Answer:
x = 13.5
y = 7
(13.5,7)
what the solution means is that (13.5,7) would be the point at which the two lines, x+y=20.5 and x-y=6.5, would intersect
Step-by-step explanation:
x + y = 20.5
x - y = 6.5
if we add the two equations we get:
2x = 27
x = 13.5
y = 20.5 - 13.5
y = 7
solution as an ordered pair:
(13.5,7)
What the solution means is that (13.5,7) would be the point at which the two lines, x+y=20.5 and x-y=6.5, would intersect
Answer:
20
The range of a set of data is the highest number - the smallest number
32 - 12 = 20
The range is 20
Answer: 0.2
Step-by-step explanation:
subtract 9.38 - 3.5 = 5.88
distribute the 1.2.
7.56 - 8.4x = 5.88
subtract 5.88 - 7.56 = -1.68
-8.4x = -1.68
divide both sides by -8.4
answer = 0.2
Answer:
10m + 16
-5y + 15
Step-by-step explanation:
-3m + 16 - (-13m) =
= -3m + 16 + 13m
= 10m + 16
15y - 20y + 15 =
= -5y + 15
Answer:
Step-by-step explanation:
6*189=1134
9*90=810
1134+810= 1944 total
If I was to est, MYSELF, I'd say 6*200= 1200 and 9*100= 900 to make 2100 crayons.
