Answer:24
Step-by-step explanation:
18:27=16:__ let__=h
18:27=16:h
18/27=16/h
Cross multiply
18 x h=16 x 27
18h=432
Divide both sides by 18
18h/18=432/18
h=24
7+d=19 is the answer
subtract 7 from each side d=19-7
d=12
Answer:
x = -86
Step-by-step explanation:
60+ (-86)= -26
Answer:
Step-by-step explanation:
Let the length b y
Width = 2x - 3
Perimeter = 18x + 4
And
Perimeter = 2(l + w)
18x + 4 = 2(y + 2x - 3)
Dividing through by 2
9x + 2 = y + 2x - 3
Making y as subject
y = 9x - 2x + 2 + 3
y = 7x + 5
The missing side is 7x + 5
