Answer:
The inequality for amount x (in dollars) is given by
x ≤ $33 - (cost of necklace).
Step-by-step explanation:
Let the cost of the necklace be $ y.
The amount for the necklace is constant and it is less than $33 and it is also known that the amount for the necklace will be spent.
Therefore after the necklace has been purchased and the amount deducted from $33 the remaining amount can be used completely or partly to purchase the other item.
Let the cost in dollars of the other item be $x.
The inequality for amount x (in dollars) is given by
x ≤ $33 - (cost of necklace)
Answer:
see below
Step-by-step explanation:
f(x) = –(x + 6)(x + 2)
The function is increasing until it reaches the vertex, so it will increase until x=-4. The function will decrease after the vertex, so after x = -4
increasing: -∞ < x < -4
decreasing : -4 < x < ∞
The error of percentage is the amount of error over the original amount.
In this case it is 22/95 (not 22 over 77 because 77 is not the original amount they expected to sell.
22/95 = .2315 or 23.2% to the nearest tenth of a percent
Perhaps your teacher just wants 23% as an the approximate error.
Answer:
Step-by-step explanation:
The proportion that Alan solved was
x/200 = 8/25
His working as shown was
(8)(x) = (25) (200)
8x = 5000
He divided both sides of the equation by 8. It became
8x/8 = 5000/8
x = 625
The correct steps are
25x = 200 × 8 = 1600
Dividing both sides of the equation by 25, it becomes
x = 1600/25
x = 64
Alan's error were:
1) He got the wrong product when he multiplied 25 by 200.
2)He got the wrong quotient when he divided 5,000 by 8.
