Answer:
(-5,24)
Step-by-step explanation:
2f+3g-h
first we substitute in the numbers
2(-3)+3(1)-2
-6+3-2
-3-2
-5
Then again
2(5)+3(4)-(-2)
10+12+2
22+2
24
hope this helps!:)
All you would have to do is look at the 2 in the place of the thousands which equals 2000, then look at the 2 that is in the place of the tens, which equals 20, so (this might get complicated) 2000/20 is... (If you need more help just tell me)
I would put the equation into two fractions to make a proportion.
30/24 = 20/x
From there, you'd cross multiply to get:
30x = 480
x = 16
So, if there are 20 children currently in the elevator, 16 adults can still enter.
Answer:
x= -4/6 or -2/3
Step-by-step explanation:
4-6x=8
-6x=4
x= -4/6 or -2/3
Answer:
f(x)=7x−4 f ( x ) = 7 x - 4. Replace f(x) f ( x ) with y y . y=7x−4 y = 7 x - 4. Interchange the variables. x=7y−4 x = 7 y - 4. Solve for y y .
