Answer:
A=330
Step-by-step explanation:
im not sure which is the length width height
but if length is 10
width is 3/5
height is 15
A=2(wl+hl+hw)=2·(0.6·10+15·10+15·0.6)=330
then the area would be 330
Answer:
y=18.2
Step-by-step explanation:
-3x+5y=22
-3(37-14)+5y=22
-69+5y=22
5y=91
y=18.2
check:
-3(37-14)+5(18.2)=22
-69+91=22
22=22

======================================
Explanation:
7+6 = 13. Divide this over 5 to get 13/5 = 2 remainder 3. The quotient 2 is something we don't care about. <u>We only worry about the remainder</u>. Therefore 7+6 = 3 (mod 5)
-------------
2+1 = 3 (mod 5) for similar reasoning as above. 3/5 = 0 remainder 3.
-------------
20 = 9 (mod 11) since 20/11 = 1 remainder 9. Imagine you had 20 cookies and 11 friends. Each friend would get 1 whole cookie (quotient) and there could be 9 left over (remainder).
-------------
35/11 = 3 remainder 2
Or you could use repeated subtraction like so to find the remainder
35-11 = 24
24-11 = 13
13-11 = 2
The last result (2) is smaller than 11, so we stop here and this is the remainder.
Therefore, 35 = 2 (mod 11)
--------------
Here's another way to think of it. Consider you have $35 in your pocket. Let's say a store is selling trinkets for $11 each. We can pose these key questions:
- What is the most number of trinkets you can buy?
- If you buy that max amount, how much will you have left over?
The answer to the first question is 3 trinkets because 3*11 = 33 dollars is under the budget of $35. The amount left over is 35-33 = 2 dollars which is the remainder. It's not larger than 11, so we cannot buy any more trinkets at this point.
Answer: -7 is the answer
Step-by-step explanation:
4(2)+3(2-7)
2-7 is -5
-5 times 3 is -15
4 times 2 is 8
-15+8=-7
Answer:
209$ CAMPING COST/11$ PER NIGHT
Step-by-step explanation:
YOU WOULD SUBTRACT 233 FROM 442 YOU WOULD GET 209. THEN DIVIDE 19 INTO 209 YOU WILL GET 11
