Dash asked Lily to cut 5 equal-sized pieces of string for the holiday balloons. Lily only has 3 4/5 meters of string total. What length does each piece of cut string need to be?

19/25 metres

Step-by-step explanation:

From the question, we are given;

Total length of the string = 3 4/5 metres

If the string is cut into 5 equal size, the length of each piece will be expressed as;

Length of each piece = Total string length/5

Length of each piece = (3 4/5)/5

Length of each piece = 19/5 ÷ 5

Length of each piece = 19/5 ×1/5

Length of each piece = 19/25 metres

Hence the length of each piece she cut is 19/25 metres

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
