Answer:
(q + 4) + (d - 3) + n
Step-by-step explanation:
You have to add all of them.
You have to add q, d, and n.
so q + d + n
and then you add four more q's so
(q + 4) + d + n
and then you lost 3 dimes so
(q + 4) + (d - 3) + n
and nothing happened to n so that is the answer.

<em>commutative property</em> a + b = b + a
... (-5 + 1/2 + 5) = ... (-5 + 5 + 1/2)
<em>inverse property of addition</em> a + (-a) = a - a = 0
... (-5 + 5 + 1/2) = ... (0 + 1/2)
<em>identity property of addition</em> a + 0 = 0 + a = a
... (0 + 1/2) = ... 1/2
<em>inverse property of multiplication</em> a/b · b/a = 1
37 · 2 · 1/2 = 37 · 2/1 · 1/2 = 37 · 1
<em>identity property of multiplication</em> a · 1 = 1 · a = a
37 · 1 = 37
Answer:
3 1/5 (or 3.5)
Step-by-step explanation:
2(7) - 7(-1)
_______
7 + -1
Next:
14 + 7 (two negatives make a positive)
_____
6
Next:
21/6 which equals 3 1/2 (3.5)
Answer:
39.9
Step-by-step explanation:
A good trick to remember is SOH CAH TOA.
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
Here, we're given an angle and the opposite side, and we want to find the adjacent side. So we need to use tangent.
tan 31° = 24 / x
x = 24 / tan 31°
x ≈ 39.9
