Answer: 160
Step-by-step explanation: 80+80=160
By similarity theorem, I will send you a picture when I'm done.
I hope that explains everything for you the value of x is 18 and I worked it out step by step for you so you would understand
Since rectangles have two pairs of equal-length sides, for any rectangle with length L and width W, its perimeter is always 2L + 2W (or 2(L + w), whichever you prefer). Here, we're told that the width is 4 feet less than the length. Symbolically, we'd say that W = L - 4. This allows us to write the perimeter entirely in terms of length if we replace our W with the expression on the right side:
2L + 2W = 2l + 2(L - 4) = 2L +2L - 8 = 4L - 8
Sam wants this expression to come out to 52, so we can set up the equality 4L - 8 = 52 and solve for L to find what the length has to be:
Adding 8 to either side, the equality becomes 4L = 60. Diving either side by 4 gives us L = 15, which tells us that the length of the deck should be 15 feet.
you can find a solution from any class of book from my point of the answer should be m29 = 80 than m=80 / 20 so it will give 20/19 m25 = 55 than m= 55 / 25 will give you 11 /5
Answer:
Step-by-step explanation:
<u>Method 1:</u>
$300 on school supplies
1/10 on notebooks
As you're finding how much is left:
10/10-1/10=9/10
Convert 9/10 into a decimal
9/10=0.9
300*0.9=$270
OR
<u>Method 2: </u>
1/10=0.1
300*0.1=$30
Take away 30 from $300
$300-30=$270
By using either method, You would still have $270 left.
How this helps!!!
Have a nice day :)
