Answer:
1. 81 2. -20 3. 168 4. -24
Step-by-step explanation:
I hope this is right :)
The mass of b equals the mass of d so
24(10-x)=6(x+15)
240-24x=6x+90
30x=150
x=5
mass of d is 6(5+15)=6*20=120
mass of c=180-mas of d=180-120=60°
Yes y is a function of x.
Rewrite the function using algebra to get this:
y = -x + 2
That forms an equation of a line whose slope is -2 and whose y-intercept is 2
Answer:
HCF of 120 and 180 is 60 and hence a measuring tin of 60 litre volume should be bought.
