What is the value of x in the equation is 4+6x=-3+7x​

Mathematics
1 answer:
Anvisha [2.4K]3 years ago
5 0

Answer:

x=1

Step-by-step explanation:

  1. choose a side to get rid of so since its easier to take 6 away from seven we will do that but remember what you do to one side you have to do to the other
  2. so take away 6x from the left that leaves 0 your equation should look like this 4=-3+7x remember that we have to to it to the right side too
  3. so take 6x away from the 7x on the right side and that leaves 1x so it should look like this 4=-3+1x
  4. then since it's a -3 you will need to add 3 for it ton equal 0 so it will look like this 4=7x
  5. but dont for get to do the same to the other side so add 3 to the 4 on the left so it will look like this 7=7x
  6. then divide by 7 to get x by itself so it will look like this 7=x
  7. but you aren't done yet you still have to divide the left by 7 so it will look like this 1=x

and thats all there is to it hope this helps

Marvin used a customary unit of measure to estimate the weight of a watermelon he grew in his backyard what could the estimated
Andrej [43]

Answer:

Usually pounds (lb) .About an an average of  20 to 25 pounds (lbs)

Step-by-step explanation:

Since Marvin uses Customary units, and considering the Watermelon.

Pounds,  He could estimate based on average of 20 to 25 pounds.

He could choose another customary units, but it wouldn't be practical and unusual to say a watermelon of 160 quarters, also it would leave all the listeners without parameters.

So, definitely pounds.

I need help with this problem
Arada [10]

Answer:

65.56°

Step-by-step explanation:

We know that if we take dot product of two vectors then it is equal to the product of magnitudes of the vectors and cosine of the angle between them

That is let p and q be any two vectors and A be the angle between them

So, p·q=|p|*|q|*cosA

⇒cosA=\frac{u.v}{|u||v|}

Given u=-8i-3j and v=-8i+8j

|u|=\sqrt{(-8)^{2}+ (-3)^{2}} =8.544

|v|=\sqrt{(-8)^{2}+ (8)^{2}} =11.3137

let A be angle before u and v

therefore, cosA=\frac{u.v}{|u||v|}=\frac{(-8)*(-8)+(-3)*(8)}{8.544*11.3137} =\frac{40}{96.664}

⇒A=arccos(\frac{40}{96.664} )=arccos(0.4138 )=65.56

Therefore angle between u and v is 65.56°
