Answer: x = -1 and y = -2
Step-by-step explanation:
You are given two expressions that have a relationship. There are two ways to solve this problem, but I will be going over the easy way. I'm assuming you know how to solve for one variable such as x? Well we can put the y varaible from the first equation in terms of x, from the second equation. Ill show you what I mean:
6x + 5(7x + 5) = -16
I replaced y in the first one in terms of x, so that we can solve just for x.
6x + 35x + 25 = -16
41x +25 = -16
41x = -41
x = -1
Now simply find y by plugging the now known x value into either equation
y = 7(-1) + 5
y = -2
First write 24000 in word form.
Then take the whole number witch would be 24 and count the zeros.
There are three zeros so put 10 and put 3 on top.
Then put it together.
Twenty-Four thousand
Twenty-Four
000

The answer:
Twenty-Four x

Hope this helps
Two equations that have the same solution are called equivalent equations e.g. 5 +3 = 2 + 6. And this as we learned in a previous section is shown by the equality sign =. An inverse operation are two operations that undo each other e.g. addition and subtraction or multiplication and division. You can perform the same inverse operation on each side of an equivalent equation without changing the equality
Sum of <span>supplementary = 180
180 - 35 = 145
145/2 = 72.5
so
one angle = 72.5
and
its supplement = 72.5 + 35 = 107.5

Answer:
Though it may vary, it's going closer to 0.5 as long as we enlarge our sample.
Step-by-step explanation:
1) Since a coin has heads and tails, then a sample proportion of 40 we can simulate it using some applets.
2) Here are the most common outcomes, as long as we continue on flipping coins.

If we continue enlarging our sample (80, 120,160...) the probability goes closer to 0.5
This shows: the theoretical probability goes closer and closer to the experimental probability of heads and tails
