Number of tiguers: x + 2
Number of Lions: x
Number of bears:(x+2)+1=(x+3)
We can suggest this equation:
(x+2) + (x)+(x+3)=20
3x+5=20
3x=20-5
3x=15
x=15/3
x=5.
Therefore:
Number of tiguers: x + 2=5+2=7
Number of Lions: x=5
Number of bears:(x+2)+1=(x+3)=5+3=8.
Answer: there are 7 tiguers, 5 lions and 8 bears.
Answer:
x = (2600/4000) × 100%
x = 0.65 × 100%
x = 65%
Step-by-step explanation:
The percentage equation that can be used to find the percent of books that are fiction can only be found where the number of fiction books is known and the total number of books available is known as well.
Given;
Number of fiction books = 2,600
Number of books = 4,000
let the percent of books that are fiction be x
x = (2600/4000) × 100%
x = 0.65 × 100%
x = 65%
Answer:
d = 5t + 20
Step-by-step explanation:
d represents the distance and t represents the time, in hours
Let he equation which model this situation ⇒ d = a t + b
Where a and b are constant.
Let the gas station is the starting point
So, at gas station t = 0 , d = 20
∴ 20 = 0 * a + b ⇒ b = 20
When he reaches home 2 hours later notes that he has traveled 30 miles.
and with substituting with b = 20
∴ 30 = 2 * a + 20
2a = 30 - 20 = 10 ⇒ a = 10/2 = 5
∴ d = 5t + 20
The equations that can be used to model this situation <u>d = 5t + 20</u>
