A is the answer for number 6
3x-y=6
y=x-4
solve by substitution
3x-x+4=6
2x=2
x=1
Now that you know x, but in in the equation to find y (either equation will work)
y= 1-4
y= -3
now that you have both answers, let's check them.
3(-1) - (-3) =6
yes, it works....
Hopefully this makes sense!
Hey, me again! So, I'll be giving you the totals for EACH group.
For the first group, multiply 1/8 by 3 to get the answer;
3/8 lbs
Do the same for this group (and all of the others) so that the answers are:
Group 2 - 3/4lbs
Group 3 - 2/2 = 1lb
Group 4 - 5/8lb
Group 5 - 7/8
Answer:
30420ft
Step-by-step explanation:
We have to break the shape into two. So..
13 times 26=338
now the top..23-13=10
10 times 9 = 90
338 times 90 = 30420 ft
Y2-y1/x2-x1
(1,14) & (3,4)
y2= 4
y1=14
x2=3
x1=1
So....
(4-14)/(3-1) = -10/2 = -5
The answer should be negative instead of positive, she probably subtracted 4 from 14 instead.
