Answer: The total number of colored papers is 18.
Step-by-step explanation:
Given: The ratio of coloured papers to wight papers is 3:8.
Let total number of colored papers = 3x
and total number of wight papers = 8x
Since, there are 48 wight papers , then
Now , number of colored papers = 3(6)=18
Hence, the total number of colored papers is 18.
Answer:
k = 5
Step-by-step explanation:
y = kx
15 = k(3)
k = 15/3
k = 5
Answer:
3x+0.3=3.3.
\ /
We move all terms to the left:
3x+0.3-(3.3.)=0
We add all the numbers together, and all the variables
3x+0.3-0=0
We add all the numbers together, and all the variables
3x+0.3=0
We move all terms containing x to the left, all other terms to the right
3x=-0.3
x=-0.3/3
x=-0.3/3

6x² - 5x + -21 = 0
Because this whole equation equals zero, we must simply factorize the first half of the equation, or the left side.
(3x - 7)(2x + 3) = 0
I was never really taught a specific way to factorize, so I usually just guess and check when factorizing. It usually takes a long time, it always gives you the tight answer.
Then, take each equation and make it equal zero.
3x - 7 = 0 AND 2x + 3 = 0
3x - 7 = 0
Add 7 to both sides.
3x = 7
Divide both sides by 3.
x = 7/3
Now, we do our second equation.
2x + 3 = 0
Subtract 3 from both sides.
2x = -3
Divide both sides by 2.
x = -3/2
So, x = 7/3 AND x = -3/2
So, your answer is C) x = 7/3, x = -3/2

The total worth of the 4 pounds and 8 ounces of box is $1800
<h3>Total cost</h3>
Weight of the boxes:
- 4 pounds
- 8 ounces
- Cost of each pound = $400
Convert ounces to pounds:
8 ounces to pounds = 0.5 pounds
Total cost of the boxes = 4 pounds (400) + 0.5 pounds (400)
= 1600 + 200
= $1,800
