Step-by-step explanation:
4x + 5 = 6x – 7
solve for x
Answer:
x = 6
Step-by-step explanation:
4x + 5 = 6x - 7 subtract 4x from both sides
5 = 2x - 7 now add 7 to both sides
12 = 2x finally divide both sides by 2
x = 6

The sum of the lengths of any two sides is greater than the third side, then the given sides will form a triangle.
Apply the theorem statement for the given numbers 10, 7 and 13. Do these numbers form a triangle? Explain
Answer:
Yes, These numbers 10, 7, and 13 can form a triangle
Step-by-step explanation:
The sum of any two sides of a triangle is greater than the third sideLet us use this theorem to solve the question
∵ The numbers are 10, 7, 13
∵ 10 + 7 = 17
∵ 17 > 13
∴ The sum of 10 and 7 is greater than the 3rd number 13
∵ 10 + 13 = 23
∵ 23 > 7
∴ The sum of 10 and 13 is greater than the 3rd number 7
∵ 7 + 13 = 20
∵ 20 > 10
∴ The sum of 7 and 13 is greater than the 3rd number 10
∵ The sum of every two numbers is greater than the 3rd number
→ By using the theorem above
∴ The numbers 10, 7, and 13 can form a triangle

All angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Set up equation
(x + 1)° + (10x - 7)° + (8x - 4)° = 180°
Step 2: Solve for x

can someone please help?
Answer:
The answer is in the explaination
Step-by-step explanation:
A + B = 180 degrees
14x - 72 = 180
14x = 108
x = 8
A = 5 times 8 plus 20
A = 60
Answer:
110 degrees.
Step-by-step explanation:
Angle A + Angle B = 180 degrees.
Therefore, 5x+20+9x-92=180
When you solve you get 14x=252 or x=18
When you plug that into A you get 5(18)+20=110
Therefore, A=110 degrees
