You would need 14 cases. You multiply 150 times 2 to get 300 which is 2 cases of soap per day and you multiply 7 days in a week by 2 and you let math magic happen
Step-by-step explanation:
y = 400 × 0.75
y = 300
300 milligrams = 0.75 hours
x = 3 hours
3(300) = 0.75x
900 = 0.75x
x = 1200
Answer:
x = 4/7
y = 60/7
Step-by-step explanation:
3x + 4y = 36
y = x + 8
Substitute the second equation into the first since it already has the y isolated for you:
3x + 4(x + 8) = 36
3x + 4x + 32 = 36
7x = 4
x = 4/7
Take the answer you got from the equation above and plug that into the second equation:
y = 4/7 + 8
y = 60/7
To check just LS/RS both equations:
3(4/7) + 4(60/7) = 36
12/7 = 240/7 = 36
252/7 = 36
36 = 36
LS = RS
60/7 = 4/7 + 8
60/7 = 60/7
LS = RS
We know that, the sum of measures of supplementary angles is 180°
So, the Correct choice is :
because, 65° + 115° = 180°
Intersecting is where two lines cross at any angle.
Perpendicular means two lines cross at exactly a 90-degree angle
Parallel indicates that the two lines have the same slope and never cross.
