Answer:

67.5

Step-by-step explanation:

I've learned this multiple ways but in my opinion this is the easiest. Just times everything together so, 40 x 2.5 x 1.2 which equals 135 and then divide 135 by 2 which equals your answer of 67.5 which is rounded to the nearestt tenth already.

Find the slope and the y-intercept of the equation y − 3(x − 1) = 0.
djyliett [7]
Y-(3x-1)=0
y-3x+1=0
y=3x-1
The equation is in the form y=mx+q where m is the slope and q is the y-intercept.
Then the slope of that line is 3 and y-intercept is -1

Can anyone help me with this math question
Lynna [10]

Answer:

89 seats are not being used

Step-by-step explanation:

You subtract the seats being used by teachers

342 - 75 =267

Change 2/3 into a percentage = 66.6%

Find 66.6% of 267= 177.8 (I rounded up to 178)

Then subtract 177.8/178 from 267 to find the amount of seats not being used.

The amount of seats not being used would come down to 89 seats.

I hope this helps!
