Answer:

x=10

Step-by-step explanation:

20x=200

The first step is to divide both sides by 20. This is because you want x by itself.

20x/20 = 200/20

By doing so, you get x=10.

Hope this helps! Have a great day!

If f(a)=(a•a•a)-(a•a) + a-1 what is the value of f(-3)?

Elena L [17]

Answer:

-40

Step-by-step explanation:

f(a) = a³ - a² + a - 1

f(-3) = (-3)³ - (-3)² + (-3) - 1

f(-3) = (-27) - (9) + (-3) -1

f(-3) = -27 - 9 -3 - 1

f(-3) = -40

Solve 1/2cot(x)>=1/2 over 0<=x<=2pi

RSB [31]

9514 1404 393

Answer:

(0, π/4] ∪ (π, 5π/4]

Step-by-step explanation:

Multiplying by 2 gives ...

cot(x) ≥ 1

The cotangent function decreases from ∞ to 1 in the domain (0, π/4], and again in the domain (π, 5π/4]. The solution is the union of these two intervals.

x ∈ (0, π/4] ∪ (π, 5π/4]

_____

(a, b] is interval notation for a < x ≤ b

The sum of three numbers $x$ ,$y$, $z$ is 165. When the smallest number $x$ is multiplied by 7, the result is $n$. The value $n$

babymother [125]

You're given

x + y + z = 165

7x = n

n = y - 9

n = 9 + z

and you want to find xyz.

Solve the last three equations for x, y, and z :

7x = n → x = n/7

n = y - 9 → y = n + 9

n = 9 + z → z = n - 9

Substitute x, y, and z into the first equation and solve for n :

n/7 + (n + 9) + (n - 9) = 165

n/7 + 2n = 165

n + 14n = 1155

15n = 1155

n = 77

Now solve for x, y, and z :

x = 77/7 = 11

y = 77 + 9 = 86

z = 77 - 9 = 68

Then the product is

xyz = 11 • 86 • 68 = 64,328

A 2-liter container holds more than a 3,000-milliliter container. True or false?

tiny-mole [99]

To consider whether this statement is true or not

⇒ must determine the number of milliliters in a liter

⇒ 1 Liter = 1000 milliliter

To compare both containers, lets set both containers in terms of milliliters

Container 1 --> 2 Liter Capacity --> 2000 milliliter
Container 2 --> 3000 milliliter

By looking at the data

⇒ the 3000-milliliter container holds more than the2-liter container

Thus, the statement: A 2-liter container holds more than a 3,000-milliliter container

⇒ False

Answer: False

Hope that helps!
