First Equation:

0.6 +(0.4+0.9) =n

Step 1: do parentheses first:  

0.4+0.9 = 1.3

Step 2: Add 0.6 + 1.3

0.6 + 1.3 = 1.9

n= 1.9

Second Equation:

(1.57 + 0.75) + 0.25 + n

Step 1: do parentheses first:

1.57 + 0.75 = 2.50

Step 2: Add 2.50 + 0.25 = 2.75

Step 3: Add 2.75 and n = 2.75+n

Final Answer:

1.9 +2.75+n = 4.65 +n

Hope this helps!!

When buddy discovers the revolving door, he goes 4 complete revolutions in 11 seconds. How many times around would he go if he c
mezya [45]
To figure out how many revolutions Buddy goes in 1 minute, (60 seconds) we can use proportions

4 revolutions/11 seconds = x revolutions/60 seconds
When we cross multiply, (multiplying one numerator by the other denominator, and vice versa for the other numerator) we get
240 = 11x
divide both sides by 11 to get
21.81 = x
or 21 complete revolutions
