Step-by-step explanation:
2-5/4x=13
- (8x-5)/4x=13
- 8x-5=52x
- -5=52x-8x
- -5=44x
- x=-5/44
Ok so
250 left for student desks
250≥8n
n=number of desks
solve
divide both sides by 8
31.25≥n
round down since we cannot have a decimal desk
31 desks
but, the teacher has 1 desk also so add 1
31+1=32
Answer:
x = 9
Step-by-step explanation:
If g(x) = 3, that means that the output is three.
Outputs are y values.
Look at the graph. When y=3, the x = 9.
So the input value for which g(x) = 3 (aka that gives the output y = 3) is x = 9
Answer:
11
Step-by-step explanation:
248/24=10.3
round up to 11
<span>5 < 2x + 1 < 11 separate into inequalities
2x+1>5
2x+1<11 solve the inequalities
x>2
x<5 find the intersection
answer: x= (2.5)
I hope this helps :) (photomath is a really good app for math like this! It shows the works too!)</span>
