A number is 3 1/3 greater than another. If the sum of the numbers are doubled the answer would be 19 1/2
Delicious77 [7]

Answer:

smaller number = 3 5/24

larger number =  6 13/24

Step-by-step explanation:

let the larger number = x

smaller number = y

x - y = 3 1/3 equation 1

2(x +y) = 191/2 equation 2

divide equation 2 through by 2

x + y = 9 3/4  equation 3

subtract equation 1 from 3

2y = 6 5/12

y = 77/12 x 1/2 = 3 5/24

substitute for y in equation 1

x - 3 5/24 = 31/3

x = 3 1/3 + 3 5/24

x = 6 13/24

What is the length of the missing leg? If necessary, round to the nearest tenth.
KengaRu [80]

<u>Answer:</u>

  • a = 3.5

<u>Step-by-step explanation:</u>

<u>Let's find 'a' using Pythagoras theorem.</u>

  • => 4² = 2² + a²
  • => 16 = 4 + a²
  • => 12 = a²
  • => a = √12
  • => a = √2 x 2 x 3
  • => a = 2√3
  • => a = 2 x √3
  • => a = 2 x 1.732
  • => a = 3.464 = 3.5 (Estimated)

Question: find the value of x.<br><br><br> CAN someone please help me please explain!!
ELEN [110]

Step-by-step explanation:

Sum of interior angles of a polygon is given by (n-2)180°

where,n is the number of sides.

Since this polygon has 5sides,

sum of the interior angles = (5-2)180°=540°

x+150°+120°+75°+60°=540°

x°=540°-405° = 135°
