You just have to imagine it as a rectangle, with a square.
The rectangle inside is 18" by 8".
The square, made of the outside two triangle pieces, is 8" by 4". (Yes, I know it isn't really a square.)
Area = length x width.
A1 = 18 x 8
= 144.
A2 = 8 x 4
= 32.
A1 + A2 = 176 square inches.
Answer:
3 people
Step-by-step explanation:
$51/$17 = 3 people
- We know to start with $51 dollars because that is the total price of the meal.
- We also know each meal costs $17.
- Next, ask youself what we are trying to find? We are trying to find how many people are eating.
- Therefore to find that we need to take our starting amount $51 divided by $17 because that is the cost of 1 meal.
- $51/$17 = 3 people (whole cost/individual cost = # of people)
- To check this take 3 x 17 = 51 (Now we know it is correct)
- If you would like a further explanation please let me know.
The answer to the problem is 13/72
200 +6m = 500-6m
add 6m to each side
200+12m = 500
subtract 200 from each side
12m = 300
divide both sides by 12
m = 300/12 = 25
25 minutes
check:
200+ 25*6 = 200 +150 = 350
500 - 25*6 = 500-150 = 350
It is the Correct answer hope this help you
Be happy
