Mathematics
1 answer:
Andrew [12]3 years ago

Answer:

  • 24 ounces of solution B
  • 16 ounces of solution A

Step-by-step explanation:

The largest contributor of salt to the mix is the 45% solution (B), so we'll let our variable (b) represent the quantity of that. The total amount desired is 40 ounces, so the quantity of solution A is (40-b) ounces. Then the amount of salt in the mix is ...

  0.45b +0.20(40-b) = 0.35(40)

Simplifying and subtracting 0.20(40), we get ...

  0.25b = 0.15(40)

  b = 40(.15/.25) = 24

  (40-b) = 16

The scientist should use 24 ounces of Solution B and 16 ounces of Solution A.

32+2/3(21y-6) in factored form
artcher [175]

Answer:

14(y + 2).

Step-by-step explanation:

32 +2/3(21y - 6)

Distributing the 2/3 over the parentheses:

= 32 + 2/3*21y  + 2/3 * -6

= 32 + 14y - 4

= 14y + 28

= 14(y + 2).

What is the x- intercept of -2x+5y=-10?
disa [49]
To find the x-intersept, just set y = 0 into the equation, then solve it for x:

-2x + 5 * 0 = -10

-2x + 0 = -10

-2x = -10

x = (-10)/(-2)

x = 5 <----- this is the answer.


I hope this helps. =)
