Solve A+B+C=180 (solve for "B")

1 answer:

4 0

Hi the answer is b=180-a-c
We have to subtract a from both sides
a+b+c+-a=180- a
b+c= 180 - a
Now subtract c from both sides
b+c-c = 180 - a - c
b=180 - a - c

An animal shelter spends $3.50 per day to care for each bird and $6.50 per day to care for each cat. Brooklyn noticed that the s

Vikki [24]

Solution: Let $x$ be the number of birds and $y$ be the number of cats.

$x+y=29 \implies y=29-x$

$3.50 x +6.50 y= 146.50$

$3.50 x+6.50(29-x)=146.50$

$3.50x+188.5-6.5x=146.50$

$3x=188.5-146.50$

$3x=42$

$x=\frac{42}{3} =14$

Therefore, there were 14 birds at the shelter on Friday
