If 3 is added to a certain number, the results is 15 less than three times the number. Find the number

Mathematics

Answer:

number = 9

Step-by-step explanation:

number = x

3 is added to a number = (x+3) result

3 times the number = 3x

15 less than three times the number = 3x-15

the results is 15 less than three times the number

x+3 = 3x -15

3x-x= 3+15

2x = 18

x=9

Answer:

Sin Z = 8/17

Tan G = 15/8

Cos Z = 15/17

Sin M = 1

Step-by-step explanation:

Sin is equivalent to Opposite over Hypotenuse. For Z, the opposite would be 40. 85 is always the hypotenuse in this problem.

Sin Z = 40/85, simplified it is 8/17

Tan is opposite over adjacent. In this case, the opposite is 75. The adjacent is 40.

Tan G = 75/40, simplified it is 15/8

Cos is adjacent over hypotenuse. In this one, the adjacent is 75. The hypotenuse is 85.

Cos Z = 75/85, simplified it is 15/17.

In Reference to what I said above Sin, I will use the same thing.

Sin M = 1

85/85

What value of b will cause the system to have an infinite
m_a_m_a [10]

Answer:

b=6

Step-by-step explanation:

<u><em>The correct question is</em></u>

What value of b will cause the system to have an infinite number of solutions?

y = 6x – b

–3x + 1/2y = –3

we have

y=6x-b ----->equation A

-3x+\frac{1}{2}y=-3 -----> equation B

we know that

If the system has infinite number of solutions then, the equation A must be equal to the equation B

so

isolate variable y in the equation B

-3x+\frac{1}{2}y=-3

Multiply by 2 both sides

-6x+y=-6

y=6x-6 -------> new equation B

To find out the value of b, equate equation A and equation B

6x-b=6x-6

b=6
