Step-by-step explanation:
you know by using the x and y coordinates of the point in the equations and see, if both equations are still true.
if yes, it was a solution, and if just only one is false, then it was not a solution.
(3, -2) in
y + 4x = 10
5x - y = 13
so,
-2 + 4×3 = 10
-2 + 12 = 10
10 = 10 true
5×3 - (-2) = 13
15 + 2 = 13
17 = 13 false
so, it was NOT a solution.
Answer:
25 seconds
Step-by-step explanation:
The radius of a hailstorm varies directly
with the amount of time that it was in a cloud.
Radius = k x Time (in the cloud)
k is the constant of proportionality
R = k x T
0.5 = k x 10
k = 0.5/10
k = 0.05
Formula: R = 0.05 x T
1.25 = 0.05 x T
Time = 1.25/0.05
Time = 25 seconds.
Hope this helps :) !
12/25 is 48% becuase 12/25 is alao 48/100 because 12 x 4= 48 and 25 x 4= 100.
Answer:
1. 75% of 10 liters of milk = 0.75 * 10 liters of milk = 7.5 liters of milk
