Step-by-step explanation:
9 times 12 is 108 -> 108 - 60 = 1 hour and 48 minutes -> 48 plus 4 = 7:52am
Answer:
(6,3)
Step-by-step explanation:
y=2/3 x - 1
y=-1/2 x + 6
Since both equations are equal to y, we can set them equal
2/3 x - 1 =-1/2 x + 6
We have fractions, so I will multiply by 6 to clear the fractions
6(2/3 x - 1) =(-1/2 x + 6)6
Distribute
4x -6 = -3x +36
Add 3x to each side
4x+3x -6 = -3x+3x +36
7x -6 = 36
Add 6 to each side
7x-6+6 = 36+6
7x = 42
Divide each side by 7
7x/7 = 42/7
x =6
Now we need to find y
y =2/3x -1
y = 2/3(6) -1
y = 4-1
y=3

A gallon of gasoline cost 30 cents in 1960 an
$1.30 in 1980
percent increase in the price = ?
first we have to convert cents into dollars so that both amounts have to be in same unit
30 cents = $0.3
increase in gasoline cost = $1.30 - 0.3 = $1
now for calculating percent increase divide this with the new amount and than multiply with 100
percent increase = ($1 / $1.30) x 100 = 76.92% = 77% approx.
so, there is 77% increase in the price of gasoline
