Answer:
$190.
Step-by-step explanation:
We can write the equation 120=25+1/2n where n is the cost of a new guitar. First, we subtract 25 from both sides to get 95=1/2n. Then, we multiply both sides by 2 to get 190=n. Therefore, the cost of a new guitar is $190.
Answer:
6.7 * 10^7
Step-by-step explanation:
Answer:
a) 8 < 9 < 10 1/2
b) 10 1/2 > 9 > 8
Step-by-step explanation:
We can use inequalities to order shoe sizes. We need to know what the symbols mean, for example < means "is lower than" while > means "is greater than". We know that 8 is lower than 9, and 9 is lower than 10 1/2 (which can be written also as 10.5), so we can write:
a) 8 < 9 < 10 1/2
The other way around would be to say that 10 1/2 is greater than 9, and 9 is greater than 8, which means:
b) 10 1/2 > 9 > 8
