Answer:
The solution is (0, 4)
Step-by-step explanation:
Please pay attention to the first two equations and drop the last two:
12x−5y=−20 y=x+4 x=x=x, equals y=y=y should ideally be:
12x−5y=−20
y=x+4
Let's find x. Substitute x + 4 for y in the first equation, obtaining:
12x - 5(x + 4) = -20
Carrying out the indicated multiplication, we get:
12x - 5x - 20 = -20, or 7x = 0
If x = 0 then y must be 0 + 4, or 4.
The solution is (0, 4)
Answer:
Step-by-step explanation:
The smallest number I found was 59 which certainly is true.
The next one is 119
And a third one in this series is 179
I did this by brute force. In other words, I let a computer do all the counting and dividing.
Gotta convert this to make it save some time.
1 over 18 = 1/18
1 over 3 = 1/3
If 1/18 of a lawn is wattered in 20 mins, (Simply coverting 1/3 hr to mins by doing 60/3) 20 * 18 = 360 Mins = 6 Hours
It takes 6 hours to water the entire lawn
Answer:
Juanita’s recipe will have a stronger lemon flavor.
Explanation:
Juanita has a ratio of 4:2,where as Lydia has a ratio of 5:3. If you divide 4 by 2 and 5 by 3, Juanita will have a value of 2, and Lydia will have a value of 1.67.
