Step-by-step explanation:
houses/hours
130/2.5= 312/x
(cross multiply)

6 = h
Answer:
X=6
Step-by-step explanation:
5(x-1)+3x=7(x+1)
5x-5+3x=7x+1
8x-5=7x+1
8x-7x=1+5
X=6
So the answer is X=6
Answer:
Yes
Step-by-step explanation:
f(x)=3 x-2
y= 3 x-2
x= 3y - 2
3 y -2 = x
3 y -2 + 2 = x + 2
<u>3 y </u> = <u>x </u> + <u>2</u>
3 3 3
<u>3 y </u> = <u>x </u> + <u>2 </u>
3 3 3
y = <u>x </u> + <u>2 </u> replace y with f ^ -1(x)
<em> </em> 3 3
f ^-1 (x) = <u>x</u> + <u>2 </u>
3 3
Answer:
1/10
Step-by-step explanation:
To find the number of red guppies, multiply the fractions.
Gary has 2/5 of his fish collection as guppies. Of the guppies, 1.4 are red.
So 2/5 * 1/4 = 2/20 = 1/10.
