There are 66 elephants in the safari.
Solution:
The number 88 refers to both elephants and giraffes that are in the safari. We know that the number of elephants is thrice the number of giraffes. So we can let x be the number of giraffes and 3x be the number of elephants.
We will then come up with the following equation:
3x + x = 88
Then, just add the two variables, and continue the operation.
4x = 88
x = 88/4
x = 22
Now we know that there are 22 giraffes in the safari. So 3x, or 3(22) = 66. There are 66 elephants in the safari.
Hello,
Diagonals of a rectangle must have the same measure.
You don't need to know the dimension of the diagonal but only if they are equals.
(√(90²+48²)=102 (yd))
Answer:
The average number of people per car is 2.91
Step-by-step explanation:
To find the average number of people per car, we divide the total number of people by the total number of cars.
We have that:
57 cars had 4 people
61 cars had 2 people
9 cars had 1 person,
5 cars had 5 people.
Number of people:
57*4 + 61*2 + 9*1 + 5*5 = 384
Number of cars:
57 + 61 + 9 + 5 = 132
Average:
384/132 = 2.91
The average number of people per car is 2.91

x is equal to 27.
In order to find the value of x, you have to use the average formula and solve for the missing variable. The mean formula is all of the numbers added together divided by the number of inputs.
(inputs added)/(number of inputs) = Average
(2 + 7 + x)/3 = 12 ----> Multiply by 3
9 + x = 36 ----> Subtract 9
x = 27
