Leslie tunes musical instruments. Leslie tuned a guitar with 6 strings today. Then she tuned a piano with 37 times as many strin

e-lub [12.9K]

Answer: The piano has 222 strings, because 37×6=222.

Step-by-step explanation:

Since we are informed that Leslie tuned a guitar with 6 strings today and that she then tuned a piano with 37 times as many strings.

This simply means that we have to multiply 37 by 6 strings to get the value of the strings of the piano that she tuned. This will be:

= 6 × 37

= 222 strings.

Leslie tuned 222 strings.

Therefore, the piano has 222 strings, because 37×6=222.

Does anyone know how to do these? I don’t want the answers I need someone to explain how to do them so I can solve it. Thanks

Hi! This type of equation is actully really simple to solve once you learn how so I'll only do a few and let you solve the rest.

To solve 3x + 6 = 18 you just need to remember that whatever action you do on one side of the equal sign you have to do on the other as well, and you just need to get the variable isolated on one side and the constant on the other.

So subtract 6 from both of the constants (6 and 18) to get to 3x = 12.

Then divide both sides by 3 to isolate x and you get x = 4.

To solve x/7 -9 = -7 you have to add 9 to both sides to get x/7 = 2. Then because it's a fraction with a denominator of 7 you multiply both sides by 7 to get x = 14.

To solve 8x - 2x = -36 you combine like terms to get 6x = -36 then divide both sides by 6 to get x = -6.

Hope this is what you were looking for and explained in an understandable way, if not I apologize. :)

Help on question 7. It is similar figures

Temka [501]

The answer is nine, because the ratios need to stay equal. 9+3=12, 6+3=9

Find an equation of the line that goes through the points (10,34) and (-1,10)

kotykmax [81]

Answer:

Given points are ( 10 ,34 ) and ( -1 , 10)

Step-by-step explanation:

<em>The </em><em>equation</em><em> </em><em>of </em><em>line </em><em>is </em><em>given </em><em>by </em>

<em>first </em><em>we </em><em>can </em><em>find </em><em>slope </em><em>(</em><em>m</em><em>) </em>

<em>=</em><em> </em><em>(</em><em>y2 </em><em>-</em><em> </em><em>y</em><em>1</em><em>)</em><em> </em><em>/</em><em> </em><em>(</em><em> </em><em>x2</em><em> </em><em>-</em><em> </em><em>x1</em><em>)</em>

<em>=</em><em> </em><em>3</em><em>4</em><em>-</em><em>1</em><em>0</em><em>/</em><em>1</em><em>0</em><em>+</em><em>1</em>

<em> </em><em>=</em><em>2</em><em>4</em><em>/</em><em>1</em><em>1</em>

<em>Now </em><em>the </em><em>equation </em><em>is</em>

<em>y </em><em>-</em><em> </em><em>y1 </em><em>=</em><em> </em><em>m </em><em>(</em><em> </em><em>x </em><em>-</em><em> </em><em>x1) </em>

<em>y </em><em>-</em><em> </em><em>1</em><em>0</em><em> </em><em>=</em><em> </em><em>2</em><em>4</em><em>/</em><em>1</em><em>1</em><em> </em><em>(</em><em> </em><em>x </em><em>+</em><em>1</em><em>1</em><em>)</em>

<em>11 </em><em>(</em><em> </em><em>y </em><em>-</em><em> </em><em>1</em><em>0</em><em> </em><em>)</em><em> </em><em>=</em><em> </em><em>2</em><em>4</em><em> </em><em>(</em><em>x </em><em>+</em><em> </em><em>1</em><em>1</em><em>)</em>

<em>11y </em><em>-</em><em> </em><em>1</em><em>1</em><em>0</em><em> </em><em>=</em><em> </em><em>24x </em><em>+</em><em> </em><em>2</em><em>6</em><em>4</em>

<em>24x </em><em>+</em><em> </em><em>2</em><em>6</em><em>4</em><em> </em><em>+</em><em>110-11y </em><em>=</em><em>0</em>

<em>24x </em><em>-</em><em> </em><em>11y </em><em>+</em><em> </em><em>3</em><em>7</em><em>4</em><em> </em><em>=</em><em> </em><em>0</em>

<em>which </em><em>is </em><em>the </em><em>required </em><em>equation </em>

Find the equation of the line that passes through the points (–2, 4) and (1, 2).

Stolb23 [73]

Answer:

The answer to your question is c) y = (-2/3)x + 8/3

Step-by-step explanation:

Data

A (-2, 4)

B (1, 2)

Process

1.- Calculate the slope of the line

-Formula

m = (y2 - y1)/(x2 - x1)

x1 = -2 y1 = 4 x2 = 1 y2 = 2

-Substitution

m = (2 - 4) / (1 + 2)

-Simplification

m = -2/3

2.- Find the equation of the line

Formula

y - y1 = m(x - x1)

-Substitution

y - 4 = -2/3 (x + 2)

-Simplify

y - 4 = (-2/3)x - 4/3

y = (-2/3)x - 4/3 + 4

y = (-2/3)x - 4/3 + 12/3

-Result

y = (-2/3)x + 8/3
