Answer:

a= 73.2

b =36.6

c = 76.2

Step-by-step explanation:

Perimeter of the triangle is the distance round the triangle.

Let the 3 sides be a, b and c

Side a of the triangle is twice as long as side b. This means

a = 2b

Side c is 3 feet longer than side a. This means

c = a + 3

The perimeter of the triangle is 93 feets. Formula for finding the perimeter of the triangle is

(a + b + c)/2

Therefore,

93 = (2b + b + 2b + 3)/2

93 = (5b + 3)/2

5b + 3 = 93 × 2 = 186

5b = 186 - 3 = 183

b = 183/5 = 36.6

a = 2b = 2 × 36.6 = 73.2

c = a + 3 = 73.2 +3 = 76.2

Needs to be in fraction form and simplified <br><br> 3 4/5 + 4 5/6 =? <br><br> 10 points
LenaWriter [7]

Answer:

259/30 or 8 19/30 depending on what format your teacher wants the answer

Step-by-step explanation:

First we can turn both mixed fractions into improper fractions and to do that we multiply the whole number by the denominator and that add that to the top number.  So for 3 4/5 we would multiply 3 and 5 and than add 4 getting us to 19/5 doing the same to 4 5/6 gets us to 29/6.  Now in order to add fractions we need to get a common denominator.  The least common multiple of 5 and 6 is 30 so we will multiply each fraction by whatever number will give us 30 in the denomiator.  for 19/5 that number is 6 so our new fraction is 114/30 and for 29/6 that number is 5 so our new number is 145/30.  Now we just add the numerators and simplify.  114/30+145/30=259/30

I hope this helps and please don't hesitate to ask if there is anything still unclear!
