4 times 2 1/2 tons is 10 tons per week!

Since there are 4 elephants, they would eat 2 1/2 tons multiplied by 4 each week.

So. Change 2 1/2 to an improper fraction. 5/2

Then multiply 5/2 by 4/1.

20/2

Then simplify.

10 tons a week is your answer.

Answer: 46

Step-by-step explanation:

Given : Margin of error : E= 17

Standard deviation : $\sigma=70$

Critical value for 90% confidence level : $z_{\alpha/2}=1.645$

Formula to find sample size is given by :-

$n=(\dfrac{z_{\alpha/2}\times \sigma}{E})^2$

i.e. $n=(\dfrac{(1.645)\times 70}{17})^2$

$\Rightarrow\ n=45.880700692\approx46$

Hence, the required minimum sample size = 46.

Use the distributive property to write the next step in simplifying the equation. Use the asterisk symbol (*) to represent multi

Maksim231197 [3]

Given:

The equation is:

$x(4+5)=54$

To find:

The next step in simplifying the equation by using distributive property.

Solution:

Distributive property: According to this property if a, b and c are three real numbers, then

$a(b+c)=ab+ac$

We have,

$x(4+5)=54$

Using the distributive property, we get

$x(4)+x(5)=54$

It can be written as:

$4x+5x=54$

Therefore, the next step of the simplification is $4x+5x=54$ .

HACTEHA [7]

Answer:

Option 1 - X = 9

Step-by-step explanation:

The solution to this equation, x - 15 = - 6

Solving the following,

Step 1: x - 15 = -6

Replace all the numerical values in one side and x digits on the other side

Step 2: x = -6+15

Step 3: x = 9

Therefore, the value of x is 9.
