7. What's the sum of 2/5 and 2/4?
NISA [10]

Step-by-step explanation:

2/5+2/4 (find common denominator)

The common denominator is 20

2/5 is 8/20 (multiply by 4)

2/4 is 10/20 (multiply by 5)

8/20+10/20 is 18/20

If you simplify 18/20 this would by 9/10 if you divide by 2

so the total is 18/20 or 9/10 simplified

Hope this helps!!!!

Have a nice day :)

Solve the system by substitution. -4.5-2y=-12.5 , 3.35x-y=-0.75
goldenfox [79]
First, we solve for y in the first equation:
-2y = -12.5 +4.5
-2y=-8
y= \frac{8}{2}
y=4
Then, we substitute the y value in the other equation and solve for x:
3.35x-(4)=-0.75
3.35x=-0.75+4
3.35x=3.25
x= \frac{3.25}{3.35}
x= \frac{65}{67}
