Answer:
8x +5
Step-by-step explanation:
The sum is found by combining "like" terms—those that have the same arrangement of variables.
The first expression, 2x +6, has terms 2x and 6.
The second expression, 6x -1, has terms 6x and -1.
In each case, the first term listed is first-degree in the variable x. These are "like" terms, so can be added:
... 2x +6x = (2+6)x = 8x
The second term listed in each case is a constant. These are "like" terms, so can be added:
... 6 + (-1) = 5
Then the sum of the given expressions is the sum of the results from adding like terms:
... 8x + 5
X/200=65/100
200*65=100x
13,000=100x
x=130
Answer:
80.25
Step-by-step explanation:
B=3R
G=5B=15R
R+3R+15R=508.25
19R=508.25
R=26.75
3(26.75)=80.25
