5+x=-9
Use the subtractive property of equality to isolate x.
5+x=-9
-5 -5
x=-14
The value that satisfies x is -14. You can check your work by substituting x as -14 and checking if the equation is satisfied.
5+x=-9
x=-14
5+(-14)=-9
5-14=-9
-9=-9
the answer is correct. Succinctly, x=-14.

Step-by-step explanation:
Find the volume of the whole box 1st.
Volume = 15×28×20 = 8400 centimeters^3
Next find the volume of the disc 2and
Volume = 19.3×14.2×1.5 = 411.09 centimeters^3
Since we know the volume of both we now have to multiply the number of disc by its volume.
6988.53 = 411.09(17)
8400-6988.53= 1411.47
1411.47/ 411.09 = 3.4 MEANING 3 more fit
Answer:
x = 2
Step-by-step explanation:
A parallelogram is a figure with four sides in total, and two parallel opposite sides.
This means that the opposite sides are equal in length.
For the parallelogram ABCD in this problem, we are told that the length of two opposite sides are:
and
The two sides must be equal in order for ABCD to be a parallelogram, so we can write:
And now we solve for x: first, we add +5 on both sides,
Then we subtract 15x on both sides:
Finally, we divide both sides by 5:
