3(x + 2) = 12


Please help it’s urgent!!

Answers

Answer 1

Answer:

3(x+2)=12

Step-by-step explanation:

Ok, so this is simple. First you multiply the three on the outside by the x and 2 on the inside using the distributive property. Then you should get 3x (3 times x) + 6 (3 times 2). now that you have 3x+6=12, you can subtract the 6 from both sides. you should end up with 3x=6. To figure out x you should divide both sides by 3. You should end with x = 2.

3(x+2)=12

3x+6=12

3x=6

x=2

Step-by-step explanation:

Given

-5x-8=8

Add 8 on both sides

-5x-8+8=8+8

-5x=16

Divide -5 on both sides

-5x/-5=16/-5

x=-3.2

Therefore, it has one solution

​

Answers

Answer: m<C = 40

Step-by-step explanation:

Triangle angle sum theorem states that the interior angles of a triangle sum to 180. We have two angles 90 and 50. Now we need to find the third. 90+ 50 +<C = 180. 140+ C = 180. C = 40

Answer:

40

Step-by-step explanation:

sum of angle in a triangle is 180

180=90+50+c

180=140+c

180-140=c

40=c

c=40°

which number should each side of the equation 2/3 x = 10 be multiplied by to produce the equivalent w
equation of x = 15

○-2/3

○1/3

○3/2

○3​

Answers

The answer is 3/2.
Explanation: you want to get x by itself so that you have the equation x = 15. To do that you multiply 2/3x * 3/2 to get x. this works because 3/2 cancels out 2/3 and you get 1. Multiplying 10 by 3/2 also gets you 15. So in the end you have
x = 15.

I dont get this I need help to find the answer: 2x + 4 = -6x - 12

Answers

Answer:

x= -2

Step-by-step explanation:

2x + 4 = -6x - 12

(-4 from both sides)

2x=-6x-16

(add 6x to both sides)

8x=-16

divide by 8

x=-2

Okie, let’s do this mate!

1. Bring the variables to one side. But remember the sign of the number would change if the number is brought on the other side of the equal sign.

2x + 6x = -12 - 4


2. Now that you have the equation nice and organized add the variables add the constants (regular numbers) together!

8x = -16


3. You are almost done! Now divide each side by 8 since both of the numbers on either side of the equal sign can be divisible by 8.

x = -2

So your solution to your problem would be x = -2



Hope this helped have an awesome day!

Step-by-step explanation:

The nth term of a sequence is 3n²-1

The nth term of a different sequence is 30–n²

Find the only number that is in both of these sequences.

Answers

Answer: The number is 26.

Step-by-step explanation:

We know that:

The nth term of a sequence is 3n²-1

The nth term of a different sequence is 30–n²

We want to find a number that belongs to both sequences (it is not necessarily for the same value of n) then we can use n in one term (first one), and m in the other (second one), such that n and m must be integer numbers.

we get:

3n²- 1 =  30–m²

Notice that as n increases, the terms of the first sequence also increase.

And as n increases, the terms of the second sequence decrease.

One way to solve this, is to give different values to m (m = 1, m = 2, etc) and see if we can find an integer value for n.

if m = 1, then:

3n²- 1 =  30–1²

3n²- 1 = 29

3n² = 30

n² = 30/3 = 10

n² = 10

There is no integer n such that n² = 10

now let's try with m = 2, then:

3n²- 1 =  30–2² = 30 - 4

3n²- 1 = 26

3n² = 26 + 1 = 27

n² = 27/3 = 9

n² = 9

n = √9 = 3

So here we have m = 2, and n = 3, both integers as we wanted, so we just found the term that belongs to both sequences.

the number is:

3*(3)² - 1 = 26

30 - 2² = 26

The number that belongs to both sequences is 26.

Nicole practices the piano 1008 minutes in 4 weeks. If t represents the total time she practices for any number of days, d, write a proportional equation for t in terms of d that matches the context

Answers

It is t = 36d.

That’s because d represents the total time she practices for a number of days, therefore we would want to find how many minutes she spends per day practicing. 4 weeks is 28 days, so you do 1008 minutes divided by 28 days to get 36 minutes a day. Hope this helps
