What is 5x-9 > 11 i need the whole anderr

Feliz [49]

Answer:

x ≥ 4

Step-by-step explanation:

Start with: 5x - 9 ≥ 11

Add 9 to both sides: 5x - 9 + 9 ≥ 11 + 9

Divide both sides by 5: $\frac{5x}{5} \geq \frac{20}{5}$

Simplify: x ≥ 4

Since you are not dividing both sides by a negative number, the greater than or equal to sign faces the same direction.

Answer:

9.85

Step-by-step explanation:

you can use the Pythagoras theorem

$a^2+b^2=c^2$

with c the hypotenuse

$9^2+4^2=c^2\\\\81+16=c^2\\\\97=c^2\\\\c=\sqrt{97}$

which is aprox

The numeric value of the expression d² + 3a + 6 + a when a = 2 and d = 5 is of 39.

<h3>How to find the numeric value of an expression?</h3>

The numeric value of a function is found replacing each instance of a variable by the value of the input for which we want to find the numeric value.

For this problem, the expression is given by:

d² + 3a + 6 + a

We want to find the numeric value when a = 2 and d = 5, hence:

5² + 3(2) + 6 + 2 = 25 + 6 + 6 + 2 = 39.

An art classroom has 5 boxes with sharpie pens and clipboards. Each box has 4 sharpies there are 25 supplies in all how many tot

Step2247 [10]

Answer:

1 clipboard per box

Step-by-step explanation:

First, multiply 4 by 5 (because we need to see how many supplies there are already taken up)

4x5= 20

Next, subtract 25 from 20 (to see how many total clipboards there are)

25-20= 5

Since there are 5 boxes, we divide the number of clipboards(5) by the number boxes(5):

5/5= 1

Jaclyn estimates the square root of 50 in the following way:

OLga [1]

<h2>Hello!</h2>

The answer is:

a) Her reasoning is incorrect, she applied a wrong operation, the way to simplify the expression was using the square root property. If we want to extract a number of a square root, we must square that number first in order not to modify the expression.

b) We have that:

$\sqrt{200}=14.14$

and rounding to the nearest tenth, we have that:

$\sqrt{200}=14.1$

To solve the problem, we need to remember the following property of square roots:

$\sqrt{ab}=\sqrt{a}*\sqrt{b}$

We are given the expression:

$\sqrt{200}$

We can rewrite it by the following way:

$\sqrt{100*2}$

Now, applying the square root property we have:

$\sqrt{100*2}=\sqrt{100}*\sqrt{2}=10\sqrt{2}=14.14$

Therefore,

a) Her reasoning was wrong, she applied a wrong operation, the way to simplify the expression was using the square root property. If we want to extract a number of a square root, we must square that number first in order not to modify the expression.

b) We have that:

$\sqrt{200}=14.14$

and rounding to the nearest tenth, we have that:

$\sqrt{200}=14.1$

Have a nice day!
