Answer:
Yeah I feel you on that one my guy
Step-by-step explanation: I dont know either
10^8=100000000
100000000x6.71=671,000,000
60/6000 = x/1423
100/1 = 1423/x
100x = 1423
x = 14.23 --> About 14 cm
Solve the second equation for y so that you can substitute it in for y in the first equation..
y = 5x - 4
Substitute:
3x + (5x - 4) = 1
Not sure what answer your needing so here is a breakdown of the amounts.
3 bracelets times $5 equals $15
How much is each necklace?
Subtract $15 from $40 you have $25 left. Then you divide $25 by 3 you get each necklace costs $8.33 so three necklaces cost $24.99
When you add $15 from the bracelets and $24.99 from the necklaces your total is $39.99 that’s why Megan gave the clerk $40
Hope this helps
