B. 1/2 of 4/5 = ____ fifth(s)
MrRissso [65]

Answer:

2 because of the way the question is written

2/5 if you get 2 wrong.

Step-by-step explanation:

1/2 * 4/5  of means multiply

numerator:  1*4 = 4

denominator = 2 * 5 = 10

Answer: 4 / 10 but this will reduce. Divide Top and Bottom by 2

4/2 = 2

10/2 = 5

Answer: 2/5

The way you should answer is 2 because the question gives you the fact that it is in 5ths. If you get it wrong then put in 2/5.

The perimeter of a triangle is 65 meters. The second side is 5 meters less than the first side The third side is 7
tangare [24]

Answer:

The length of each side is 31.5m, 26.5m, 7m

Step-by-step explanation:

Let the length of the first side of the triangle be x meters.

Then, the second side is x-5 meters.

The third side is given as 7 meters.

The perimeter is 65 meters

This gives us the equation:

65 = x + x - 5 + 7

65 - 7 + 5 = x + x

63 = 2x

x =  \frac{63}{2}  = 31.5

The length of each side is 31.5m, 26.5m, 7m
