Hannah is making calzones to sell her restaurant she starts with nine cans of tomato sauce and then use is 9/10 of the cans for
Mademuasel [1]

Answer:

About 8 cans.

Step-by-step explanation:

Given:

She starts with nine cans of tomato sauce.

Then use is 9/10 of the cans for her first batch of calzones

To find:

How many cans of tomato sauce does Hannah use for the first batch of calzones ?

Solution:

She starts with number of cans = 9

Then use is \frac{9}{10} of the cans.

Now, we will find number of cans used for the first batch of calzones by multiplying number of cans she starts with by fraction of  cans she used  for the first batch of calzones .

\frac{9}{10} of 9  cans = \frac{9}{10} \times9\\\frac{81}{10} = 8.1

Therefore,  number of cans used for the first batch of calzones is about 8 cans.

2. √2x-5-√x+6=0(solving the following radical equations and check for extraneous solutions)
Norma-Jean [14]

I assume the equation is

√(2x - 5) - √(x + 6) = 0

Note the domains for the root expressions:

• √(2x - 5) : 2x - 5 ≥ 0   ⇒   x ≥ 5/2

• √(x + 6) : x + 6 ≥ 0   ⇒   x ≥ -6

So any valid solution we find must be at least 5/2.

Move one term to the other side.

√(2x - 5) = √(x + 6)

Take squares.

(√(2x - 5))² = (√(x + 6))²

2x - 5 = x + 6

Solve for x :

x = 11
