(5x+7) + (8x-21) = 90
13x-14 = 90
13x= 104
X=8
The angle measurements are 47, and 43
The length is 24 because 768 is the are and to find area you would do length x width but in this case the width has already been told so you have:
32 X____=768
so you do 768÷32= 24 so that's your answer sorry for such a long explanation which probably wasn't necessary but oh well!
Answer:
Step-by-step explanation:
The expected return is given as
Expected Return = SUM (Return i x Probability i). i=1,2,3.....
First investment
Probability of 0.7, it returns 60cents per dollars
Second investment
Probably of 0.3, it loses 20cents per dollar.
Expected return=(0.7×60)-(0.3×20)
Excepted return= 42-6
Excepted return=36cents
To dollars, 1cents is 0.01dollars
Then, 36cents = 0.36dollars
Expected return=$0.36
Answer: X = 17
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(x−5)=24
(2)(x)+(2)(−5)=24(Distribute)
2x+−10=24
2x−10=24
Step 2: Add 10 to both sides.
2x−10+10=24+10
2x=34
Step 3: Divide both sides by 2.
2x
/2 = 34/
2
x=17
