Step-by-step explanation:
Answer:$36.40
Step-by-step explanation
16 ounces in 1 pound
0.65 x 16 = $10.40
Peanuts
0.65 x 8 = $5.2 (you do this to get the extra 8 ounces)
$10.40 + $5.2 = $15.6
Pecans
$10.40 + $10.40 = 20.8
Total
$15.6 + 20.8 = $36.40
This is the answer 3.4392.55*10^4

Step-by-step explanation:
Answer:
B, D, E
Step-by-step explanation:
-8x - 6y = 10
x + 7y = 9
You can multiply any of these equations by a constant without changing the solution.
B. 4x + 3y = -10 is equivalent to multiplying each side of the first equation by -½.
D. -16x - 12y = 20 is equivalent to multiplying each side of the first equation by 2.
E. 3x + 21y = 27 is equivalent to multiplying each side of the second equation by 3.
A. -2x + 7y = 9 is wrong. The signs don't match those of the second equation.
C. 24x + 18y = 10 is wrong. The signs don't match those of the first equation.
F. x - 14y = -18 is wrong. The coefficient of x should be -2.
