X= -2 + the root of 5
OR
x= -2 - the root of 5
Answer:
10 miles
Step-by-step explanation:
Setting up an equation where the variable 'x' = the number of miles, we can find the total mileage for the passenger's trip:
$6 = $0.75x + $2.25
$6 = the total amount of the trip
$0.75 = the cost for each mile after the initial 5 miles
$2.25 = the flat fee for the first 5 miles
Solve for 'x', subtract $2.25 from both sides: 6 - 2.25 = 0.75x + 2.25 - 2.25 or 3.75 = 0.75x
Divide by 0.75: 3.75/0.75 = 0.75x/0.75 or x = 5 miles
Since the passenger was charged in additional 5 miles, then the total mileage is 10 miles.
Answer:
as isyllus says, Set the product of 7 and 24 equal to the product of 8 and x, and then solve for x.
Step-by-step explanation:
We given the fraction to be solved:
Using cross multiplication method:
i.e. Numerator of Left Hand Side term to be multiplied with Denominator of Right Hand Side term and put equal to multiplication of denominator of Left Hand Side term to Numerator of Right Hand Side term.
So, the first step to be carried out as per cross multiplication method:
Set the product of 7 and 24 equal to the product of 8 and x, and then solve for x.
Step-by-step explanation:
Set up a proportion.
12 cupcakes/ 0.5 hrs= 144 cupcakes/ x hrs
12*12=144
0.5*12=6=x
Final answer: 6 hrs
Answer:
Let SHPIX =x =$6000
Let RYURX=y=$3000
Let RYIHX=z =$3000
Step-by-step explanation:
y=z eqn..1
x+y+z=$12000 eqn..2
0.06x+0.05y=$510 eqn..3
From equation 2,x=12000-y-z eqn..4
Since y=z,eqn..1 becomes x=12000-2y..eqn 4
Substitute equation 4 into equation 2
0.06(12000-2y)+0.5y=510
720-0.12y+0.5y=510
720-0.07y=510
0.07y=720-510
0.07y=210
divide both sides by 0.07
y=210/0.07
y=$3000
since y=z
Then z=$3000 as well
Finally x+$3000+$3000=$12000
x+$6000=$12000
x=$12000-$6000
x=$6000
