3/4 - 1/3 = 9/12 - 4/12 = 5/12
(5/12) / 10 = 1 / x
5/12x = 10
x = 10* 12/5
x = 120/5 = 24 gallons...so when full, the tank holds 24 gallons
so if it is already 3/4 full, then u just need 1/4 to fill
1/4(24) = 24/4 = 6......so u would need 6 more gallons to fill the tank up to full capacity.
Answer:
the value of x is 1
Step-by-step explanation:
cross multiply them
2x+10=12x
then take 2x to right hand side
10=12x-2x
then
10=10x
divide 10 on both sides
10/10=10x/10
then it is
1=x
The answers to the questions
Answer:
x=4.875
y=-0.25
Step-by-step explanation:
4x – 2y = 10
2x-y=10
y=2x-10
4x + 6y = 18
2x+3(2x-10)=9
8x=39
x=4.875
y=2(4.875)-10
y=-0.25
If (x+4)(x+9) then either x+4 = 0 or x+9 = 0
This is by the zero product property
