Mathematics

Basile [38]3 years ago

Answer:

40 {}^{ \frac{1}{2} }

Step-by-step explanation:

The last one is also the answer

Using the rational exponet rule,

\sqrt[n]{ {x}^{m} }  = x {}^{ \frac{m}{n} }

Using this number,

\sqrt{40}

40 is the base so it will stay same. Remember this is a square root sign so our nth root is 2 so our denominator if the rational exponet is 2.

40 {}^{1}  = 40

so our numerator is 1 so

40 {}^{ \frac{1}{2} }

Solve for x:<br><br> 17x - 12 = 114 + 3x<br><br> Thanks!
wel

Answer:

x = 9

Step-by-step explanation:

Simplifying

17x + -12 = 114 + 3x

Reorder the terms:

-12 + 17x = 114 + 3x

Solving

-12 + 17x = 114 + 3x

Solving for variable 'x'.

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

Add '-3x' to each side of the equation.

-12 + 17x + -3x = 114 + 3x + -3x

Combine like terms: 17x + -3x = 14x

-12 + 14x = 114 + 3x + -3x

Combine like terms: 3x + -3x = 0

-12 + 14x = 114 + 0

-12 + 14x = 114

Add '12' to each side of the equation.

-12 + 12 + 14x = 114 + 12

Combine like terms: -12 + 12 = 0

0 + 14x = 114 + 12

14x = 114 + 12

Combine like terms: 114 + 12 = 126

14x = 126

Divide each side by '14'.

x = 9

Simplifying

x = 9

How many miles pls help me!!!
lozanna [386]
The answer would be 7 miles. I can see that the initial charge is $35. For every mile there is a $2 fee. I found this by looking at how much the fee increases from 1 mile to 3 miles. There’s a $4 increase. So $4 divided by 2 miles is equal to 2. 1 mile is equal to $2 after the initial price. I counted by 2s from 41 to 49. Every count of 2 is a mile. When I landed on 49 I was at the 7th mile. A half of a mile is equal to $1. I know this because from 7 miles to 8.5 miles, there is a $3 increase. The 8th mile would be $51, but the half of a mile increases the cost by $1. Sorry if it’s very wordy. The answer is 7 miles though!

Find each difference and show work please !!
Ede4ka [16]

Answer:

X-19

Step-by-step explanation:

First you need to distribute the three into the numbers in the parenthesis,

(3 * x) + (3  * -5) - (2x + 4)

That then turns into,

3x - 15 - (2x + 4)

but we aren't done distributing yet, because the second set of parenthesis has a negative sign in front of it we also have to distribute that. (this is because the negative sign is really just -1)

3x - 15 + (-1 * 2x) + (-1 * 4)

that turns into,

3x - 15 - 2x -4

from here all we have to do is add like terms,

(3x - 2x) + (-15 + -4)

and that leaves us with: 1x -19 or x-19

Hope that helped :))

Bryan and Jadyn had barbeque potato chips and soda at a football party. Bryan ate 3 oz of chips and drank 2 cups of soda for a t
Diano4ka-milaya [45]

Answer:

200 mg sodium is in 1 oz of chips and 50 mg sodium is in 1 cup of soda.

Step-by-step explanation:

Let x mg sodium is in 1 oz of chips and and y mg is in 1 cup of soda.

∵ Bryan ate 3 oz of chips and drank 2 cups of soda for a total of 700 mg of sodium.

i.e. 3x + 2y = 700 --------(1),

Jadyn ate 1 oz of chips and drank 3 cups of soda for a total of 350 mg of sodium.

i.e. x + 3y = 350 ---------(2),

Equation (1) - 3 × equation (2),

We get,

2y - 9y = 700 - 1050

-7y = -350

\implies y = \frac{-350}{-7}= 50

From equation (1),

3x + 2(50) = 700

3x + 100 = 700

3x = 700 - 100

3x = 600

\implies x = \frac{600}{3}=200

Hence, 200 mg sodium is in 1 oz of chips and 50 mg sodium is in 1 cup of soda.
