What is 4 over 15 plus negative 7 over 45
IgorLugansk [536]

Answer:

If what I think youre saying is correct, then it should be 1/9

Step-by-step explanation:

4/15 + (-7/45)

Multiply both numerator and denominator of 4/15 by 3 so that the denominator becomes 45 to match the other fraction.

12/45 + (-7/45)

As the fraction on the right side is negative, it is taken away from the left fraction, hence:

(12 - 7)/45

Therefore, with simple subtraction,

5/45

Simplify to 1/9

The second side of a triangle is 4cm longer than the first, The third side is 1 less than twice the first, The perimeter is 55cm
lisov135 [29]

Answer:

13 , 17 and 25 cm.

Step-by-step explanation:

Let the length of the first side be x cm.

Then the second is x+4 and the third is  2x-1 cm long.

As the perimeter = 55 cm we have the equation:

x + x + 4 + 2x - 1 = 55

4x + 3 = 55

4x = 52

x = 13 cm.
