Let us assume that the age of Janet's sister is = x
Then the age of Janet = x + 5
Now we also know that their combined age is equal to 51 years. Then we can write the equation as
x + (x + 5) = 51
2x + 5 = 51
2x = 51 -5
2x = 46
x = 46/2
= 23
So the age of Janet = x + 5
= 23 + 5
= 28 years
So the age of Janet's sister is 23 and Janet's age is 28
Answer: It 6 your wellcome :)
The length of given frame is 7 inches
The width of given frame is 5 inches
Assume the thickness of frame is 1 inches (as it is not clear in picture)
Area of square will be 7*5= 35 sq.inch.
Area of hollow surface 5*3= 15 sq.inch.
Area of frame = square area- hollow area= 35-15
Area of wooden portion of frame = 20 sq.inch.
Y = 1.5x + 6.5
hope this is helpful!
