Variables are the letters in the equation (like x and y)

Coefficients are the numbers before the variables. (like "6" in "6x")

Constants are the actual numbers (like "2" or "1")

Factors: Numbers that are multiplied together (like "5" and "6" in 5 * 6)

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!

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

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.

The current value of a card is 60 times the original price in dollars the baseball card is worth $15 right in solving equations to find the original value of baseball card

Answers

Answer:

i think the answer is 4

Step-by-step explanation:

i'm sorry if it isn't right i'm not the smartest person in the world

Answer:

$0.25

Step-by-step explanation:

If the baseball card is worth 60 times as much as before, and it's worth $15 right now, then:

$15 = 60x

This means that 60 times the original price x is $15.

The original price would be:

$15 = 60x

0.25 = x

x = $0.25

if you have a triangle with a=90 , angle b=50 , find angle c
​

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°
