x=1
Answer:
Salad(x)=6, smoothie(y)=4
Step-by-step explanation:
Salad=x
Smoothie=y
2x+4y=28 (1)
3x+5y=38 (2)
To eliminate the x- variable ,equ(1) is multiplied by -3 and equ(2) is multiplied by 2
-6x-12y=-84 (3)
6x+10y=76 (4)
Add equ (3) and (4)
-2y=-8
y=-8/-2
y=4
Substitute y=4 into equ(1)
2x+4y=28
2x+4(4)=28
2x+16=28
2x=28-16
2x=12
x=12/2
=6
x=6, y=4
Answer:
Step-by-step explanation:
#1 w=9 because:
2w+2(2w+3)=60
2*2w=4w and 2*3=6
2w+4w+6=60
Then: 2w+4w= 6w
6w+6=60
I just tried each answer I knew it had to be 8 or 9
So I tried 8 and it didnt work then I tried 9 and it did
6*9= 54+6=60
w=9
#2 I have a picture for this one I worked it out on paper. Check out the photo for the answer :)
Hope this helps!
