Step-by-step explanation:
No of blue marbles = 7
No of green marbles = 4
No of red marbles = 6
No of yellow marbles = 8
Total marbles = 25
Probability of green marble = 4/ 25
This is must be 3.7 you have to share and, to share you supposed to divided together
Answer:
12 football tickets for $72
Step-by-step explanation:
you do 72 divided by 12 and you get 6.
X=area of Sahara.
y=area of the Gobi Desert.
We suggest this system equations:
x+y=4000000
x=7y
solve by susbstitution method.
(7y)+y=4,000,000
8y=4,000,000
y=4,000,000 / 8=500,000
x=7y
x=7(500,000)=3,500,000
The area of Sahara=3,500,00 miles².
The area of the Gobi Desert=500,000 miles²
To check:
Te sum of their areas is : 3,500,000 miles²+500,000 miles²=4,000,000 miles²
Te area of sahara (3,500,000 miles²) is 7 times the area of the Gobi Desert (7*500,000 miles²=3,500,000 miles²).
