This essentially means 12-8
|| means absolute value which is the distance from 0 the number is
Basically it’s the number but positive
So the answer is 4
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.
Answer:
about 6.6 years
Step-by-step explanation:
41,500=14,000*.45*x
41,500=6,300*x
41,000/6,300=x
6.5873=x
6.6=x
Step-by-step explanation:
4+7=11
11+(7+4)=22
22+(7+8)=37
Every step 7+4n you must add
