C. Josh worked longer than Vicki worked on her garden.
D. Vicki worked longer on her garden than Stacey & Josh combined.

Answers

so basically since josh worked a fraction (that's less than 1) of staceys time then therefor stacy's tme is more than josh
josh<stacy
vicki worked a fraction(that's greater than 1) of stacey's time. since it is greater than 1, it makes it more so like 2 times 2 and 1/2=2+1=3 which is greater so
viki worked more than stacy therefor

josh<stacy<vicki
so
A is correct (Stacey>josh)
B is correct (Stacey<Viki)
C is false
D we have to solve by doing
4 and 3/4 convert to fraction improper
4 and 3/4=19/4
19/4 times 2/3=josh=38/12=19/6
viki worked 1 and 3/8 of stacey
19/4 times 1 and 3/8=19/4+57/32=209/32=7.9
josh+stacey=19/4+19/6=95/12=6.5
7.9>6.5 so
D is true

so the answers that are true are
A,B,D

2a is true and 2b is also true and 2c is false 2d is true

- 8x-10y=20
-8x - 6y=-4

Answers

Answer:

x=5 y =-6

Step-by-step explanation:

- 8x-10y=20

-8x - 6y=-4

Multiply the first equation by -1

8x +10y=-20

Add this to the second equation

8x +10y=-20

-8x - 6y=-4

------------------

4y = -24

Divide each side by 4

4y/4 = -24/4

y = -6

Now we need to solve for x

8x +10(-6) = -20

8x -60 = -20

Add 60 to each side

8x -60+60 = -20+60

8x = 40

Divide each side by 8

8x/8 = 40/8

x =5
