Answer:
x=8.4
Step-by-step explanation:
4x +8y=40
replace y as 0.8
4x+8*0.8=40
4x+6.4=40
subtract 6.4 from both sides
4x=33.6
divide by 4
x=8.4
Answer:
x = 9
Step-by-step explanation:
60 + 6x + 16 = 13x + 13
6x - 13x = 13 - 16 - 60
- 7x = - 63
- x = - 63/7
- x = - 9
x = 9
Answer:
1/2x plus -2
Step-by-step explanation:
<h3>No it does not form a triangle!~</h3>
Let's prove it by pythogoras theorem,
- Hypotenuse = 23
- Base = 7
- Perpendicular = 16




<h3>Hence (Proved) </h3>
