We should first simplify the right side, and doing so will get x/3+6=x/3+10. WE then subtract x/3 on both sides to get 6=10. Since this cannot be true, there are no solutions.
Answer:
no solution
Step-by-step explanation:
[tex]\frac{x}{3}[/tex] + 6 = 2([tex]\frac{x}{6}[/tex] + 5) ← distribute parenthesis by 2
[tex]\frac{x}{3}[/tex] + 6 = [tex]\frac{x}{3}[/tex] + 10 ( subtract 6 from both sides )
[tex]\frac{x}{3}[/tex] = [tex]\frac{x}{3}[/tex] + 4 ( subtract [tex]\frac{x}{3}[/tex] from both sides )
0 = 4 ← False statement
This indicates the equation has no solution

Solve the formula c = 5p + 215 for p
Answers
Answer:
1/5c -43 =p
Step-by-step explanation:
c = 5p + 215
Subtract 215 from each side
c-215 = 5p +215-215
c-215 = 5p
Divide each side by 5
c/5 -215/5 = 5p/5
1/5c -43 =p

when 7 is added to 3 times a number, the sum is multiplied by 2 and 15 is subtracted what is the final answer
Answers
Answer:
2(3x+7) -15
Step-by-step explanation:
Let x = unknown number
7 is added to 3 times a number
3x+7
Multiply the sum by 2
2(3x+7)
Subtract 15
2(3x+7) -15
Answer:
Let the required number be " x "
Now, 7 is added to 3 times a number : (3x + 7)
Next, the sum is multiplied by 2 : 2(3x + 7)
And then, 15 is substracted from it : 2(3x + 7) - 15
2(3x + 7) - 15 is the final answer.Point V is on the line segment UW. Given VW=5x-4, UV=2x, and UW=5x, determine the numerical length of VW

The following represents slopes of two lines. Which answer choice describes the two lines? m = 7 and m = -7
Answers
Answer:
m = 7 can also be y=7x+1 is positive and shows acceleration or ascending lines steep y axis 1 and x axis 0 ascending to 1 or above and when y = 7 x =1 see attached.
m = -7 is negative and shows deceleration of 1 as we add 1 here too. Or can be any number for y intercept see attached.
Step-by-step explanation:
The slopes of two lines are given as:
m = 7
m = -7
A line with a positive slope of 7 rises as it moves to the right, and a line with a negative slope of -7 falls as it moves to the right.
Therefore, the two lines have slopes that are opposite in sign and have the same magnitude. This means they are two straight lines that are mirror images of each other, reflected across the x-axis.
Graphically, they would look like this:
