Answer:
x = .
Step-by-step explanation:
Given : 11.42424242 …
To find : Convert it to a rational expression in the form of a over b, where b ≠ 0.
Solution: We have given 11.42424242 …
We can see here two number 42 are repeating.
Let x = 11.42424242 …
On multiplying both sides by 100
100x = 100 * 11.42424242 …
100x = 1142.424242.....
100x = 11.4242.....+1131.00000.....
100x = x + 1131.0000....
On subtracting both sides by x
100x -x = 1131
99x = 1131.
On dividing both side by99.
x = .
Therefore, x = .
The cost of one doughnut is $0.75 and the cost of one cookie is $0.60.
The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Alexandra buys two doughnuts and three treats at a donut shop and is charged $3.30. Brianna buys five doughnuts and two treats at a similar shop for $4.95. Every one of the doughnuts and treats has a similar cost.
Assume 'x' is the cost of doughnuts and 'y' is the cost of one cookie. Then the equations are given as,
2x + 3y = 3.30 ...1
5x + 2y = 4.95 ...2
Multiply equation 1 by 5 and equation 2 by 2, then we have
10x + 15y = 16.50 ...3
10x + 4y = 9.90 ...4
Subtraction equation 2 from equation 1, then we have
15y - 4y = 16.50 - 9.90
11y = 6.60
y = $0.60
Then the value of 'x' is given as,
2x + 3(0.60) = 3.30
2x + 1.80 = 3.30
2x = $1.50
x = $0.75
The expense of one donut is $0.75 and the expense of one treat is $0.60.
