If G is the midpoint of FH, FG= 14x + 25 and GH = 73- 2x, find FH
Alenkinab [10]
Given that G is the midpoint of FH, then:
FG=GH
hence;
14x+25=73-2x
solving for x we get:
14x+2x=73-25
16x=48
x=48/16
x=3
therefore the length FG=14x+25 will be:
14*3+25
=67
hence FH will be:
FH=67*2=134

If i have a fish tank is 1/3 full of watet. If i add abither, 4 gallins of water it will be comoletely full. How many gallons wo
tresset_1 [31]

Answer:

1/2 gallons

Step-by-step explanation:

since 1/3of the tank is already full and another 4 gallons fills it up

4 gallons= 2/3 of the tank or the tank is 6 gallons total

75% is equal to 3/4

6*3/4=4 1/2 gallons

since it is 1/3 or 4 gallons full

4 1/2 -4= 1/2

What are the answer to this question
IrinaK [193]

Answer: t=-3h+25

Step-by-step explanation:

t=-3h+25

25 degrees is a constant-- it never changes, no matter how many hours goes by. So, you don't multiply a variable with it.

The temperature drops every 3 hours-- this is not constant, since it's dependent on the number of hours that passes. So, use a variable here. Since the temperature drops every three hours, it's -3, and not 3.
