . . . . the figure is a parallelogram

_____

Of course, the midpoint of the diagonals is (3/2, 9/2).
