lys-0071 [83]

Answer:

\large\boxed{-6y^2+12y+4}

Step-by-step explanation:

(2y^2+7y+11)-(8y^2-5y+7)\\\\=2y^2+7y+11-8y^2-(-5y)-7\\\\=2y^2+7y+11-8y^2+5y-7\qquad\text{combine like terms}\\\\=(2y^2-8y^2)+(7y+5y)+(11-7)\\\\=-6y^2+12y+4

The mean of four positive integers is 5.
a_sh-v [17]

Answer:

(x1 + x4)/2 = 4

Step-by-step explanation:

(x1 + x2+ x3 + x4)/4 = 5         mean

x1 , x2 , x3 , x4

median (x2+x3)/2 = 6

(x2+x3) = 12

The smallest integer is x1, the largest integer x2.

The mean of the largest and smallest of the integers is (x1 + x2)/2.

(x1 + x2+ x3 + x4)/4 = 5  

x1 + x2+ x3 + x4 = 20

x1 + 12 + x4 = 20

x1 + x4 = 20 - 12

x1 + x4 = 8

(x1 + x4)/2 = 8/2

(x1 + x4)/2 = 4

7. How much 6% solution can you make by diluting 350 mL of a 15% solution
ANTONII [103]

Answer:

We know that the formula to mix chemical solutions is: C1V1 = C2V2

where C represents the concentration of the solute, and V represents volume in milliliters or ml.

In this case, we have:

0.06V1 = 0.15×350

Solving for 'V1' we have:

V1 = (0.15×350)/0.06 = 52.5/0.06 = 875

Therefre I can make 875 mL of a 6% solution by diluting 350 mL of a 15% solution.
