Cosα=x/L
x=Lcosα, we are told the ladder is 10ft and α=42.5 so
x=10cos42.5° ft
x≈7.37 ft (to nearest hundredth of a foot)
3 * 171 and you are going to get 513
a=4 , b=3 These values make the equation true .
<u>Step-by-step explanation:</u>
Here we have , If a and b are both integers and b does not equal 0, then -(a/b) = (-a)/b = a/(-b) Choose two values for a and b. We need to find if those values make the equation true . Let's find out:
We have the following equation:
-(a/b) = (-a)/b = a/(-b) , Let a=4 , b=3 , So
⇒
⇒
⇒
⇒ { Multiplying by -1 }
⇒
Therefore , These values make the equation true .
5x + 20 = 70
5x = 70 - 20
5x = 50
x = 50/5
x = 10
5(10) + 20 = 70
50 + 20 = 70
70 = 70
hope this helps :)
Y=8x because 42-26 is 16 and divide that by the difference between the hours to get how much you pay per hour
