Answer:
x = 13.5 is the correct value in the given expression.
Step-by-step explanation:
Here, the given expression is: 2(x-6)+5=20
Now, the DISTRIBUTIVE PROPERTY states:
A (B - C) = AB - AC
Now, simplifying the given expression, we get
2( x - 6) + 5 = 20 ⇒ 2(x) - 2(6) + 5 = 20
or, 2x - 12 + 5 = 20
or, 2x = 20 - 5 + 12
⇒ 2 x = 27
or, x = 27/2 = 13.5
⇒ x = 13.5
Hence, the correct explanation of the equation is sated above.
Answer:
2 seconds and 38 seconds
Step-by-step explanation:
h=-16t²-vot
1,200=-16t²-640t
turn this into standard form
16t²-640t+1200=0
now plug thes numbers into the quadratice formula
a 16 b -640 c 1200
solve with quadratic formula to get ≅2 and ≅38 seconds

Answer:
$7.09
Step-by-step explanation:
Let wheat shipment be x bushels
Per bushel cost = 5.35
So x bushels cost = 5.35x
Achieving markup of 6% means 1.06 * 5.35x =5.671x
20% spoiled means 80% of x stays, so 0.8x will need to be sold at 5.671x
Selling price should be 5.671x/0.8x = $7.09
So that's 7 dollars and 9 cents
I believe you combine the first and last terms first because they have the same denominator
