5+4i+3-2i= 8+2i
the answer to the question
Answer:
Step-by-step explanation:
1) Let x represent the sale price.
normal price = $39.95. This week they are on sale for 25% off the regular price. The amount taken off is
25/100 × 39.95 = 9.9875
Sale price = 39.95 - 9.9875 = $29.9625
2) number of games played by the tigers is 11 + 4 = 15
Percentage of games won is
11/15 × 100 = 73.3%
number of games played by the cubs is 10 + 3 = 13
Percentage of games won is
10/13 × 100 = 76.9%
3) increase in stock price = 61.5 - 52.63 = $8.87
Percentage increase = 8.87/52.63 × 100 = 16.85%
4) if 28 percent of seven graders went
to a movie theater over the weekend and there are 800 students in the seventh grade, then the number of seven graders that saw
the movie is
28/100 × 800 = 224
5x+20=445
The 5x represents you and your four friends because there’s a total of 5 of you the 20 represents what you paid for parking and the 445 is the total if you solve it you’ll get what you paid for each person
Answer:
The car will be worth £2516.22 in 5 years
Step-by-step explanation:
The rule of depreciating is
, where
- <em>A</em> is the new value
- <em>P</em> is the original value
- <em>r</em> is the rate in decimal
- <em>t</em> is the time in years
∵ Dan buys a car for £2700
∴ <em>P</em> = 2700
∵ It depreciates at a rate of 1.4% per year
∴ <em>r</em> = 1.4% = 1.4/100 = 0.014
∵ We need to find how much it will be worth in 5 years
∴ <em>t</em> = 5
→ Substitute all of these values in the rule above to find A
∵ 
→ Use your calculator to find the answer
∴ <em>A</em> = 2516.22
∴ The car will be worth £2516.22 in 5 years
Answer: the selling price of the television at store B is $1360
Step-by-step explanation:
Assuming the selling price of the television at store B is represented by $B. Store A is selling the television for $800, which is $120 more than half the cost of the television at store B. The equation representing this situation is expressed as
800 = B/2 + 120
Multiplying the left hand side and the right hand side of the equation by 2, it becomes
1600 = B + 240
B = 1600 - 240
B = $1360
