Answer: 20+(-35)

<em><u>Step-by-step explanation:</u></em>

a.) -20+10

You owe me 20 dollars and you gave me 10 dollars already so how much more do you owe me? If you got you owe me 10 dollars, then you are correct. So the answer is -10 because the amount you owe is what still needs to be given so it is negative. (-10)

b.) 20+(-35) or 20-35

This problem would be you gave me 20 dollars but then took 35 dollars from me so how much do you owe you. You owe me 15 dollars since you gave me $20 a while ago and took from me. This would be a negative 15 since you owe it to me. (-15)

-15 is less that -10 since you would owe me more if you owed me 15 dollars. Also, -10 is closer to 0 than -15.

What is x if x/5 =-9
Leona [35]

Answer:

x = -45

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Multiply 5 to both sides:

(x/5) * 5 = (-9) * 5

x = -9 * 5

x = -45

x = -45 is your answer.

6 labour complete a work in 12 days. How many labours should added to complete the works in 8 days?​
mario62 [17]

Answer:

9 labours

Step-by-step explanation:

In order to solve this, we must know which kind of proportionality is this. There are two types of proportions, direct and indirect/inverse proportions. In direct proportion, if one quantity increases, the other quantity also increases.

In indirect proportion, if one quantity increases, the other decreases and vice versa.

As per this question, we know if the number of labour increases, the number of days to complete a work decreases, thus proving that this is an indirect/inverse proportion.

6 labours => 12 days

x labours =>  8 days

Since its an inverse proprotion, multiply 6 with 12, and x with 8.

8x = 6 × 12

x = \frac{6*12}{8}

∴ x = <u>9 labours</u>
