Answer: x=94
Step-by-step explanation:
The anwser
Let the number of professors be x.
Hence, number of students = 16x
Professors + students = 17000
x + 16x = 17000
17x = 17000
x = 1000
Thus,
Number of professors = 1000
Number of students = 1000 * 16 = 16000
Answer:
Baseball gloves = 17 gloves || Bats = 11 bats
Step-by-step explanation:
Let baseball gloves be x and bat be y
<em>Possible Equations:</em>
x + y = 28
29x + 14y = 647
-----------------------------------
make x the subject:
x + y = 28
x = 28 - y .........equation 1
29x + 14y = 647
x = (647 - 14y)/29 .........equation 2
----------------------------------------------------------------
<u>Solve them simultaneously:</u>
28 - y = (647 - 14y)/29
29(28 - y) = 647 - 14y
812 - 29y = 647 - 14y
-14y + 29y = 812 - 647
15y = 165
y = 11
So the number of bats he sold is 11 bats.
number of gloves he sold: x = 28 - y
: x = 28 - 11
: x = 17
So number of baseball gloves he sold is 17 baseball gloves.
