Answer:
Step-by-step explanation:
For this you just find the average of the 3 numbers
To find the average you add all of the numbers together and divide by the number of numbers
4+1+9
=14
14/3
=4 and 2/3
Since you can't have 2/3 of a cow, round up
5 cows (on average)
Answer:
Step-by-step explanation:
If R, A, and P all share 108 pounds in the ratio of 2 to 3 to 1, then
2x + 3x + 1x = 108 and
6x = 108 so
x = 18.
R holds the ratio of 2x, so he gets 2(18) which is 36;
A holds the ratio of 3x, so he gets 3(18) which is 54;
P holds the ratio of 1x, so he gets 1(18) which is 18.
36 + 54 + 18 better equal 108...and it does!
Number 1 = 17
number 2 = 72
number 3 = 24
work:
the three numbers are symbolized as x, y, and z
x + y + z = 113
number 2 (y) is 3 times the third number (z) so
y = 3z
so x + 3z + z = 113
the first number (x) is 7 less than than the third number (z) so
x = z - 7
so z -7 + 3z + z = 113
5z - 7 = 113
5z = 120
z = 24
x = 17
y = 72
Hope this helped :)
Hello from MrBillDoesMath!
Answer:
75
Discussion:
A plane triangle has 180 degrees. Using this in the diagram gives
x + 81 + angle BAC = 180 (***)
(The diagram is a bit fuzzy but I think the above numbers are accurate)
The diagram also shows that (156 + angle BAC )= 180 as a straight line has 180 degrees. So
angle BAC = 180 - 156 = 24
Substituting this in (***) above gives
x + 81 + 24 = 180 =>
x + 105 = 180 => (as 81 + 24 = 105)
x = 180 107 = 75
Check: Does
x + 81 + angle BAC = 180 ?
75 + 81 + 24 = 180. Yes
Thank you,
MrB
