Let m and s be the number of math and sociology books sold respectively.
m=s+88 we are also told that:
m+s=426, using m found above in this equation gives you:
s+88+s=426 combine like terms on left side
2s+88=426 subtract 88 from both sides
2s=338 divide both sides by 2
s=169, since m=s+88
m=169+88=257
So 257 math and 169 sociology textbooks were sold.
X=1 & Y=12
X=2 & Y=20
X=3 & Y=30
Answer:
the answer of your question is B
Answer:
The first option and the third option
Step-by-step explanation:
Since the figure moved 4 places down and 4 places to the right.
The question says that the end of the cave is 380 meters below.
Lets say the sea level or the surface is at 0 meters or we can say that it is the reference level for us.
Now if we go up the height will be measured with positive integer but if we go down the depth will be represented by a negative integer.
Negative integer also represents the depth or the distance below the surface level.
Here we need to generate an integer that can represent the depth of 380 meters.
So if we are going down we will use negative integer to represent.
Therefore, the integer to represent the depth is
meters.
