Answer:
x = 3
Step-by-step explanation:
cuz x + 2x + 3 + 3 = 3(x+2)
replace x with 3
3 + 2(3) + 3 + 3 = 3(3+2)
3 + 2(3) = 9 + 3 = 12 + 3 = 15
3(3+2) = 15
Pls can i be brainliest...
Answer:
Step-by-step explanation:
x + 2x + 3 + 3 = 3(x + 2)
Do the distributive property
x + 2x + 3 + 3 = 3 * x + 3 * 2
x + 2x + 3 + 3 = 3x + 6
Combine like terms
3x + 6 = 3x + 6
Subtract 6 on both sides
3x + 6 - 6 = 3x + 6 - 6
3x = 3x
As you can see, they are the same...which means
Any value of x makes the equation true. All real numbers
1, 2, 3 , 4 etc
Any value u put into the equation to represent "x" will be true...
EX:
3x = 3x
( if x were 7 we substitute that)
3(7) = 3 (7)
21 = 21 CORRECT
They will be the same answer/ have the same value.
Hope this helped!

Answer:
x=12, SV=30
Step-by-step explanation:
Since <S is congruent to <T, you know that line TV is equal to line SV
2x+6=3x-6
subtract 2x on both sides
6=x-6
add 6 to both sides
12=x
x=12
To find SV you need to plug in x
2(12)+6
24+6

The average speed would be 10.1 kilometers per hour.
Step-by-step explanation:
If we convert both times into minutes, it will make solving this much easier. After finding the speed for both legs, we can find the average by adding the two values together and dividing by 2. This results in 10.11430568 or can be rounded to 10.1.

please HELP MEEEEEE .A store owner wants to make a candy that sells for $1 per pound.he has 50 lb of sugar candies that cost $1.20 per pound.how many pounds of gummy candies that cost 80 cents per pound should he add.
Answer:
50 pounds
Step-by-step explanation:
we can use the equation 60+80/100x=1(x+50)
we get 80/100 x because the gummy candies are 80 cents or 80/100x
we get 60 from multiplying 1.20$ x 50 = 60
solve:
60+80/100x = x+50
60 = x-80/100x+50
60-50 = 20/100x
10 = 20/100x
x= 10 x 100/20 = 10x5= 50 pounds
Using proportions, it is found that he should add 50 pounds of gummy candies that cost 80 cents per pound.
What is a proportion?A proportion is a fraction of a total amount.
This problem is organized as follows:
There is a total of 50 + x pounds.Of those, 50 cost $1.2 per pound.x cost $0.8 per pound.The selling price is of $1.Hence:
[tex]\frac{50}{50 + x}1.2 + \frac{x}{50+x}0.8 = 1[/tex]
[tex]\frac{60 + 0.8x}{50 + x} = 1[/tex]
[tex]50 + x = 60 + 0.8x[/tex]
[tex]0.2x = 10[/tex]
[tex]x = \frac{10}{0.2}[/tex]
[tex]x = 50[/tex]
He should add 50 pounds of gummy candies that cost 80 cents per pound.

If it snows 3 inches in 6 hours, how many inches will we have after the 36 hours of snowing from this snow storm?
Answer:
6 inches of snow
Step-by-step explanation:
6x6=36
snows 3 inches in 6 hours
i
Answer:
18
Step-by-step explanation:
3 inches for every 6 hours. There are 6 6-hour groups in 36, so to find the inches in 36 hours, we would multiply the 3 inches times the 6 groups of 6-hour increments (aka 3*6). 3*6 = 18, so after 36 hours of snowing, we'd end up with 18 inches of snow.
