Answer:
18/21 and 14/21
Step-by-step explanation:
just get the demomiters the same
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).
The answer is: x<12
Steps by steps
5(x+5)<85
Divide each term by 5 and simplify.
5(x+5)÷5<85÷5
Reduce the expression by cancelling the common factors.
x+5<85÷5
Divide 85 by 5.
x+5<17
Move all terms NOT containing "x" to the right side of the inequality.
Subtract 5 from both sides of the inequality.
x<-5+17
Add -5 and 17.
=x<12
