There are 8 problems in the picture.  What you need is for someone to give you
some tips and solve one or two of them. 
Giving you a bunch of answers and nothing else does NOT help you.

Here are my tips to you:

A).  You're always trying to find the number that the unknown letter must be equal to,
in order to make the equation a true statement.  That's the solution to the equation,
and the 'answer' to the problem.  

B).  Always do what you have to do in order to get the letter all by itself on one side.

C).  Whatever you do to one side of the equation, you must do to the other side.

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

Examples, from the picture:

<u>#3:</u>  <u>8x - 2 = -9 + 7x</u>    What can you do to get the 'x' all alone on one side?

Subtract 7x from each side:    x - 2 = -9

Add 2 to each side:            <u>x = -7</u>
===========================================
<u>#2:</u>  <u>6 = 1 - 2n + 5</u>  

Combine the 1 and the +5 on the right side:      6 = 6 - 2n

What can you do to get the 'n' all alone on one side?

Subtract 6 from each side:      0  =  - 2n

Divide each side by -2 :      <u> 0 = n</u>
===========================================
<u>#5:</u>  <u>4m - 4 = 4m</u>

Subtract 4m from each side:    - 4 = 0

There is no number for 'm' that can make -4 equal to zero.
So this equation has <u>no solution</u>.
(That's OK.  Not every equation must have a solution.)

GAMING In a video game, the user navigates a character across an unknown land using a map. On the map, the distance between the
soldi70 [24.7K]

The question is an illustration of scale drawing

The character have to travel 8.5 km in the game to visit all three destinations and return to their starting point

<h3>How to calculate the actual distance</h3>

The distance on the map are given as:

A =2 cm

B = 8 cm

C = 7 cm

The total distance on the map would be:

Total =2cm + 8cm + 7cm

Total =17cm

The actual distance between the store and the dungeon is 4 kilometers.

This means that:

B' =4km

So, we have:

Scale = B : B'

Scale = 8cm : 4km'

Represent the required actual distance with x.

So, we have:

17cm : x = 8cm : 4km

Express as fraction

\frac{x}{17} = \frac 48

Multiply both sides by 17

x = \frac 48 * 17

x = 8.5

Hence, the actual distance travelled is 8.5 km

There are 1,295 students attending a small university.There are 714 women enrolled. What percent of the students are women. Equa
Semenov [28]
If 1295 × p = 714, then you can rearrange the equation to find the percentage.

You have to get p on its own, so you divide 1295 on both sides of the '='.

1295 × p = 714

p = 714 ÷ 1295

p = <span>0.55135135135...

p </span>× 100 = actual percentage

actual percentage = 55.14%

The longest human power sporting event is the tour de France cycling race in a particular year the average speed for the winner
sergey [27]

Answer:

The winner completed the race in 96 hours and 52 minutes.

Step-by-step explanation:

Given:

Distance of the cycling race = 2292 miles

Average speed of the winner = 23.66\  mph

We need to find time required by winner to complete the race.

Solution:

Now we know that;

Time required can be calculated by dividing Total Distance from the Average speed.

framing in equation form we get;

time required by winner to complete the race = \frac{2292}{23.66} = 96.87\ hrs

Now converting 0.87\ hrs into minutes we get;

0.87\times 60= 52.2\approx 52\ mins

Hence the winner completed the race in 96 hours and 52 minutes.

The ratio of games won at to the games lost for a basketball team is 3:2. The team won 18 games. How many games did the team los
schepotkina [342]

A ratio of 3:2.

The easiest way to go about this is to divide the actual number of wins (18) by its corresponding element in the ratio.

So:

\frac{18}{3}= 6

This means every element on the ratio has a value of 6.

The amount of element in the ratio that correspond to losses is 2.

Multiply the actual amount of matches per element in the ratio by the number of elements that represents the losses in the ratio.

6*2=12

Your answer:

<em>"The team lost 12 games."</em>

Write an equation in slope intercept form for a line that passes through the origin with a slope of 3/2
mrs_skeptik [129]

Answer: y = (3/2)x

m = 3/2 is the slope

(x1,y1) = (0,0) is the point we want the line to go through, aka the origin

Use point slope form, plug in the given values, and convert to slope intercept form

y - y1 = m(x - x1) .... point slope form

y - 0 = (3/2)*(x - 0) .... substitution

y = (3/2)x .... final answer in slope intercept form
