Answer:
The perimeter of a rectangle is the sum of both lengths and both widths, which is equal to 54 meters. Let's call Length L and Width W.
The question is saying this: L = 3 meters + 3(W). We have 2 variables, which means we need at least 2 equations to solve. So far we have one, our second equation is from the perimeter.
2 lengths + 2 Widths = 54. Now, it's just a plug and chug.
2(3 + 3W) + 2W = 54.
6 + 6W + 2W = 54
8W = 48
W=6
L = 3 + 3(6) = 21
To double check: 2(21) + 2(6) = 42 + 12 = 54
The Width is 6 meters, and the Length is 21 meters.
Answer:
I only know that the first box is and it is counting by twos
Step-by-step explanation:
because 5+2 =7 then 6+4=10 then 7+6=13 then 8+8=16 and lastly 9+10=19
Answer:
2*2*9+4*12*3=36+144=180
Step-by-step explanation:
Answer:
ab=1/12
Step-by-step explanation:
1/(4ab)+1/(3ab)-1/(2ab)=12
1/(ab)*[1/4+1/3-1/2]=1/12
1/(12ab)=1/12
ab=1
Answer: the commission received by the salesperson is $576.9225
Step-by-step explanation:
Let x represent the auction price
At the dealership, a sales person sold the boat for 30% more than the auction price. It means that the amount for which he sold the boat is
x + (30/100 × x)
= x + 0.3x = 1.3x
If the dealer paid $10,000 for a boat at an auction, it means that
1.3x = 10000
x = 10000/1.3
x = 7692.31
The difference between the auction price and the dealer price is
10000 - 7692.31 =$2307.69
The sales person received a commission of 25% of the difference between the auction price and the dealer price. It means that the commission received by the salesperson is
25/100 × 2307.69 = $576.9225
