Answer:

A letter (can be mostly any letter) given that has an unknown quantity to it. X is a very common letter to use.

Step-by-step explanation:

For example, 4 + X = 5 (This is just an easy equation to make am explanation more understandable.)

You have to figure out how much x is worth. The answer is 1 because 4 × 1 = 5. Sometimes, you may even see a number multiplying to the variable. Like, 4x=16. When a variable is next to a number like that, that means you are multiplying. 4 times what equals 16? Well, it's 4. So X equals 4.

Tony was Challenged to a half-court shooting competition. For every half-court shot that he makes, he will earn 20 points. For e

Mkey [24]

Answer:

Tony make 4 half-court shots and misses 16 half-court shots.

Step-by-step explanation:

Given:

Points earned for every successful, half-court shots = $20$

Points deducted for missing the shots = $5$ or $-5$

Total number of shots in the game = $20$

Final points earned by Tony = $0$

According to the question:

Let the number of successful half-court shot be $x$

And the number of shots missed be $20-x$

So,

In terms of points we can re-write it as:

⇒ $20(x)-5(20-x) =0$

⇒ $20x-100+5x=0$

⇒ $25x-100=0$

⇒ $25x-100+100=100$

⇒ $25x=100$

⇒ $\frac{25x}{25} =\frac{100}{25}$

⇒ $x=\frac{100}{25}$

⇒ $x=4$

Tony make 'x' shots that is 4 and the number of shot he missed is (20-x) =(20-4)=16

What is the solution to the equation PLS

brilliants [131]

Answer:

x=2.5

Step-by-step explanation:

the first thing you want to do is simplify like terms.

you could say this is as 4(x+7)=38

this can easily be solved algebraically.

first use distributive property on the four

this leaves you with 4x+28=38

next, subtract 28 from both sides

4x=10

now divide everything by four and you get x=2.5
