Answer:
D) 4
Step-by-step explanation:
−9 + 12 + (unknown) + −8 = −1
<em>Start by going through and testing each option</em>
−9 + 12 + 2 + −8 =
3 + 2 + −8 =
5 + −8 =
−3
−3 ≠ −1
<em>A) 2 is not possible.</em>
−9 + 12 + −2 + −8 =
3 + −2 + −8 =
1 + −8 =
−7
−7 ≠ −1
<em>B) </em>−<em>2 is not possible.</em>
−9 + 12 + −4 + −8 =
3 + −4 + −8 =
−1 + −8 =
−9
−9 ≠ −1
<em>C) </em>−4<em> is not possible.</em>
<em>From this, D is looking like the answer. But to be sure, test it.</em>
−9 + 12 + 4 + −8 =
3 + 4 + −8 =
7 + −8 =
−1
−1 = −1
<em>D) 4 is the answer.</em>
Answer:
3
⋅
x
x
+
y
Explanation:
The product of 3 and x divided by the sum of x and y is
P
r
o
d
u
c
t
o
f
3
and
x
S
u
m
o
f
x
and
y
.
Okay break it into smaller parts. The product of
3
and
x
is
3
⋅
x
um of
x
and
y
is
x
+
y
Now, we get
3
⋅
x
x
+
y
and that's it
