b) 1/18
Answer:
Numbers are 28 and -15
Step-by-step explanation:
Mark first number X, and second number Y, then:
x-y=43
and
x+y=13
We get system of two equations. Solve it by add both them together:
x-y+x+y=43+13
2x=56
x=28 we get first number
x+y=13
28+y=13
y=13-28
y=-15
Answer:
dimensions = 10.8 X 4
Step-by-step explanation:
Breadth/ width of room = x
Length of room = 6.8 + x
perimeter = 2 ( L + B )
29.6 = 2 ( 6.8 + x + x )
29.6/2 = 6.8 + 2x
14.8 - 6.8 = 2x
8 = 2x
8/2=x
4=x
Length of room = 6.8 + x = 6.8 + 4 = 10.8 m
Breadth/ width of room = x = 4m
