Answer:
40 pounds
Step-by-step explanation:
Given: Cost of a candy
=
per pound
Cost of candy 
Total amount of mixture of be produced = 
Selling price of mixture = 
Let´s x be the amount of
to be mixed in the mixture.
∴ Cost of
in the mixture = 12x
Next, Cost of
in the mixture = 
And we know the cost of final mixture = 
Now, putting all the value in the equation
⇒ 
⇒ 
⇒ 
∴ 
∴ 40 pounds of candy worth $12 per pound to be mixed in the mixture.
Answer: 13
Step-by-step explanation:
Area = 165
Area of square is :
Area = length × length
Let length be l
165 = l ^ 2
Square both side
l = sqrt(165)
l = 12.85
l = 13 to the nearest whole number
Answer:
5 dollars
Step-by-step explanation:
multiply 100 and 1.25 and get 125 then 130 minus 125 is 5 hope this helps god bless
Since angles EFA, AFB, and BFC lie on a straight line, then they must add up to 180° (angle sum of a straight line)
So, 7x + 4 + 8x + 6 + 6x + 2 = 180
21x + 12 = 180
21x = 168
x = 8
Answer:
Only (-2, 9) is the solution of the equation.
Hence, option 'b' is correct.
Step-by-step explanation:
Given the equation
y = -2x+ 5
<u>Checking the ordered pair (2, -9)</u>
substituting x = 2 and y = -9 in the equation
y = -2x + 5
-9 = -2(2) + 5
-9 = -4 + 5
-9 = 1
FALSE!
L.H.S ≠ R.H.S
Thus, the ordered pair (2, -9) is NOT a solution of the equation.
<u>Checking the ordered pair (-2, 9)</u>
substituting x = -2 and y = 9 in the equation
y = -2x + 5
9 = -2(-2) + 5
9 = 4 + 5
9 = 9
TRUE!
L.H.S = R.H.S
Thus, the ordered pair (-2, 9) is a solution of the equation.
Conclusion:
Only (-2, 9) is the solution of the equation.
Hence, option 'b' is correct.
