The given equation is:
Just multiply both numerators and both denominators respectively, with the bar line still between them. So, it becomes
Then you factor out the equations:
Simplify terms by dividing them. The negative sign and 3 cancels out. The answer would be:
15 x 5 = 75
35/75 + 30/75 = 65/75
(65/75) / 5 = 13/15
Answer:t=5.1 (also the /means divide right if it does that's the answer)
Step-by-step explanation:
You seem to be saying that Y=4/X+SQRT X +0.2 -5X, and that x is given as 4/5. To evaluate <span>Y=4/X+SQRT X +0.2 -5X, replace each occurrence of x with 4/5:
y = 4 / (4/5) + sqrt(4/5) + 0.2 - 5(4/5)
= 5 + 2 / sqrt(5) + 0.2 - 4
Can you simplify this further?

Answer:
The original piece of wood is 108 cm
Step-by-step explanation:
From the given ratio, the shortest is of the ratio 5 and the longest is of the ratio 7
Let the original piece of wood be x
so the sum of the ratios will be;
5 + 6 + 6 + 7 = 24
the shortest length would be 5/24 * x
= 5x/24
the longest will be 7/24 * x = 7x/24
From the question;
7x/24 -5x/24 = 9
(7x-5x) = 24(9)
2x = 24(9)
x = (24 * 9)/2
x = 108 cm
