Answer:

use of  Wires , Clamps , and measuring tools

Step-by-step explanation:

To ensure parallel rails we can use : Wires , Clamps , and measuring tools as well

The use of wires are very effective and most stressful and they are used mostly when working with wooden rails  , while you can use Clamps and other measuring tools for every kind of rails to ensure they are parallel.

Answer is 7

step-by-step explanation:

you would do 2/9 times 18 which is 4 you would subtract 18 - 4 which is 14 then you would do 14 / 2 and your answer will be seven

Answer:

x = 14

m<D = 57

Step-by-step explanation:

All triangle interior angles add up to 180.

<D and <E are congruent because of the congruent legs which makes them congruent angles:

4x + 1 + 4x + 1 + 5x - 4 = 180

13x - 2 = 180

13x = 180 + 2

13x = 182

x = 14

m<D:

4x + 1

4(14) + 1

56 + 1

57

hiiii i would love to answer yoyr question all you have to do is the bottom line which is x from the 1 count all the way until 5 and that is your answer for the first one and then for the y from the 4 count all the way until the 13 and that will give you your answer so ( , )

Answer:

9.144meters

Step-by-step explanation:

Given data

We are expected to perform unit conversion in this problem

2.54cm is equivalent to 1 inch

100cm equal to 1 meters

360 inches to cm  will be

=360*2.54

= 914.4cm

914.4cm to meters will be

=914.4/100

=9.144meters

Answer:

Sometimes

Only when x=2 then the output would be 0 for both

Answer:

a) - 10

Step-by-step explanation:

The two angles are vertical angles:

Angles that have a common vertex and whose sides are formed by the same lines.

Therefore, set your formula up as following

x+5=2x-5

x + 5 - 2x = -5

-x + 5 = -5

-x = -10

Answer: [tex]103,108[/tex]

Step-by-step explanation:

Given

There are total of 211 coins

The worth of the coins is [tex]\$37.30[/tex]

Suppose there are x dimes and y quarters

A dime is equivalent to 10 cents and quarter is equivalent to 25 cents

[tex]\therefore x+y=211\quad \ldots(i)\\\Rightarrow 0.1x+0.25y=37.30\\\Rightarrow x+2.5y=373\quad \ldots(ii)[/tex]

Solving (i) and (ii) we get

[tex]x=103,y=108[/tex]

Therefore, student collects 103 dimes and 108 quarters.

a. s = n/8

b. the independent variable is s

the dependent variable is n

Answer: 8

Step-by-step explanation:

Given

Lian has [tex]\$1.00[/tex] and she has twice as many dimes as nickels

Suppose she has [tex]x[/tex] nickels

So, the number of dimes is [tex]2x[/tex]

Nickel is equivalent to 5 cents and dime is equivalent to 10 cent

[tex]\therefore \ x(0.05)+2x(0.1)=1\\\Rightarrow 0.05x+0.2x=1\\\Rightarrow 0.25x=1\\\Rightarrow x=4[/tex]

Therefore she has 8 dimes with her.

Answer:

24

Step-by-step explanation:

let 'x' = number

x/2 - 2 = 10

add 2 to each side to get:

x/2 = 12

cross-multiply to get:

x = 24

Answer:

============================================================

Explanation:

x = the number you think of

x/2 = the result after taking half of that number

(x/2) - 2 = subtract 2 from the previous result

(x/2) - 2 = 10 is the equation to solve

Solving said equation gets us...

(x/2) - 2 = 10

x/2 = 10+2 ... adding 2 to both sides

x/2 = 12

x = 12*2 ..... multiplying both sides by 2

x = 24

Notice how we basically undo everything applied to x. First we divided by 2, then we subtracted 2. So we follow that order in reverse to undo the "minus 2" (ie add 2 to both sides). Then we undo the division to multiply both sides by 2 to end up with the answer x = 24

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

Let's check that answer:

x = 24

x/2 = 24/2 = 12 ... result after taking half of x

(x/2) - 2 = (12)-2 = 10 ... result after subtracting two

We end up with 10 as your teacher mentioned, so it confirms that x = 24 is the answer.

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

Here's another way to check:

(x/2) - 2 = 10

(24/2) - 2 = 10

(12) - 2 = 10

10 = 10

We end up with the same thing on both sides, so x = 24 is confirmed.

Answer:

For question 2 :

1 <

2>

3=

Step-by-step explanation:

Basically those triangle arrow things are called 'greater than signs'

So , you need to say which number is bigger than the other or if they are equal. For example :

3>1

1<7

1=1

Answer:

2. 786.20 is greater than 476.2 593.99 is greater than 59.399 and the last one are equal to each other 3. 12 quarts of flour 4. Go up three and to the right three

Answer:

w=18

Step-by-step explanation:

So, lets go over what we know:

A line is 180 degrees.

5w+36 is the first part of the line.

3w is the other part of the line.

So 5w+36 and 3w is 180 degrees.

We can write this as:

5w+36+3w=180

Combine the 5w and 3w:

8w+36=180

Subtract 36 from both sides:

8w=144

Divide 8 from both sides to get w alone:

w=144/8

=

w=18

Hope this helps!

Answer:

180

Step-by-step explanation:

It is one. A strait line so it is 180

Answer:

.8

Step-by-step explanation:

To write the equation of a line in slope-intercept form, there are two things we need: the y-intercept and the slope.

To find the y-intercept using a graph is relatively easy. We are looking to see where the line crosses the y-axis. In this case, that is at the point (0,4).

To find the slope, we need to first find two points that are on the line. I will be using the points (0,4) and (2,5), though you can use any two that you would like. Then, we'll need to use the slope formula (y2 - y1 / x2 - x1).

(5 - 4) / (2 - 0)

1 / 2 = slope

Now that we have the slope and y-intercept, we can simply plug those values into slope intercept form, y = mx + b, where m is the slope and b is the y-intercept.

Therefore, our equation of the line in fully simplified slope-intercept form is y = 1/2 x + 4.

Hope this helps!! :)

Answer:

y = 1/2x + 4

Step-by-step explanation:

Slope-intercept form is: y = mx + b

The slope is 1/2 (mx)

Up 1, Over 2, which is the space between each dot.

The y-intercept is 4 (b)

The point where the line crosses the y-axis.

y = 1/2x + 4

Hope this is correct for you!

Answer:

3/10

Step-by-step explanation:

From the question, we have the total number of sampled students as 30

9 students said 7 was their favorite

So the experimental probability that we have 7 picked as the favorite number will be the number of respondents who chose 7 as their favorite divided by the total number of respondents

We have this as;

9/30 = 3/10

Answer:

x = 94

Step-by-step explanation:

[tex]x + (\frac{1}{2}x + 39) = 180[/tex]

1.5x + 39 = 180

Subtract 39 from each side.

1.5x + 39 - 39 = 180 - 39

Simplify.

1.5x = 141

Divide each side by 1.5.

1.5x ÷ 1.5 = 141 ÷ 1.5

x = 94

Answer:

20% coupon

Step-by-step explanation:

20% of 32.50 = 6.5

32.50 - 6.50 = 26

32.50 - 5 = 27.50

26 is less than 27.50, therefore, the 20% off coupon should be used to save him $1.50.
