bearing in mind that a solution to a system of equations is where their graph intersect or meets, Check the picture below.
Answer:
80 inches
Step-by-step explanation:
12 x 7=34
23 x 2=46
34+46=80 inches
Find the soluiton
2x+2y=16
3x-y=4
x+y=8
<u>3x-y=4+</u>
4x=12
x=3
3(3)-y=4
9-y=4
y=5
(3,5)
test them to see if get true statment
obviously the first equatons of 1,2,4 work
1 doesn't work
2, works
4. doesn't work
2 is the same as the first except both euations are just doubled
answer is 2
This is the symmetric property, for you divide 9 to both sides to get x, instead of adding (addition property of equality)
So symmetric property should be your answer
Hope this helps
Answer:
It will take 3 hours. They will both have completed 11 rows.
Step-by-step explanation:
1 row of carrots per hour = frank
3 rows of tomatoes per hour = frank's mom
right now, this is how many they have completed
frank - 8 rows
mom - 2 rows
1st hour
f - 9
m - 5
2nd hour
f - 10
m - 8
3rd hour
f - 11
m - 11
