Answer: One solution
Step-by-step explanation:
Given
-5x-8=8
Add 8 on both sides
-5x-8+8=8+8
-5x=16
Divide -5 on both sides
-5x/-5=16/-5
x=-3.2
Therefore, it has one solution

Answer:
899.5
Step-by-step explanation:
We're given the Arithmetic Progression <em>-24, -4, 16, 36 ...</em> .
We know that a term in an AP is generally represented as:

where,
- a = the first term in the sequence
- n = the number of the term/number of terms
- d = difference between two terms
We need to find
.
From the given progression, we have:
- a = -24
- n = 23
- d = (-24 - (-4) = -20
Using these in the formula,

Therefore, the 23rd term in the AP is -464.

Answer:
B
Step-by-step explanation:
-6 10n to the 5 11n to the 3
you put the ones that are alike to gether. so -3 and -3 together and 5n to the 3rd and 6n to the third together and 3n to the fifth and 7n to the fifth together
