The share of sand in the mixture is 3/7
To make 112 kgs. of concrete, he will need
3/7 x 112 = 48 units of sand
Answer:
The equation of the line will be:
Step-by-step explanation:
Given the points
Finding the slope




We know that the value of y-intercept can be obtained by setting x=0, and solving for y
Here,
at x = 0, the value of y = 0
Thus,
y-intercept = b = 0
We know the slope-intercept form of the line equation is

where m is the slope and b is the y-intercept
now substituting m = 0 and b = 0 in the slope-intercept form
y = mx+b
y = 0(x) + (0)
y = 0+0
y = 0
Therefore, the equation of line will be:
Answer:
the answer is x=0 and x=2
