Answer:
x = 1
Step-by-step explanation:
Given
12x + 3 = 15x ( subtract 12x from both sides )
3 = 3x ( divide both sides by 3 )
1 = x
She has $55. She spent $22.50 on rides so now she has $32.50 . Then she spends $14.25 on lunch and snack so now she has $18.25.
A. would be wrong because Courtney IS correct, she has $18.25 left.
C. is also wrong because, again, Courtney IS correct.
So the only option left is B and it explains why Courtney is correct.
Option B is the correct answer.
Hope this helps.
Answer:
60,000
Step-by-step explanation:
Let the total people in the household be 100%
If 80 percent of the households have cable television, 60 percent of the households have videocassette recorders and the number of households that have both cable television and videocassette recorders is 'x' percent. The number of households having ONLY cable television will be 80-x while households having ONLY videocassette will be 60-x.
To get x, we will have;
80-x + 60-x + x = 100
140-x = 100
x = 140-100
x = 40
This shows that 40% of the households have both cable television and videocassette.
If there are 150,000 households in the city, then the number of households that have both cable television and videocassette recorders could be 40% of 150,000
= 40/100 × 150,000
= 60,000
Number of households that owns both television and videocassette could be from 60,000.
Answer:
D
Step-by-step explanation:
x^2 - 7x + 12 + (x - 3)^2 Add (x - 3)^2 after it has been expanded.
x^2 - 7x + 12 + x^2 - 6x + 9 Combine like terms
2x^2 -7x - 6x + 21
2x^2 - 13x + 21 Factor
(2x - 7)(x - 3)
Which is exactly what D says.
Keeping in mind that, an absolute value, is in effect a piece-wise function, so is a duplet, so |whatever here| is really two siblings, the positive and negative siblings +(whatever here) and -(whatever here), thus
