A. A= ray and r=2
That’s the answer
Answer:
Step-by-step explanation:
Ok so the beaker is 200 water:800 acid
So she drains 100 from the acid and 100 from the water which equals
100:700
Then she adds 200 water:
300:700
there is 300 mL water in da beaker now
i might got it wrong tho
There are 714 boys in 'your' school, just cross multiply and divide to find your answer. x / 1309 = 6/11 is your formula; 1309 times six is 7854, then divide your product (7854) by 11 to get 714 as x or the number of boys.
Answer:
x+3y = 6
or, x = 6-3y.................(1)
3x+5y =6..........(2)
Substituting x = 6-3y in equation (2),
3 (6 - 3 y)+5 y =6
or, 18 - 9y +5y=6
or, y = 3
x = 6 - 3y = 6- 3.-3 = -3
Answer:
Step-by-step explanation:
Please use " ^ " to denote exponentiation: f(x)= 3x^2 - 6.
f(x)= 3x^2 - 6 can be factored (not solved) as follows:
f(x)= 3(x^ 2 -1) = 3(x - 1)(x + 1).
If you want a "solution," you must set f(x)= 3(x^ 2 -1) = 3(x - 1)(x + 1) = to 0 and solve the resulting equation for x: x = 1 and x = -1.
