Answer:

Step-by-step explanation:

Simplifying

W + -2 + 2w = 6 + 5w

Reorder the terms:

-2 + W + 2w = 6 + 5w

Solving

-2 + W + 2w = 6 + 5w

Solving for variable 'W'.

Move all terms containing W to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + W + 2 + 2w = 6 + 2 + 5w

Reorder the terms:

-2 + 2 + W + 2w = 6 + 2 + 5w

Combine like terms: -2 + 2 = 0

0 + W + 2w = 6 + 2 + 5w

W + 2w = 6 + 2 + 5w

Combine like terms: 6 + 2 = 8

W + 2w = 8 + 5w

Add '-2w' to each side of the equation.

W + 2w + -2w = 8 + 5w + -2w

Combine like terms: 2w + -2w = 0

W + 0 = 8 + 5w + -2w

W = 8 + 5w + -2w

Combine like terms: 5w + -2w = 3w

W = 8 + 3w

Simplifying

W = 8 + 3w

W=-4
start by subtracting 2w from both sides
then subtract the single w on the left, getting -2=6+2w
next, subtract the 6 from both sides and you get -8=2w
then, just decide both sides by 2 and you get -4=w

12.1.33 Question Help Suppose that 62% of families living in a certain country own an HDTV and 16% own a computer. The Additio

poizon [28]

Answer:

Step-by-step explanation:

Suppose :

62% own an HDTV

16% own a computer

Using the addition rule : suggests that (62% + 16%) = 78% either own an HDTV or a computer.

The reasoning is wrong because ; since it is possible to own both an HDTV and also own a computer at the same time, the outcome of the addition rule is wrong as both events are independent. If both event cannot occur at the same time (mutually exclusive event) , then, the addition rule may be applied,. But since both can occur independently and each family can own an HDTV while also owning a computer, then the addition rule is wrong for the scenario described.

Evaluate [5 - (5 - 5(2 - 5) + 2)] + 6

Otrada [13]

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

Evaluate [5 - (5 - 5(2 - 5) + 2)] + 6

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$\sf [5 - (5 - 5(2 - 5) + 2)] + 6$

Subtract 5 from 2 to get -3.

$\sf \: 5-\left(5-5\left(-3\right)+2\right)+6$

Multiply 5 and -3 to get -15.

$\sf \: 5-\left(5-\left(-15\right)+2\right)+6$

The opposite of -15 is 15.

$\sf \: 5-\left(5+15+2\right)+6$

Add 5 and 15 to get 20.

$\sf \: 5-\left(20+2\right)+6$

Add 20 and 2 to get 22.

$\sf \: 5-22+6$

Subtract 22 from 5 to get -17.

$\sf \: -17+6$

Add -17 and 6 to get -11.

$= \boxed{ \boxed { \bf \: - 11}}$

Terry is filling spherical water balloons with a faucet that puts out 100 cm 3 100 cm 3 100, start text, space, c, m, end text,

Juli2301 [7.4K]

Correct question is;

Terry is filling spherical water balloons with a faucet that puts out 100 cm³ of water per second. At that rate, it takes Terry 6 seconds to fill a balloon. What is the radius of a filled balloon?

Answer:

r = 5 cm

Step-by-step explanation:

Volume of a sphere is;

V = (4/3)πr³

It takes 6 seconds to fill the balloon when a faucet that puts out 100 cm³ of water per second.

Thus,

Volume of balloon = 100 × 6 = 600 cm³

Thus;

(4/3)πr³ = 600

r³ = (600 × 3)/4π

r³ = 143.239

r = ∛143.239

r = 5.23

Approximation to the nearest whole number gives; r = 5 cm
