Answer:
3) x = 15; 95 and 85 4) x = 12; 98 for both angles
Step-by-step explanation:
2x + 65 + 3x + 40 = 180 Set the equations equal to 180
5x + 105 = 180 Combine like terms
- 105 - 105 Subtract 105 from both sides
5x = 75 Divide both sides by 5
x = 15
Plug 15 into both equations
2(15) + 65 = 95
3(15) + 40 = 85
4) 5x + 38 = 9x - 10 Set the equations equal to each other
- 5x - 5x Subtract 5x from both sides
38 = 4x - 10
+ 10 + 10 Add 10 to both sides
48 = 4x Divide both sides by 4
12 = x
Plug 12 into both equations
5(12) + 38 = 98
9(12) - 10 = 98
62 + x = 82
Subtract both sides by 62.
x = 20.
Pretty sure it´s 12.25
61.25 /5=12.5
you can check this by doing 12.5 x 5 ; 15 or 30 and you´ll get the same product in monthly earned
Answer is 3.
3,6
3,6,9,12,15,18,21,24,27
3,6,9,12,15,18,21,24,27,30
Just count the amount of each letter and write it as a exponent = 3x²y³
