we need to first find the answer to the equation.

2x+6=22

6-6=0

Answer: 8

Step-by-step explanation: 2x + 6 = 22

To get x

Subtract 6 from both sides to make 2x the subject

2x + 6 - 6 = 22 - 6

2x = 16

Divide both sides by 2 to get x

2x/2 = 16/2

x = 8

Answer:

A = 52°, a = 149.2, c = 174.3

Step-by-step explanation:

Technology is useful for this. Many graphing calculators can solve triangles for you. The attachment shows a phone app that does this, too.

___

The Law of Sines can give you the value of c, so you can choose the correct answer from those offered.

c = sin(C)·b/sin(B) = sin(113°)·49/sin(15°) ≈ 174.271 ≈ 174.3 . . . . . third choice

The sum of a number times 10 and 17 is at most 27

guajiro [1.7K]

Answer:

The value of the number should be 1 (or less I think)

Step-by-step explanation:

At most means the highest value of the sum should be 27.

10x + 17 = 27

10x = 27 - 17

10x = 10

x = 10/10

x = 1

∴The value of the number should be 1
