Answer:
$7.14
Step-by-step explanation:
Let p, d, q represent the numbers of pennies, dimes, and quarters in the collection, respectively.
p + d + q = 45 . . . . . . . . there are 45 coins in the collection
2p +5 = q . . . . . . . . . . . . 5 more than twice the number of pennies
p + 4 = d . . . . . . . . . . . . . 4 more than the number of pennies
Substituting the last two equations into the first gives ...
p +(p +4) +(2p +5) = 45
4p = 36 . . . . . . . . . . . . . subtract 9
p = 9 . . . . . . . . . . . divide by 4
d = 9 +4 = 13
q = 2(9) +5 = 23
The value of the collection is ...
23(0.25) +13(0.10) +9(0.01) = 5.75 +1.30 +0.09 = 7.14
The coin collection is worth $7.14.
Reflecting the triangle ABC implies that the new position would be a mirror of the previous position
The statement that logically comes next is (c) Translate triangle ABC, so that point A maps to point W
<h3>How to determine the next step</h3>
After reflecting the triangle ABC, the next step is to map point A to point W on the coordinate plane.
This is done by translating the triangle ABC i.e. by shifting or moving the triangle ABC so that points A and W would be on the same point
Hence, the statement that logically comes next is (c)

hope it helps.
x= 1/6
Answer:
x = -1,-5
Step-by-step explanation:
X^2 + 3x + 5 = -3x
x^2 + 6x + 5 = 0
(x + 5)(x + 1) = 0
x = -1,-5
