Answer:
-7
Step-by-step explanation:
it is possible because x is just a letter representing the unknown nos
The first number would be 3×5=15.
Another number could have different values. it could be
4=2×2
12=2×2×3
20=2×2×5
60=2×2×3×5
I=prt
I interest earned
P principle 4000
R interest rate 0.095
T time270/365
I=4,000×0.095×(270÷365)
I=281.10
Three plus the product of four times twelve
Let
x-------> bags of <span>popcorn
</span>y-------> bags of hotdogs
we know that
2.50x+3y=200-------> equation 1
x=2y--------> equation 2
substitute 2 in 1
2.50*[2y]+3y=200--------> 5y+3y=200------> 8y=200-----> y=200/8
y=25
x=2y-----> x=2*25-----> x=50
the answer is
50 bags of popcorn
25 bags of hotdogs<span />
