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 =
∴ x = <u>9 labours</u>

The answer is 22.
Step-by-step explanation:
Just well use a calculator. If you don't have that then use PEMDAS. Hope it helps.
The answer and work is in the SS below
Answer:
$3.30
Step-by-step explanation:
2.60*6= $15.60 beads per necklace
35.40-15.60= $19.80 total pendant
19.80/6= $3.30 per pendant
You do 5 multiple by 2 + 2. 4 multiple by 3 + 3. 12 multiple by 15 is 180
