Answer: 80
Step-by-step explanation:
x.3/2 = 120
x = 120.2/3
x=80
Number of blue marbles = n
number of green marbles = 3n+4
n+3n+4=36
4n+4=36
4n=32
n=8
sub n=8 into 3n+4
=3(8)+4
=24+4
=28
therefore there are 28 green marbles
Answer:
Step-by-step explanation:
y = 2x - 3
y = -x
-x = 2x - 3
-x - 2x = -3
-3x = -3
x = -3/-3
x = 1
y = -x
y = -1
solution is : (1,-1) <==
Answer:
The Giraffe has a weight which is 3 times that of the Gorilla
Step-by-step explanation:
Here, we are interested in calculating the number of ways in which the giraffe’s weight is greater than the gorillas
From the question, the weight of the giraffe is 4.5 * 10^3 pounds
The weight of the Gorilla is 150 pounds
So, the number of ways it will be greater will be;
(4.5 * 10^3)/150 = 4500/150 = 30 times
The Giraffe is 3 times the weight of the Gorilla
