Answer:
7.5kg
Step-by-step explanation:
Given that:
Monday:
Mass of sand = 24 kg
Mass of cement = 5 kg
Tuesday :
Mass of sand = 36 kg
Let mass of cement = c
Mass of cement required to make the same type of mortar mix
Mass of Sand = mass of cement
24kg = 5kg
36kg = c
By cross multiplication :
24 * c = 5 * 36
24c = 180
Divide both sides by 24
c = 180 / 24
c = 7.5 kg
Hence mass of cement required is 7.5 kg
Answer:
C) The solution for the system of equations
Step-by-step explanation:
Point (3, 120) is where both lines intercept!
Basically, (3, 120) is where both equations are equal to each other.
(120 = 20(3) + 60) = (120 = 40(3))
We can test it!
120 = 20(3) + 60
120 = 60 + 60
120 (Correct)
120 = 40(3)
120 = 120 (Correct)
Answer:
The slope of the line represented by y = -5x is "-5".
Step-by-step explanation:
y=mx+b
M=slope
b=Y-intecerpt
