Answer:
1. The unit or resistance is Omega
2. The symbol is Ω
The best method would be to cross-multiply. Multiply the figure on the top left with the bottom right. Then set it equal to the multiplication of the bottom left with the top right.
This would turn into:
-1(x-1)=2(x+3) Then distribute the multiplication through the parentheses.
-x+1=2x+6 Next, get all the variables on one side, and the integers on another.
2x+x=1-6
3x= -5
x= -5/3
Answer:
4 2/3 gallons of gas
Step-by-step explanation:
Step 1
Suppose a car gas tank holds 21 gallons of gas.
On a trip it uses 2/3 of a tank of gas on a trip.
= 2/3 × 21 gallons of gas
= 14 gallons of gas
Step 2
Then it uses 1/3 of what is left in the tank.
The number of gallons of gas left =
21 gallons of gas - 14 gallons of gas
= 7 gallons of gas
Hence, this is calculated as:
1/3 × 7 gallons of gas
= 2 1/3 gallons of gas
Step 3
How many gallons of gas are left in the tank?
This is calculated as:
7 gallons of gas - 2 1/3 gallons of gas
= 7/1 - 7/3
Lowest common denominator =
= 21 - 7/3
= 14/3
= 4 2/3 gallons of gas is left
Therefore, 4 2/3 gallons of gas is left.
Answer:
How many sides are there?
Step-by-step explanation:
Answer:
$4,590
Step-by-step explanation:
Because you add the percenteages and multiply by amount overall.
