What is 12+5x=2x-9 step by step

Mathematics
1 answer:
Alja [10]2 years ago
6 0

Answer:

  x = -7

How to:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation

5°x-(2°x-9)=0

Pull out like factors:

21 + 3x  =   3 • (x + 7)

Equations which are never true:  Solve 3   =  0

<em>Solving a Single Variable Equation:</em>

Solve  :    x+7 = 0

Subtract  7  from both sides of the equation : x = -7

Molodets [167]

Answer:

b. type II

Step-by-step explanation:

given that food inspectors  inspect samples of food products to see if they are safe. This can be thought of as a hypothesis test with the following hypotheses.

H0: the food is safe

Ha: the food is not safe

It was concluded from the hypothesis test that the food is safe while it was not actually safe.

This is a case of false acceptance of null hypothesis when it is false.

In hypothesis test, there are two errors. a type I error is the rejection of a true null hypothesis  while a type II error is the non-rejection of a false null hypothesis

So this is type II error because we did not reject a false null hypothesis.

ss7ja [257]

Answer:

144 in²

Step-by-step explanation:

Find the area of the larger square, then subtract the area of the square we cut out.

The larger square has side length of 15, so it has an area of 15² = 225 in²

The smaller square has side length of 9, so it has an area of 9² = 81 in²

The area left over is

225 - 81 = 144 in²
