2(6-x)=3 please help
Answer:
x = 4.5
Step-by-step explanation:
Let's solve this together!
First you would want to multiply 6 and x:
6×2 = 12
x×2 = 2x
Then you would want to subtract 12 from 3:
3+12 = 9
Then divide 9 by 2:
9÷2 = 4.5
x=4.5
That's it!
Hope this helped! :)

If X represents the number of pictures, write an equality to represent the situation!
Answer:
The Drama Club needs to sell more than 3 pictures to make a profit.
The inequality 10x ≥ 2.55x +25 represents the situation.
Step-by-step explanation:
Given that:
Rent for lighting equipment = $25
Price per print = $2.55
Selling price of one picture = $10
x be the number of pictures.
Selling price * No. of pictures sold ≥ Price of per print * pictures printed + rent
10x ≥ 2.55x +25
10x-2.55x≥25
7.45x≥25
Dividing both sides by 7.45
[tex]\frac{7.45x}{7.45}\geq \frac{25}{7.45}\\x\geq 3.35[/tex]
Hence,
The Drama Club needs to sell more than 3 pictures to make a profit.
The inequality 10x ≥ 2.55x +25 represents the situation.

Answer:
Train B is traveling faster.
Step-by-step explanation:
To find which train is faster, divide the distance the train traveled by the elapsed time for each train:
Train A:
Distance traveled is 12.5 meters.
Elapsed time is 1 second.
12.5 ÷ 1 = 12.5
Train A travels 12.5 meters per second.
Train B:
Distance traveled is 100 meters.
Elapsed time is 4 seconds.
100 ÷ 4 = 25
Train B travels 25 meters per second.
25 is greater than 12.5, so train B travels faster.

In a painting, The Great Pyramid of Giza is 45 centimeters tall.
If the pyramid is actually 146.5 meters tall, find the scale.
Answer:
The scale is: 1 cm = 3.26 meter
Step-by-step explanation:
Given
Height of Pyramid in Painting = [tex]H_p = 45 cm[/tex]
Actual Height of Pyramid = [tex]H_a = 146.5m[/tex]
In order to find the scale, we can find the ratio between actual height and height in painting.
The ratio can be found by dividing the actual height by height in painting
[tex]Scale = \frac{H_a}{H_p}\\= \frac{146.5}{45}\\=3.25555 m/cm[/tex]
Rounding off to nearest hundredth
= 3.26
This means that the scale is:
1 cm = 3.26 meter
