20% if it will determine the pay of how much it is.
Step-by-step explanation:
you know by using the x and y coordinates of the point in the equations and see, if both equations are still true.
if yes, it was a solution, and if just only one is false, then it was not a solution.
(3, -2) in
y + 4x = 10
5x - y = 13
so,
-2 + 4×3 = 10
-2 + 12 = 10
10 = 10 true
5×3 - (-2) = 13
15 + 2 = 13
17 = 13 false
so, it was NOT a solution.
Answer:
C
Step-by-step explanation:
Angle CAD and angle BAD are congruent.
10x - 7 = 3x+ 7
10x - 3x = 7 + 7
7x = 14
(7x)/7 = 14/7
x = 2
Plug in x as 2.
10(2) - 7
20 - 7
= 13
Answer:
The length of each side is 31.5m, 26.5m, 7m
Step-by-step explanation:
Let the length of the first side of the triangle be x meters.
Then, the second side is x-5 meters.
The third side is given as 7 meters.
The perimeter is 65 meters
This gives us the equation:




The length of each side is 31.5m, 26.5m, 7m
