6 + 17/20

Make 6 have a common denominator with 17/20 before you can add them together.

Multiply 6/1 (which is the same as 6) by 20/20.

6/1 * 20/20 = 120/20

Add 120/20 and 17/20 together; add the numerators but keep the same denominators.

120/20 + 17/20 = 137/20

Answer:

Improper fraction: 137/20
Mixed number: 6 17/20
Decimal: 6.85

What is the value of tanØ

mr_godi [17]

Answer:

tan ∅ = 24 / 7

Step-by-step explanation:

cos ∅ = 7 / 25

sin^2 ∅ + cos^2 ∅ = 1

sin^2 ∅ + (7 / 25)^2 = 1

sin^2 ∅ = 1 - 49 / 625

sin^2 ∅ = 625 - 49 / 625

sin^2 ∅ = 576 / 625

sin ∅ = root 576 / 625

sin ∅ = 24 / 25

tan ∅ = sin ∅ / cos ∅

tan ∅ = 24/25 / 7/25

Therefore, tan ∅ = 24 / 7

OPTION 4. 24 / 7

The table shows the outputs, y, for different inputs, x: Input (x) 6 12 15 25 Output (y) 14 15 15 16 Part A: Do the data in this

cluponka [151]

Answer:

Part A: No it is not a function

Part B: The equation

Part C: x = 3

Step-by-step explanation:

Part A - The table:

Input (x) Output (y)

6 14

12 15

15 15

25 16

This is a function because it has no repeating inputs values which have alternate outputs. Each input is assigned exactly one output.

Part B - The relation y = 7x - 15 has the value y = 27 when x = 6. You can find it by substituting into the equation.

y = 7(6) -15

y = 42 - 15

y = 27

The value of the relation in the table when x = 6 is y = 14. The equation has the greater value.

Part C: To find when y = 6, set it equal to 6 and solve for x.

6 = 7x - 15

21 = 7x

3 = x

Solve the equation 9x = 7(x + 2). <br> A) -7 <br> B) -1 <br> C) 1 <br> D) 7

HACTEHA [7]

Answer:

The solution of the equation 9x=7(x+2) is:

Option D) 7

Step-by-step explanation:

9x=7(x+2)

Eliminating the parentheses applying distributive property:

9x=7(x)+7(2)

Multiplying:

9x=7x+14

Grouping the x's on the left side of the equation: Subtracting 7x both sides of the equation:

9x-7x=7x+14-7x

Subtracting:

2x=14

Solving for x: Dividing both sides of the equation by 2:

2x/2=14/2

Dividing:

x=7

Solution: x=7 (option D)
