Eg. d stands for the number of dimes, n stands for the number of nickels
a dime worth 10 cents, 1 nickel worth 5 cents
The equation for "There are 10 coins in a jar" is
d + n = 10
The equation for "The coins are worth a total of 70 cents" is
10d + 5n = 70
You said that A = (s-2) 180
Divide each side by 180 : A/180 = s-2
Add 2 to each side: A/180 + 2 = s
The total number of snakes in the zoo is 10.
<h3>How to use ratio to find the number of snake?</h3>
The number of snake can be found using ratio as follows:
The animals in the zoo are lions, tigers and snakes and he has them in the ratio of 5 : 3 : 2. The total animal is 50 animals.
Therefore,
total snakes = 2 / 10 × 50
total snakes = 100 / 10
total snakes = 10
Therefore, the total number of snakes in the zoo is 10.

Answer:
about 27.6
Step-by-step explanation:
The sum of interior angles for this rectangle is 1080
119+140+124+6x+132+132+102 = 1080 add like terms
749 + 12x = 1080 subtract 749 from both sides
12x = 331 divide both sides by 12
x = 27.6 approximately
