Answer:
Cost of 1 hamburger = $1.3
Step-by-step explanation:
Assume;
Cost of 1 hamburger = a
Cost of 1 French fries = b
On first trip
3a + 4b = 7.10......eq1
On second trip
2a + b = 3.40....eq2
From eq2 x 4
8a + 4b = 13.6....eq3
From eq3 - eq1
5a = 6.5
a = 1.3
Cost of 1 hamburger = $1.3

Step-by-step explanation:
Refer to file. Trying something different. Should be easier to read than text format and is easier than mathML.
Answer:
y =0
Step-by-step explanation:
From the equation;
8³ × 8⁻⁵×8^y = 8⁻²= 1/8²
From the laws of indices;
aⁿ×aⁿ = a^2n
Therefore;
8³ × 8⁻⁵×8^y = 8^(3+-5+y)
8^(-2+y) = 8^-2 ; but the bases are the same and thus the exponents are the same;
-2 + y = -2
y = 0
