To solve an addition problem, you simply add one number to the other. For example,
If I want to add 4 to 5, I would write the equation 4 + 5 = 9.
To solve a subtraction problem, you simply take a number away from another. For example,
If I want to take 5 away from 9, I would write the equation 9 - 5 = 4.
Hope I helped! :)

Answer:
<h2><u><em>
$1.75</em></u></h2>
Step-by-step explanation:
if a wire of length 2 meters costs $10. find the cost of a wire of length 35cm $1.75
2m = 200 cm
200 : 10 = 35 : x
x = 10 * 35 : 200
x = 1.75
The mean speed of the 100 cars is 55.4
<h3>How to determine the mean?</h3>
The table of values is given as:
Speed (MPH) Cars
30-39 5
40-49 18
50-59 50
60-69 17
70-79 10
Rewrite the frequency table to include the class midpoints
x f
34.5 5
44.5 18
54.5 50
64.5 17
74.5 10
The mean speed is then calculated as:
So, we have:
Evaluate
Hence, the mean speed is 55.4

Answer:
142.66 cm
Step-by-step explanation:
If Angle VYT is 90 degrees:
√(95.2^2-34^2)=√7907.04 (YT)
√(168^2-√7907.04^2)=√20316.96 (YK)
√20316.96+34= about 142.66 (VY+YK) [X]
Hopefully that helped! :)
