(219,379.01 - x) / x = .3321

Answers

Answer:x = 164686.592598

Step-by-step explanation:

219379.01−x/x = 0.3321

−x+219379.01/x = 0.3321

Step 1: Multiply both sides by x.

−x+219379.01≈0.3321x

−x+219379.01 − 0.3321x = 0.3321x−0.3321x (Subtract 0.3321x from both sides)

−1.3321x + 219379.01 = 0

−1.3321x + 219379.01 − 219379.01 = 0 − 219379.01 (Subtract 219379.01 from both sides)

−1.3321x = −219379.01

−1.3321x/−1.3321 = −219379.01/−1.3321

(Divide both sides by -1.3321)

x = 164686.592598

Answer:

164,686.59

Step-by-step explanation:

Carry out the division, then solve for x.

(219,379.01 - x) / x = .3321 . . . . . given

219,379.01/x -1 = 0.3321

219,379.01/x = 1.3321 . . . . add 1

219,379.01/1.3321 = x ≈ 164,686.59 . . . . multiply by x/1.3321

Rounded to 8 significant digits, the value of x is 164,686.59.

- 1/9x+2.4=6 what is x

Answers

First we’re going to subtract 2.4 from both sides
-1/9x+2.4-2.4=6-2.4
Then we’re going to simplify
-1/9x=3.6
Then multiply both sides by -9
(-1/9x) (-9) =3.6 (-9)
Then you just Gotta simplify
U get
X=-32.4

It makes it easier by converting the expression on the left of the equal sign to fractions( 2.4 to 12/5) Answer: X=-32.4

What is the name of the tide when the sun, moon, and earth are all aligned, causing the greatest pull for highest and lowest tides?

Question 10 options:

Low tide

Spring tide

High tide

Neap tide

Answers

Answer:

Whenever the earth, moon and sun are aligned, the gravitational pull of the moon is augmented by the gravitational pull of the sun, causing larger than average tidal ranges — meaning especially high high tides and very low low tides. These extreme tides are called “spring tides.”

Step-by-step explanation:

The answer to your question is Spring tides

Little league baseball bats have barrels that measure 2.625 inches in diameter. What is the diameter of a bat in millimeters (mm), to the nearest millimeter?

2.54 cm = 1 inch
10 mm = 1 cm

Answers

I don’t know the answer but you would have to first convert the 2.625 inches into cm and then convert the cm to mm to get your answer

Convert 2.625 inches into centimeters and then convert it again but in millimeters you will get 66.7mm
No need to find diameter because it was given there in inches just convert

2.625 inches = 6.67 centimeters
6.67cm = 66.7mm

Find the total cost with tip.
Mr .Smith goes to eat for his son's birthday. The total bill is $56.50. If Mr. Smith leaves a 22% tip. What is the tip amount? What is the total cost of the meal with tip included?

Answers

Finding the tip amount:
(56.5)(22)=1,243
1,243/100=12.43
The tip amount is $12.43.
Finding the total cost:
56.50+12.43=68.93
The total cost of the meal with tip included is $68.93.

56.50 * .22 = 12.43
56.50 + 12.43 = $68.93

3/4c-7/12+7/24c+2/3-1/6c
simplify the expression

Answers

Answer: 7/8c + 1/12

Explanation: separate the c terms and the non-c terms. 3/4c + 7/24c - 1/6c = 7/8c

-7/12 + 2/3= 1/12

therefore, it’s 7/8c + 1/12

The simplification of the given expression (3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c is (21/12)c + 1/12.

What is an expression?

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

As per the given expression,

(3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c

Combined likely terms,

⇒ (3/4)c + (7/24)c - (1/6)c - 7/12 + 2/3

⇒ (3/4 + 7/24 - 1/6)c + 2/3 - 7/12

⇒ [(18 + 28 - 4)/24]c+ (8 - 7)/12

⇒ (42/24)c + 1/12

⇒ (21/12)c + 1/12

Hence "The simplification of the given is (21/12)c + 1/12".

Answers

Answer:

(22,0)

Step-by-step explanation:

1. Select any two points given and find their slope (rise/run)

(-38, 40) and (-23, 30)

slope = [tex]\frac{40-30}{-38-(-23)}[/tex] = - 2/3

2. Use the slope and one of the points to create an equation of the line in the format y = mx + b, where m = slope and b = y-intercept.

y = mx + b ⇒ 40 = -2/3 (-38) + b

3. Solve for b

40 = -2/3 (-38) + b

40 = 76/3 + b

40 - 76/3 = b

b = 44/3

4. To find the x-intercept, set y = 0, and solve.

y = -2/3 x + 44/3

0 = -2/3 x + 44/3

2/3 x = 44/3

x = 22

Find the percent markup

A store advertises a 35% markdown on the PlayStation 5 gaming console. It normally sells for $1,019. what is the final sale price?

Answers

the final sale price would be $662.35

ANSWER: $662.35

EXPLANATION:

We know the how much the PS5 cost and we know the markdown percentage. So we need to find 35% of 1,019 because we need to know how much to take away.

35% of 1,019 = 356.65

So now we take the original price and subtract 356.65 from 1.019.

When we do this we get $662.35

2(3y + 7 + 5) = 196 - 16
what’s the value of y?
And tell me how you know this and why or Y ahahahahahaha

Answers

Answer:

y=60

Step-by-step explanation:

196 - 16 = 180

7 + 5 = 12

12 + 3y = 15y

2 * 15y = 30y

180 ÷ 30 = 60

y = 60

Answer:

y=26

Step-by-step explanation:

Let's solve your equation step-by-step.

2(3y+7+5)=196-16

Step 1: Simplify both sides of the equation.

2(3y+7+5)=196-16

(2)(3y)+(2)(7)+(2)(5)=196+-16 (Distribute)

6y+14+10=196+-16

(6y)+(14+10)=(196=-16) (Combine Like Terms)

6y+24=180

Step 2: Subtract 24 from both sides.

6y+24-24=180-24

6y=156

Step 3: Divide both sides by 6.

6y/6 = 156/6

y=26
