Answer:
x + 2y = 4
x − y = − 3
x − y =9 , x + y=6
x + y =4,
x− y =2
Step-by-step explanation:
[4.6+2×(5_2)]÷2=7
4.6+2=4.8
4.8×5=240
240_2=238
238÷2=116
Answer:
65 in and 39 in respectively
Step-by-step explanation:
Let r be the common ratio; when we multiply both L and R by this common ratio, we'll get the actual length and actual width of the rectangle, Recalling that the formula for the perimeter of a rectangle is P = 2L + 2R, we get:
2(5r) + 2(3r) = 16r = 208 in
Then r = 208/16 = 13
Thus, the actual length is 5(13 in) and the actual width is 3(13 in.),
or 65 in and 39 in respectively.
As a check, calculate 65 in / 39 in; this comes out to 5:3, as required.
Then
