Okay so we have
$1.60 x .10 = .16
1.60 - .16 = $1.44
so
1.44 x 4 = $5.76
1.44 / 2 = .72
$5.76 + .72 = $6.48
so your answer is $6.48 [B]
Answer: x = 3
Step-by-step explanation:
2(7x - 6) = 30
14x - 12 = 30
+ 12 +12
14x = 42
/14 /14
x = 3
Answer:
12 pounds
Step-by-step explanation:
One quantity is asked for, so it is convenient to let a variable represent that. We can use x to represent pounds of chocolate. Then the total cost of the mix is ...
19.30·x + 3.50·18 = 9.82·(x +18) . . . . cost of chocolate + cost of trail mix
9.48·x = 113.76 . . . . . . simplify, subtract 63+9.82x
113.76/9.48 = x = 12 . . . . . . divide by the coefficient of x
The owner needs to mix 12 pounds of chocolate. (no rounding necessary)
X^3+3x^2+5x+8/x+1
multiply the whole equation by x
x^4+3x^3+5x^2+8+1x
x^4+3x^3+5x^2+x+8
factor out by parts
(x^2-0.641604x+1.33244)(x^2+3.6416x+6.00403)
Answer:
84 is .4 of the trip
40% times 2.5 is 100% (40+40+20)
so, multiple 84 by 2.5 and that's the answer
84 * 2.5= 210
