Answer:
1/3
Step-by-step explanation:
differentiate first equation to get t , then replace t with 1/3
The answer is c because 2+7=9 and 10-2=8 and 9 is greater than 8 so 2+7>10-2
Answer: a loss of 4 cents
<u>Step-by-step explanation:</u>
The probability of rolling a sum of 2, 3, 4, 5, or 6 is
which earns $2.00
The probability of rolling a sum of 28, 9, 10, 11, or 12 is
which loses $2.00
The probability of rolling a sum of 7 is
which loses $0.25

Answer:
w=67°
Step-by-step explanation:
First you solve for x. 12x+11=x. X would be 1. Then you plug in 1 for x and add the w to the equation. 12(1)+11+w=90. after solving that you will get the total for w. which should be 67°
To start, first distribute the x's to their expressions. This would look like this:
(x*x+2*x)+(x*x+x*3)=x^2+2x+x^2+3x
Then, you combine like terms or simplify, and you get an answer of 2x^2+5x
