What's the value of 28 tens

Answers

Answer 1

Answer: The value of 28 tens is 280 because a ten is literally 10 you only multiply 28*10= 280 So the value of 28 tens is 280.

Thank You!

Answer 2

Answer: the value will be 280 because you have 28 tens and you will have to do 28*10 to get the answer

remember you can do ANYTHING to an eqyation as long as you do it to BOTH SIDES (except divide by zero)

tr to isolate the unknown by itself

3x+3=12
minus 3 both sides
3x+3-3=12-3
3x+0=9
3x=9
divide by 3
x=3

x/4+4=8
minus 4
x/4=4
multiply 4
x=16

3x + 3 = 12

To solve these type of equations, we need to apply the inverse operation to both sides of the equation. Next, we'd isolate the variable.

Here's how it's done:

3x + 3 = 12
- 3 -3

Notice, we subtracted 3 from both sides.

3x = 9
3x/3 = 9/3
x = 3

Now for the other:
x/4+4=8
- 4 -4

8 - 4 = 4

x/4 = 4
x/4 * 4/1 = 4 * 4
x = 16

We're officially done:

1st one: x = 3
2nd one: x = 16

Answer:

$h^(- 1) (x) = \sqrt{(x - 8)^(3)} = (√(x - 8))^(3) = (x - 8)^{(3)/(2) }$

Step-by-step explanation:

The given function is $h(x) = \sqrt[3]{x^(2)} + 8$ and we have to find the inverse function of this function h(x).

Now, let us assume, $y = \sqrt[3]{x^(2)} + 8$

⇒ $y - 8 = \sqrt[3]{x^(2)}$

⇒ $(y - 8)^(3) = x^(2)$ {Cubing both sides}

⇒ x² = (y - 8)³

⇒ $x = \sqrt{(y - 8)^(3) }$

Therefore, the inverse function $h^(- 1) (x) = \sqrt{(x - 8)^(3)} = (√(x - 8))^(3) = (x - 8)^{(3)/(2) }$

So, options A, B, and D are correct. (Answer)

–0.8b2+7.4b+(5.6b–0.2b2)

Answers

In this question, you would be combining like terms

Solve by combining like terms:

-0.8b²+7.4b+(5.6b-0.2b²)

This is the same as:

-0.8b² + 7.4b + 5.6b - 0.2b²

Solve:

-0.8b² + 7.4b + 5.6b - 0.2b²

-1b² + 7.4b + 5.6b

-1b² + 13b

Answer:

-1b² + 13b

Answer:
