Answer:
see below
Step-by-step explanation:
Since AB + BC = AC, x + 3x = 20 → 4x = 20 → x = 5.
AB = x = 5 and BC = 3x = 3 * 5 = 15.
Answer:
x = 9, y = 29 or (8,29)
Step-by-step explanation:
Set the equations equal to each other because they both equal y:
4x - 3 = 2x + 13
Combine like terms:
2x = 16
Divide by 2:
x = 8
Plug 8 into the x for both equations and see if the y is the same:
y = 4(8) - 3 = 32 - 3 = 29
y = 2(8) + 13 = 16 + 13 = 29
Answer:
Step-by-step explanation:
56 * .75 = 42
42+ 56 = 98
Answer is 98
Answer:
x=25
Step-by-step explanation:
The total angles of a triangle is 180°
So 180=36+61+(4x-17)
83=(4x-17)
100=4x
x=25
