Answer:
- Any of x = {-3, 5, -1, 0}
Step-by-step explanation:
Since the relationship in the table is not a function, Rae could put any values for x that is already in the table.
This will result in repeat of x-values with different corresponding y-values.
Answer:
12 sapphires
Step-by-step explanation:
Let's call the number of sapphires x. This means the number of rubies is the total number of gems minus x, or 17-x.
# of Sapphires: x
# of Rubies:17-x
A sapphire is worth 5 (gold coins) each, and a ruby is worth 8.
We also know the total amount of money is 100 coins, so
5*x+8*(17-x)=100
5x+136-8x=100
-3x=-36
x=12
Remember:
# of Sapphires: x
# of Rubies:17-x
...so Lara found 12 sapphires and 17-12=5 rubies.
Hi!
First, you have to add the addition equation.
(4 + 12) = 4 + 12 = 16
Now, the equation will look like this:
2.3 x 16
Now, you just take this equation like normal:
2.3 x 16 = 36.8
