Question

A student computed the average of her 7 test scores by adding the scores together and dividing this total by the number of tests. The average was 87. On her next test, she scored a 79. What is her new test average?

Solution 1

After the new test, she now has taken 8 tests.

Set it up just like when finding the average:

(87+79)/8

Solve for the new test average

Set it up just like when finding the average:

(87+79)/8

Solve for the new test average

Question

Question

X + 5y = -2 2x + y = 5 The point of intersection of the lines has a y-coordinate of _____.
-1
1
or
3?

Solution 1

**Answer:**

**A. **

**Step-by-step explanation:**

We have been given a system of equations. We are asked to find y-coordinate of the point of intersection of the lines.

We will substitution method to solve our given problem. From equation (1), we will get:

Upon substituting this value in equation (2), we will get:

Now, let us solve for y.

**Therefore, the point of intersection of the lines has a y-coordinate of and option A is the correct choice.**

Solution 2

Y=1 , X=-1 I am very very positiveÂ about this answer.

Question

The area of a parallelogram is 15 centimeters squared. the length of the base is 5 centimeters. find the width. show all your work.

Solution 1

AÂ parallelogramÂ is a 4-sided shape formed by two pairs of parallel lines. Opposite sides are equal in length and opposite angles are equal in measure. To find theÂ area of a parallelogram, multiply the base by the height. We calculate as follows:

Area = b x w

15 = 5w

**w = 3 cm**

Area = b x w

15 = 5w

Question

Which of the following expressions represents "the sum of n and the sum of 8 and 6"?

Solution 1

The sum of 8 and 6 isÂ 8 + 6

The sum of n and the sum of 8 and 6 isÂ n + (8 + 6)

So the answer is B

The sum of n and the sum of 8 and 6 isÂ n + (8 + 6)

So the answer is B

Question

Solve each equation.
(x + 3)(x - 3) = 16 - 2x 2

Solution 1

(x+3)(x-3)=16-2x^2

x^2-3x+3x-9=16-2x^2

x^2+2x^2=16+9

3x^2=25

x^2=25/3

x= +/-âˆš25/3

x=+/- 5âˆš1/3

x^2-3x+3x-9=16-2x^2

x^2+2x^2=16+9

3x^2=25

x^2=25/3

x= +/-âˆš25/3

x=+/- 5âˆš1/3

Question

Consider this sequence: 1/32, 1/8, 1/2, 2, 8 I have the points I think? (1,1/32) (2,1/8) (3,1/2) (4,2) (5,8)
Graph the first five terms of the sequence.
Explain why the sequence is geometric.

Solution 1

In mathematics, aÂ geometric progression, also known as aÂ geometric sequence, is aÂ sequenceÂ of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio. Â The sequence has a common ration of: (1/8) / ( 1/32) = 4
