 N0. There are not enough teacher signatures.

Step-by-step explanation:

Total signatures needed: x 1200 = 150

Total signatures received: 150

********************************************************************

Teacher signatures needed: x 150 = 6

Teacher signatures received: x 150 = 4

Side note: If there are student signatures then there are teacher signatures, because the student plus teacher signatures must equal 100%

the answer is this cannot be presented

Step-by-step explanation:

We need signatures (1/8) of 1200 = 150 (students/teacher)

But (1/25) of 150 = 6 (must be from teachers)

So 144 students+ 6 teachers signature is all we need!

* Currently we have (73/75) of 150 = 146 (signatures from students)

the rest is (2/75) of 150 = 4 (signatures from teachers)

> we dont have enough (1/25) signatures of the teachers

if x decreases by 4 then y increases by 10

step-by-step explanation:

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
