Answer:

<u>x > 1/6</u>

Step-by-step explanation:

-2(8x-4)<2x+5

We open the brackets first

-16X + 8 < 2X + 5

Combine the like terms, we subtract 8 on both sides

-16x + 8 -8 < 2x +5 -8

-16 x < 2x -3

We subtract 2x on both side

-16x -2x < -3

-18 x < -3

simplify, by dividing both side by -18,

-18x/-18 <-3/18

x > 1/6 (reverse the sign to >)

<u>x > 1/6</u>

Answer:

Choice A is correct answer.

Step-by-step explanation:

Given inequalities is:

-2(8x-4) < 2x+5

We have to find the value of x.

-16x+8 < 2x+5

Adding 16x to both sides of inequalities , we get

16x-16x+8 < 16x+2x+5

0+8 < 18x+5

Adding -5 to both sides of inequality ,we get

-5+8 < 18x+5-5

3 < 18x

Multiplying by 1/18 to both sides of above equation,we get

1/18(3) < 1/18(18xx)

3/18 < x

Swapping sides,we get

x > 3/18

x > 1/6 which is the answer.

How much cream that is 30% butterfat must be mixed with milk that is 3% butterfat to make 45 gal of cream that is 12% butterfat?
pochemuha

Answer:

15 gallons

Step-by-step explanation:

If x is the gallons of 30% butterfat cream, and y is the gallons of 3% butterfat milk, then:

x + y = 45

0.30 x + 0.03 y = 0.12 (45)

Solve the system of equations with substitution or elimination.  Using substitution:

0.30 x + 0.03 (45 − x) = 0.12 (45)

0.30 x + 1.35 − 0.03 x = 5.4

0.27 x = 4.05

x = 15

You need 15 gallons of 30% butterfat cream.

How do you work out -4(-5-b)=1/3(b+16)
Umnica [9.8K]

First multiply the parenthesis:

20 - b = 1/3b + 16/3

Then combine like terms:

20 -b + b = 1/3b + b + 16/3

20 - 16/3 = 1/3b + b + 16/3 -16/3

20 - 16/3 = 1/3b + b

 44/3  =  4/3b

and if your looking for b;

44/3 (divided by) 4/3 = b

11 = b...is your final answer!

hope it helped :)
