How many solutions are there for 10(x + 4) – 3 = 14x + 1

Answers

Answer 1

Answer:

X=9

Step-by-step explanation:

Open the bracket first

10(x+4)-3=14x+1

10x+40-3=14x+1

Let's collect like terms

10x-14x=1-40+3

-4x=-36

Let's make x the subject of formula by dividing both sides by-4

X=9

Therefore the final answer for x is 9

Answer 2

Answer: 10(x+4)-3=14x+1
10(4x)-3=14x+1
40x-3=14x+1
37x=14x+1
37x=15x
X=2.5
Or your answer will be 37x=15x

What is the theoretical probability of a coin landing tails up?

Answers

Answer:

The probability that a fair coin lands tail up is 1/2, which is equal to 0.5.

Step-by-step explanation:

There are two possible outcomes when a coin is flipped (saving for the case when the coin lands on its side.)

The coin lands head-up;
The coin lands tail-up.

If the coin is fair, the two outcomes should be equally likely. In that case, apply the following formula:

$\begin{aligned}&\text{Probability that the coin lands tail-up}\n =&\frac{\text{Number of outcomes that the coin lands tail-up}}{\text{Total Number of equally-likely possible outcomes}}\n=&(1)/(2) \n=& 0.5 \end{aligned}$ .

Credit for the phrasing of this probability formula goes to the Khan Academy article "Probability: the basics".

Manny used 8 tenth-size parts to model 8/10. Ana used fewer parts to model an equivalent fraction. How does the size of a part in Ana's model compare to the size of a tenth-size part? Explain.

Answers

Alrighty, let's think of it like this: You are trying to fill a box with a bunch of sports balls. You have tiny little golf balls, and you have giant bowling balls. You need to fill this same box all the way up.

If you fill it with the tiny golf balls, you are going to need a whole lot of them!

If you are putting in bowling balls, only a few of them will fit, because they are so much bigger.

When it comes to your fraction, the box is the the number 8/10. That number will not change because we are not changing the size of the box.

We are just changing what we are filling it with. Manny, can fit 8 parts, or in this case balls, into the box.

It says Ana uses fewer parts, so she cannot fit as many in as Manny.

This means that Manny would have the golf balls, since he can fit more in than Ana, who must have the bowling balls.

So which is bigger? A bowling ball or a golf ball?

A bowling ball, which is what Ana has. So Ana's part will be bigger in size.

Ana's part is bigger
