Answer:
28 years
Step-by-step explanation:
Sum of the years of Lance , Ted, Rosalinda = 39 + 22 +45 = 106 year
Sum of the years of Lance , Ted, Rosalinda & Erik = 33.5*4 = 134.0 year
Age of Erik = 134 - 106 = 28 years
Answer:
10 weeks
Step-by-step explanation:
20x+50=250
First subtract 50 from both sides, which gives you 20x=200
then divide 20 from both sides which gives you x=10
x²/2 =271 represents the situation where taking length twice as breadth and area as 271 ft² .
Area of a figure is the amount of space acquired by the figure
Area of a rectangle=Length x breadth
length=x
breadth=x/2
Area of rectangular lawn=lxb
=x.x/2
But as per question,
Area=271 ft²
⇒x²/2=271 1
⇒x=23.28 ft²
Therefore, x²/2 =271 represents the situation where taking length twice as breadth and area as 271 ft² .Value of x i.e. length is 23.28 ft²

Answer: x = 38.4
Step-by-step explanation:
7-x/3 = -1-x/8
1. Add 1 to both sides
8-x/3 = -x/8
2. Add x/3 to both sides
8 = x/3 - x/8
3. Multiply x/3 by 8/8 and x/8 by 3/3 to get the same number under the quotient
8 = 8x/24 - 3x/24
4. calculate the difference between 8x/24 - 3x/24
8 = 5x/24
5. Multiply both sides by 24/5, and there is the answer
38.4 = x
