The answer is 3/4. All you need to do is make proportion and simplify! Hope it helps!
Starting with

Divide both sides by 2 to get

If
is positive, this means

If
is negative, this means

So, we are looking for positive number smaller than 5, or negative numbers greater than -5. In other words, every number between -5 and 5 (both excluded) will satisfy the equation.
Answer:
n = 1
Step-by-step explanation:
4/5 - 3/5 = 1/5n
collect like terms
-3/5 = 1/5n - 3/5n
-3/5 = 1 - 4/ 5n
-3/5 = -3/ 5n
cross multiply
-15n = -15
Divide both sides by -15
n = 1
Answer:
4d + 6c - 6
Step-by-step explanation:
The perimeter of the rectangle is the sum of all 4 sides
perimeter = 2d - 3 + 3c + 2d - 3 + 3c = 4d + 6c - 6
Answer:L= 45cm
W=35cm
Step-by-step explanation:
P = 2l + 2w
2(l+w)= 160
l+w = 80
From the question,
l = w+9
So w+9+w = 80
w = 71/2 = 35.5 = 35 since it must be a whole number
l = 80- 35= 45cm
