Answer:
the rounded answer is 14
Step-by-step explanation:
So volume of a cube=edge legnth cubed so take the cube root of 1000 and get 10
the side legnth is 10 feet
5 divided by 630 is about 0.007936
The substitution method means you replace the variable in one equation with the other equation, so your new equation is x+4x-8=10. Add 10 to both sides to get 5x=18. Divide both sides by 5 to get x=3.6. This is a weird equation, but then to get y, work backwords. 3.6 times 2=7.2. 7.2-4=3.2 y=3.2. Finally to finish checking solve the equation as normal. 3.6+6.4=10. I hope this helped! Please give brainliest!
Your final answer is x=3.6 y=3.2
