Solve for n by simplifying both sides of the equation, then isolating the variable:
N + (n + 2) + (n + 4) = 42
N = 12
Answer:
$70
Step-by-step explanation:
essentially, Judy paid 90% of the original price
therefore you can write this equation where 'x' equals the original price:
.9x = 63
x = 63/.9
x = 70
It's a similar triangle so the ratios of corresponding sides should be equal which means
BC/EF = AB/DE
21/14 = AB/10
AB = 21/14 * 10 = 15 cm
