Answer:
x>-1
Step-by-step explanation:
5-2x<7
Subtract 5 from each side
5-5-2x<7-5
-2x < 2
Divide by -2
Remember that flips the inequality
-2x/-2 > 2/-2
x> -1
Answer:
112 m
Step-by-step explanation:
Scale drawing :
1 centimeter : 8 meters
This can be interpreted to mean that ;
1 centimeter in the drawing corresponds to 8 meters of the actual length of the field.
Hence, if soccer field has a drawing length of 14 centimeters
The actual length of the field will be, x :
1 = 8
14 = x
Cross multiply :
1 * x = 8 * 14
x = 112
Hence, actual. Length of the field = 112 meters
You would need to use the pythagorean theorum which is would be 8 squared +x squared = 15 squared
<h3>
Answer: 0.157</h3>
========================================================
Explanation:
Convert the fraction 9/50 to decimal form. You can use either long division or a calculator.
You should find that 9/50 = 0.18 which is the same as 0.180
So the original compound inequality is the same as saying 0.125 < x < 0.180
This tells us that x is between 0.125 and 0.180 where x is not equal to either endpoint. We simply need to pick anything in this interval. It can be anything you want (I recommend to use a number line to help pick a value). One such value is 0.157. There are infinitely many values you can select from.
The number 0.157 is between 0.125 and 0.180, ie 0.125 < 0.157 < 0.180
It's very similar to saying 157 is between 125 and 180, ie 125 < 157 < 180.
I don’t get it please explain more
