4x+6+3=17
4x+9(add the 6 and 3)=17
4x=8(subtract 9 from each side 4x+9-9=17-9)
x=2(divide each side by 4, 4x/4=8/4)
2 is the final answer.
You can check your work...
4(2)+6+3=17
8+6+3=17
14+3=17
17=17
So this is correct!!! Hope this helps you.
Answer:
Step-by-step explanation:
Number of shells she had in the begining = 40
Number of shells collected in the morning and at noon = 6 + 3 = 9
Now the number of shell at the end = 40 + 9 = 49
Icreased shells = 49 - 40 = 90
If we're talking about a box with dimensions 10 ft, 19 ft and 20 ft, it's probable that the instructions say to calculate the volume. That would be
V = (10 ft)(19 ft)(20 ft) = 3800 cubic feet.
the answer is 77 degrees celcius
