Answer:
$2.59 per pound of bark.
Step-by-step explanation:
Convert 3 tons to pound
1 ton = 2,000 pounds.
3 x 2,000 = 6,000
Now divide the $ and the pounds to find the $ per pound rate
6,000 ÷ 15,540 = 2.59
$2.59
X= number of nickels
3x= number of dimes
Each nickel is $0.05 and each dime is $0.10. Multiply each coins monetary value by the quantity of each. Add them equal to the total $9.10.
(0.05 * x) + (0.10 * 3x)= 9.10
multiply inside parentheses
0.05x + 0.3x= 9.10
add
0.35x= 9.10
divide both sides by 0.35x
x= 26 nickels
DIMES
3x= 3(26)= 78 dimes
CHECK:
(26 nickels * 0.05) + (78 dimes * 0.10)= 9.10
$1.30 + $7.80= $9.10
$9.10= $9.10
ANSWER: There are 26 nickels and 78 dimes.

X2+12x+35 should be written as <span>x^2+12x+35, where "^"
denotes exponentiation.
Since the coefficient of the x^2 term is 1, we can focus on 35, finding its factors. Note that 35 = 1*35, 5*7. Also note that 5+7 = 12.
Thus, </span>x^2+12x+35 can be re-written as (x+5)(x+7). As a check, multiply 5 and 7; you get 35, which matches the original <span>x^2+12x+35. Then add 5x to 7x, obtaining 12x, which also matches.</span>
If there is suppose to be a negative sign.
3x -1(2x + 4x - 6)
Distribute the -1 to all terms within the parenthesis
-1(2x + 4x - 6) = -2x - 4x + 6
3x - 2x - 4x + 6
Simplify. Combine like terms
(3x - 2x - 4x) + 6
-3x + 6
-3x + 6 is your answer
hope this helps
