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).
Answer:
Many reasons
Step-by-step explanation:
Is there an asymptote?
Is there a whole?
Is it a vertical or horizontal line?
What's the specific function?
You can you 72 which would make 2/8 18/72 and 3/9 24/72 which makes the sum 42/72.
Since there are 4 quarts in a gallon and we have 28 quarts we would have 7 gallons.
<u>The answer is 7. </u>
B :) open circle means inequality and it needs to be at least 3 so the line has to increase, meaning the arrow is going right.
