These 2 questions please! Give explanation! Big points

1. So Chris has 10c coins and 20c coins and they're the same amount, I'll ignore the c for the calculations but keep in mind that these are cents.

Let x be the number of coins

10x = 20x

And well the 20 cents come to 60 cents more than the 10 cent coins which means the total amount given by the number of coins of 20 cents is 60 cents more ( + 60) than the amount given by the number of coins of 10 cents. Thus,

20x = 10x + 60

x = 6

So, 6 x 0.10 = 0.60$ and 6 x 0.20 = 1.20$

0.60$ + 1.20$ = 1.80$

2. Michael has 4 coins of 5 cents so, and 4 20 cents coins, 5 50 cents coins, one 10 cents coin.

We don't wanna use the 50 cents they would quickly reach the max number.

We want to use the smallest amounts of coins definitely, so

0.10(1) + 0.5(2) + 0.20(4) = 1$

So pretty much 7.

I didn't use 4 times the 0.5 because that would leave a gap of 0.10$ that can't be covered by any other coin so I replaced the 0.10$ and two of the 0.5$ coins by a single 0.20$ coin.

they will manufacture 8496 cars

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest
