The sum of 14 and a number is equal to 17
Andrews [41]

Answer:

<h2>n + 14 = 17</h2><h2>n = 3</h2>

Step-by-step explanation:

Sum of 14 and number means "n + 14" and equals 17 means "= 17."

Now that we have an equation, we can solve.

<h3>Step 1: Subtract 14</h3>

n = 3

<h3>Step 2: Check</h3>

3 + 14 = 17

17 = 17 ✔

I'm always happy to help :)

The senior classes at Snellville High and General High planned separate trips to the water park. The senior class at Snellville
Aleonysh [2.5K]

Answer:

133

Step-by-step explanation:

Snellville

12v+14b = 796

General

14v+12b =738

We need to solve for v and b where v is how many on a van and b is how many on a bus

12v+14b = 796

14v+12b =738

Divide each equation by 2

6v+7b =398

7v+6b =369

Multiply the first equation by 7 and the second equation by -6

7(6v+7b) =7(398)  

42v +49b =2786

-6(7v+6b) =369*-6

-42v -36b = -2214

Add these equations together

42v +49b =2786

-42v -36b = -2214

-------------------------------

     13b = 572

Divide each side by 13

13b/13 = 572/13

b= 44

Now find v

6v+7b =398

6v +7(44)=398

6v +308 = 398

Subtract 308 from each side

6v = 90

Divide by 6

6v/6 = 90/6

v = 15

We want 2 b and 3 v

2b+3v = 2(44)+3(15) = 88+45=133

Simplify the following expression using imaginary numbers. Express your answer in a + bi form
mamaluj [8]
<h2>Answer:</h2>

0 - 17i

<h2>Step-by-step explanation:</h2>

Given expression;

i⁸⁰ + i³⁸ - i17

To express the expression in the form a+bi;

<em>i. Rewrite the expression such that it contains terms in i²</em>

(i²)⁴⁰ + (i²)¹⁹ - i17

<em>ii. Solve the result from (i) above using the identity i² = -1</em>

We know that the square root of -1 is i. i.e

\sqrt{-1} = i

<em>Squaring both sides gives</em>

<em>=> </em>(\sqrt{-1} )^{2} = i^{2}<em />

=> -1 = i²

Therefore,

i² = -1

<em>Substitute i² = -1 in step (i) above</em>

(-1)⁴⁰ + (-1)¹⁹ - i17

<em>(iii) Solve the result in (ii)</em>

We know that the when a negative number is raised to the power of an even number, the result is a positive number. If it is raised to the power of an odd number, the result is a negative number. Therefore,

(-1)⁴⁰ + (-1)¹⁹ - i17 becomes

1 + (-1) - i17

0 - i17

<em>(iv) Write the result from (iii) in the form a+bi</em>

0 - 17i
