-44>-2x-8

Add 8 on both sides

-36>-2x

Divide by -2 dice your x can't be negative

18<x

The sign flips when you divide by a negative. Therefore if the question is a true or false question, the answer would be false

Answer: 18 ≤ x < 0

Step-by-step explanation:

-44 > -2x - 8 ≥ -8

-36 > -2x ≥ 0 added 8 to all three sides

18 < x ≤ 0 divided all three sides by -2 (which flips the inequality signs)

Number 6 part a & b Number 7 Please & thank you

miv72 [106K]

Answer:

6- Part A: $750a+1200r=1000000$

Part B: $1065a+876r=1000000$

Solution of the system: $a\approx521.739\;\;\;\;b\approx507.246$

Step-by-step explanation:

Part A:

In words, the equation is formed like this:

Total kg of Arabica + Total kg of Robusta = Total kg of coffee

Now, the total of each yield is calculated by the product of kg/hectare and number of hectares. Thus, the equation is:

$750a+1200r=1000000$

Part B:

In words:

Arabica's worth + Robusta's worth = plantation worth

Each yield's worth is given by the product of the price per kg and the corresponding production. So, the equation is:

$1.42(750a)+0.73(1200r)=1000000\\1065a+876r=1000000$

How many sets of 2/12 are in 9/12

Vinil7 [7]

We can solve this problem by dividing 9/12 by 2/12. We should do this because to find how many sets of something are in a number, the question is asking us to do division. Doing this, we get 9/12 * 12/2, giving us our answer of 4.5 sets of 2/12 in 9/12.
