Answer:
15, inches, 7, inches
Step-by-step explanation:
44=2(8+l)+2l
44=16+4l
28=4l
7=l
l=7
w=8+7
w=15
Answer:
y = 3
x = -4
Step-by-step explanation:
Hopefully the first equation is x + 3y = 5
x = 5 - 3y
Plug in:
-2(5 - 3y) + 2y = 14
-10 + 6y + 2y = 14
8y = 24
y = 3
x = -4
In order to find x-axis interception coordinates you need to set other two variables (y and z) to zero and solve the remaining equation.
So the following simple equations need to be solved:
2x = 40
5y = 40
-4z = 40
It intercepts x-axis at coordinates (20;0;0), y-axis at (0;8;0) and z-axis at (0;0;-10).
Answer:
x=0.3
Step-by-step explanation:
4x-4/5=2/5
4x=4/5+2/5=6/5
x=6/20=3/10=0.3
Answer:
x = -5
Step-by-step explanation:
Divide each term by 4 and simplify.
Move all terms not containing X to the right side of the equation.
Divide each term by 3 and simplify.
