Like terms are when the variable you have are the same. In this case it is x. Therefore, when you have like terms, you should add, or subtract your like terms.

(note: When you move one thing to the other side of the equation, make sure to do the opposite of the sign. i.e. if it is +4 when you move to the other side it will be -4).

</span><span>15x+12=45+4x
</span>15x+12-12=45+4x-12
15x=<span>45+4x-12
15x-4x=45+4x-4x-12
15x-4x=45-12
11x = 33
this is the same as:
</span><span>11*x = 33
</span>the opposite of multiply is divide so when we move the 11 it has to be divide
11/11*x=33/11
x=3

<span>15x+12=45+4x </span>⇒15x - 4x = 45 - 12 ⇒ 11x = 33 ⇒ x = 3

Solve the system using substitution.<br> 2x = 5y + 14<br> x = 5y

andrew-mc [135]

Answer:

Step-by-step explanation:

To solve an equation, we can only have one variable. In this case, we are given the system 2x = 5y + 14. However, we are given the value of x in terms of y. We can substitute 10y in for 2x and solve.

10y = 5y + 14

First, we need to get all the variables on one side of the equation, so we subtract 5y.

5y = 14

Divide by 5

y = 14/5 or 2 4/5 or 2.8

Now for the x part.

2x = x + 14

Subtract 1x

x = 14

Now we check our answer.

2(14) = 5(2.8) + 14

28 = 14 + 14

28 = 28

Because 28 equals 28, our solutions are correct.

What is greater 16/25 or 65%

slega [8]

Hi there!

»»————-　★　————-««

I believe your answer is:

65% has the greater value.

»»————-　★　————-««

Here’s why:

We can convert both numbers into decimals and then compare the values.

⸻⸻⸻⸻

$\boxed{\text{Comparing Numbers:}}\\\\-------------\\\rightarrow\frac{16}{25}= 0.64\\\\\rightarrow 65\%=\frac{65}{100}=0.65\\ -------------\\\\\boxed{0.65 > 0.64}\\\\\text{Therefore:}\\\\\boxed{65\% > \frac{16}{25}}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Question 1. 7:11
Question 2. 27 units of K

How to solve the questions-
1. 14/22 divide the numerator and the denominator by 2. This would give you 7/11

2. If the ratio is 12/9 and the amount of N is 36, you’re basically multiplying 12 *3, so then you have to multiply 9 *3=27.
