Answer:
50 gallons 20%
50 gallons 30%
Step-by-step explanation:
If x is gallons of 20% moonshine, and y is gallons of 30% moonshine, then:
x + y = 100
0.20x + 0.30y = 0.25(100)
Solve the system of equations using substitution or elimination. Using substitution:
0.20x + 0.30(100 − x) = 0.25(100)
0.20x + 30 − 0.30x = 25
5 = 0.10x
x = 50
y = 50
Answer:
152 m²
Step-by-step explanation:
<u>Area of flower garden</u>
Assuming the flower garden is <u>rectangular</u> and its dimensions are measured in <u>meters</u>:
- width of garden = 14 m
- length of garden = 20 m
<u>Total area of path and garden</u>
If there is a 2 m wide path <u>all around the garden</u>, the dimensions of the total area will be the dimensions of the garden extended by 4 m:
- width = 14 m + 2 m + 2 m = 18 m
- length = 20 m + 2 m + 2 m = 24 m
<u>Area of path</u>
To calculate the <u>area of the path</u>, subtract the <u>area of the garden</u> from the <u>total area</u>:
Answer:
(1)
(2)
We can solve for y from equation (1) and we got:
(3)
And replacing (3) into (2) we got:
And solving for x we got:
And solving for y from (3) we got:
And the solution would be x = 50 and y =75
Step-by-step explanation:
For this problem we have the following system of equations:
(1)
(2)
We can solve for y from equation (1) and we got:
(3)
And replacing (3) into (2) we got:
And solving for x we got:
And solving for y from (3) we got:
And the solution would be x = 50 and y =75
Answer:
99
Step-by-step explanation:
99 because x= 10 so 10 times 10 is 100 - 1 will = 99
