Answer:
-0.00961
Step-by-step explanation:
1/5 probability of spinning a red. 1/6 probability of rolling a four.
Explanation:
There is only one red and one four on the dice. After you find how many there are of each thing, just count how many sides there are and turn that into a fraction.
Let the number be x.
(2/3)x = 3 1/2 + (3/8)x
(2/3)x - (3/8)x = 3 1/2
(8*2 - 3*3)/(8*3) x = 7/2
(16 - 9)/24 x = 7/2
(7/24)x = 7/2
7x/24 = 7/2 Divide both sides by 7
x/24 = 1/2
x = 24*1/2
x = 12
The number is 12.
Answer:
Equation for cost of the hall restoration fee 70.4 + 52.8 + 11f = 128 .15 and the cost of the hall restoration fee is $0.45 .
Step-by-step explanation:
Let us assume that the hall restoration fee be f .
As given
The ticket price for a concert at a historic music hall includes.
$6.40 for the concert $4.80 for the program and a hall restoration fee the price for 11 tickets is$128.15 .
Than the equation becomes
(Cost for concert + Cost for program + Hall restoration fee) × Number of tickets = Total amount of 11 tickets
Putting all the values in the above
(6.40 + 4.80 + f) × 11 = 128.15
Open the bracket
6.40 × 11 + 4.80 × 11 + 11f = 128.15
70.4 + 52.8 + 11f = 128 .15
11f = 128 .15 - 123.2
11f = 4.95
f = $ 0.45
Therefore the equation for cost of the hall restoration fee 70.4 + 52.8 + 11f = 128 .15 and the cost of the hall restoration fee is $0.45 .
Answer: the answer is D.
x/-2 - 17 = -7 (subtract both sides by -17)
x/-2 = 10 (multiply both sides by -2)
x = -20
