Answer:
3/2= 1 1/2
Step-by-step explanation:
on the chart the x goes on the top and y on the bottom so the answer is 1 1/2.
102.02 / 4.011 =25.4350536
rounded 25.43
or 25
Answer:
50Hz x .10m = 5 m/s
20 m/s divided by .50m = 40Hz
80 m/s divided by .20m = 400Hz
120 m/s divided by .40m = 300Hz
340 m/s divided by 440Hz = .77m
That's a hard one either c or d
Distribute 1/4 to all terms within the parenthesis
9 - 5 = 4
1/4(16x + 60) = (16x + 60)/4 = 4x + 15
4 = 4x + 15
Isolate the x. Note the equal sign. What you do to one side, you do to the other.
Subtract 15 from both sides
4 = 4x + 15
4 (-15) = 4x + 15 (-15)
4 - 15 = 4x
-11 = 4x
Isolate the x. Divide 4 from both sides
(-11)/4 = (4x)/4
x = -11/4
hope this helps
