2xy-yz=8 solve for z

Answers

Answer 1
The answer is: z = -8/y + 2x
Answer 2

The solution of the equation in terms of z will be; z = 2x - 8/y

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given the equation as;

2xy-yz=8

Now we have to solve for z;

2xy-yz=8

-yz = 8 - 2xy

Then divide by y on both sides;

z = 2xy/y - 8 / y

z = 2x - 8/y

Answers

Answer:

$3.66

Step-by-step explanation:

5.00-2.00 = 3.00

0.95-0.29 = 0.66

3.00 + 0.66 = $3.66 which is the answer

Ok,so:

We don’t need the $ sign now.

So.

1. 5.95 -2.29 which is 3.66!

5 - 2 is 3, and 0.95 - 0.29 is 0.66.

So now add :3 + 0.66 is 3.66

So $3.66!

x =

Answers

Answer:

x = 9

Step-by-step explanation:

Step 1: Subtract 4x from both sides.

[tex]7x - 4x = 4x + 27 - 4x[/tex] [tex]3x = 27[/tex]

Step 2: Divide both sides by 3.

[tex]\frac{3x}{3} =\frac{27}{3}[/tex] [tex]x = 9[/tex]

Step 3: Check if solution is correct.

[tex]7(9) = 4(9) + 27[/tex] [tex]63 = 36 + 27[/tex] [tex]63 = 63[/tex]

Therefore, x = 9.

7x = 4x +27
3x = 27
x = 9

Answers

The equation in point-slope form to represent the time y it took to download x songs is; (y - 35) = 7(x - 5)

Since it took 35 seconds for 5 songs to download

and it took 42 seconds for 6 songs to download

In essence, we can represent the information as;

(5, 35) and (6,42)

To find the slope of the equation; we have;

Slope, m = (42-35)/(6-5)

m = 7

6, 12, 18, 24, 30, 36, 42, 48, 54 (the bolded numbers go in the box)

Step-by-step explanation:

1. To find the multiples of 6 between 6 and 54, we have to multiply 6 by numbers from 1 to 9.

6 × 1 = 66 × 2 = 126 × 3 = 186 × 4 = 246 × 5 = 30 6 × 6 = 36 6 × 7 = 426 × 8 = 48 6 × 9 = 54

Therefore, the multiples of 6 between 6 and 54 are 6, 12, 18, 24, 30, 36, 42, 48, 54. (again, the bolded numbers go in the boxes)

<1 and <2 are complementary. Solve for the measure of <1.

<1 = 12x + 4
<2 = 9x + 2

A. 52
B. 4
C. 38
D. 8.3

Answers

Answer:

A) 52

Step-by-step explanation:

If < 1 and < 2 are complementary angles, then it means that the sum of their measures add up to 90°.

< 1 + < 2 = 90°

12x + 4 + 9x + 2 = 90°

21x + 6 = 90°

21x + 6 - 6 = 90° - 6

21x = 84°

21x/21 = 84°/21

x = 4

Substitute the value of x = 4 into < 1 and < 2:

m < 1: 12x + 4 = 12(4) + 4 = 52°

m < 2: 9x + 2 = 9(4) + 2 = 38°

Therefore, the correct answer is A) m < 1 = 52°.
