Fifteen more than half a number is 9

Mathematics
1 answer:
denis-greek [22]4 years ago
4 0
Hey there!

"15 more than" will mean that 15 will be added to another term. The other term is "half a number", meaning 0.5x, where x is the number. This equation is equal to 9. The final equation is 0.5x + 15 = 9. 

To solve this, cancel out the terms until you find what x is equal to:

0.5x + 15 = 9 (subtract 15 from both sides)
0.5x = –6 (divide both sides by 0.5)
x = –12 (final answer)

Hope this helped you out! :-)

Susan tossed a die 1,194 times. Which of the following would be a good estimate of the number of times she got the number 3 on t
denis23 [38]
Assuming this is a fair 6 six sided die she could get a 3 (1/6)th of the time. 1194 x (1/6) = 199 so if she rolled each number the same amount of times it would be 199 times for each number on the die.

From 1980 to 1990 the consumer price index increased from 82.4 to 130.7 if a bottle of dish soap cost 0.74 in 1980 and the price
natta225 [31]

Answer:

$0.43

Step-by-step explanation:

Rate of increase = [(CPI in 1990 / CPI in 1980)^1/t] - 1

(130.7 / 82.4)^1/10

1.586165^0.1 = 1.047213 - 1  = 4.72%

Price of dish soap in 1990 = value in 1980 ( 1 + rate of increase)^10

0.74( 1.047213)^10 = 1.174

Price increase 1.174 - 0.74 = 0.43
