Answer:
9
Step-by-step explanation:
2 raised by 3 = 8
4 * 2 = 8
8 + 8 = 16
16 - 7 = 9
Answer:
a. x = -2
Step-by-step explanation:
64ˣ = 16⁽ˣ⁻¹)
64 = 4³
16 = 4²
4³⁽ˣ⁾ = 4²⁽ˣ⁻¹)
4³ˣ = 4²ˣ⁻²
3x = 2x - 2
x = -2
Answer:
Total distance:
- d=11/15 miles or 0.73 miles
Step-by-step explanation:
- Alison walks 2/5 miles from her house to the mailbox.
- Then she walks 1/3 mile to the bus stop.
Thus, the total distance can be calculated by adding the miles
i.e.

LCM of 5,3 is 15



miles
Thus,
Total distance:
- d=11/15 miles or 0.73 miles
First subtract 10 from both sides:
37 -10 = 6x + 10 -10
27 = 6x
Then divide both sides by 6
27 ÷ 6 = 6x ÷ 6
9/2 or 4.5 = x
