Answer:
r = -6
Step-by-step explanation:
6r + 7 = 13 + 7r
-6r both sides
7 = 13 + r
-7 both sides
r + 6 = 0
-6 both sides
r = -6
Answer:
67.53 kiloliters.
Step-by-step explanation:
We have been given that the capacity of the molten sea, a furnishing of the temple, is given as 2000 baths.
First of all, we will convert 2000 baths into gallons by multiplying 2000 with 8.92.
We know that 1 gallon equals 0.00378541 kiloliters, so we will multiply 17,840 by 0.00378541.
Therefore, the Molten sea hold 67.53 kiloliters.
We can find 20% of $7.95 as shown below:
Therefore, 20% of $7.95 would be $1.59.

Answer: the cost of each bush is $15
the cost of each flower is $2
Step-by-step explanation:
Let x represent the cost of each bush.
Let y represent the cost of each flower.
Portia bought 12 bushes and 30 flowers for $240 to plant in her yard. This is expressed as
12x + 30y = 240- - - - - - - - - - -1
Later, she realized she did not have enough plants and bought 7 more bushes and 10 more flowers for $125. This is expressed as
7x + 10y = 125- - - - - - - - - - -2
Multiplying equation 1 by 7 and equation 2 by 12, it becomes
84x + 210y = 1680
84x + 120y = 1500
Subtracting, it becomes
90y = 180
y = 180/90
y = 2
Substituting y = 2 into equation 1, it becomes
12x + 30 × 2 = 240
12x + 60 = 240
12x = 240 - 60 = 180
x = 180/12
x = 15
