Step-by-step explanation:
$1.80 per pound
The amount she's supposed to buy it is
1.80 × 12.5 = $22.5
She paid $21.25 for the 12.5 pounds, that means she saved
$22.5 - $21.25 = $1.25
the amount she saved per pound is
1.25/12.5 = $0.1 per pound
So he started with 3/4 lb and ended up with 2/3 of that so 2/3 of 3/4
'of' can be roughly translated as multiply
so 2/3 times 3/4 =6/12=1/2 lb left
or you know that there are 3 out of 4 parts pound left so 2 out of 3 parts of nuts is = 2/4 or 1/2 lb
In the rhombus, the diagonals are perpendicular.
We know, the sum of the measures of the triangle is equal 180°.
Therefore we have the equation:

<em>combine like terms</em>

<em>subtract 75 from both sides</em>
<em>divide both sides by 5</em>

<h3>Answer: x = 21°</h3>
For this case we have the following function:
F (x) = 3x ^ 2 + 6x-24
We observe that it is a quadratic equation.
The graph is therefore a parabola.
Its cut points are:
(-4, 0)
(2, 0)

Answer:
If the sum of first 6 terms is 9 times to the sum of first 3 terms of the same G.P., then common ratio of the series will be. Solution: Let a be the first term and r be the common ratio of the GP. Hence option (2) is the answer.
