Answer:
- 25 pounds cashews
- 15 pounds peanuts
Step-by-step explanation:
Let c represent the number of pounds of cashews in the mix. Then 40-c is the number of pounds of peanuts. The total cost of the mix is ...
10c +2(40 -c) = 7(40)
8c +80 = 280 . . . . simplify
c +10 = 35 . . . . . . . divide by 8
c = 25 . . . . . . . . . . subtract 10
40-c = 40-25 = 15 . . . . pounds of peanuts
25 pounds of cashews and 15 pounds of peanuts should be used in the mix.
Answer:5
Step-by-step explanation:
<h3><u>(8 + 2)</u> <u>sum of values </u> = <u>10</u> = 5</h3><h3> 2 number of values 2</h3><h3 />
There is equal spacing between the mean and the extremes
8 - 5 = 3
5 - 2 = 3
Answer:
∠N = 31
Step-by-step explanation:
MN = MP
∠N = ∠P = x+3
∠M + ∠N + ∠P = 180
4x+6 + x+3 + x+3 = 6x + 12 = 180
x = 28
∠N = 28 + 3 = 31
Answer:
(b) (x -10)(x +10)
Step-by-step explanation:
The factorization of the difference of squares is a special form:
a² -b² = (a -b)(a +b)
<h3>Application</h3>
Your expression is recognizable as the difference of squares:
x² -100 = x -10²
Using the above form, the factorization is ...
= (x -10)(x +10) . . . . . . . . matches the second choice
