first combine like terms so 2n + 7n which is 9n
so 9n + 7 = 13 + 3n + 8n
then combine on other side so 9n + 7 = 13 + 11n
then subtract 7 to 13 so 6
sp 9n + 6 = 11n
then subtract 9 to the other side so 2n
6 = 2n then divide all by 2
n= 3
Answer:
X^2-x- 8/x+4
Step-by-step explanation:
X+4 becomes a negative 4
Then multiply -4 by the first number which is 1 so -4×1 is -4. Then subtract -4 by the second number 3. This gives you -1 so multiply that by 4 which is -4. Then subtract 4 from the third number -4. So that'll give you -8. Then add an x-value to every number except the very last number as that number will be you remainder.
To find the amount he spent on bags of mulch you must take the cost of the shovel away from the total, giving the equation:
46.16-14.75=3.49x
To covert this to whole numbers, multiply by 100
4616-1475=349x
3141=349x
x=9
The correct answer is B. y=-3x+4
