Answer:
C
Step-by-step explanation:
The first term -2 is also -B; therefore A and B can be eliminated.
-1+3 is 2, and -4 is the only term used in the formula, so D is also eliminated
So for me, how I would do it is move the variables and numbers to one side. So we have the equation 3x-3=2/5x+7. So you would subtract 2/5x to the left side and add 3 to the right side. The equation will then turn out to be 3x-2/5x=7+3. Much more easier right? So just simplify both side, and you will get 13/5x=10. In order to isolate x, you have to divide 13/5 in both side, leaving x= 3 11/13 or 50/13. You can always plug the answer back in to double check :)
Answer:
D. rectangle with a width of 7 cm and a length of 8 cm
Step-by-step explanation:
If you multiply 7 and 8 you get 56, which is the least area in all of these figures.
8(x+18) is less than or equal to 19
2/4 ÷ 2/2 = 1/2
6/18 ÷ 6/6 = 1/3
4/20 ÷ 4/4 = 1/5
