You buy 7 books
3b+5=26
*subtract 5 to the 26 side*
3b=21
Now divide 21 by 3
B=7
So there are 7 books bought. ^^
Length BC is opposite of angle A and AC is opposite of angle B.
<span>Since we know one set of opposite angles and lengths and looking for the length where we know the opposite angle, we can use law of sines: </span>
<span>a / sin(A) = b / sin(B) </span>
<span>8 / sin(71) = b / sin(42) </span>
<span>b sin(71) = 8 sin(42) </span>
<span>b = 8 sin(42) / sin(71) </span>
<span>b ≈ 5.66 units (rounded to 2DP)</span>
I think the answer is 12
because
y=36, x=9
y=?, x=3
so you divide 36 by 3 to get the other y
Hope this helps
Answer:
–52
Step-by-step explanation:
Clear the fractions, then add 2.

In y = 2x + 3, 3 represents the fixed cost and 2 represents the cost-per-mile.
The per mile charnge, in dollars per mile, is $2/mile (answer)
