(x/6) + 4 = 15
-4 -4
x/6 = 11
x6 . x6
x=66
Answer:
Noah's expression is wrong because he used the wrong coefficients for the variables, and he used a subtraction sign instead of an addition sign.
The correct expression is 2m + 10c
Step-by-step explanation:
Noah is incorrect because he used the wrong coefficients for both of the variables in the expression.
Since muffins are $2 each, and m is the number of muffins, the amount of money made from the muffins is 2m, not 10m.
Similarly, since cakes are $10 each, and c is the number of cakes, the amount of money made from the cakes is 10c, not 2c.
Noah is also incorrect because he used a subtraction sign instead of an addition sign. The amounts made from the muffins and cakes have to be added together.
Putting all of this together, the correct expression is 2m + 10c.
Answer:
A. 75.36 in^3
Step-by-step explanation:
r =3 in
h=8 in
v=1/3 π r^2h
= 1/3×3.14×3×8
=75.36 in^2
hope it helps...
have a great day!!
The answer is 80 cents. How did I get this?
Fair price of a ticket means this raffle will make no profit, the expected value is zero. The people holding to raffle will not lose nor make any money. The only winners would be the people who purchased the tickets.
1. To find the fair price you have to multiply the price of the prize by the probability:
Probability of winning = 1/1000 (because that's how many tickets were sold)
Cost of prize = $200
$200 x 1/1000 = .20
2. Subtract the cost of the ticket from the answer from #1
$1-.20 = .80
80 cent is the cost of a fair price ticket.
Answer:
B. x = k +c / 4
Step-by-step explanation:
4x- c= k
4x=k+c
x=k+c/4
