Answer:
x = 
7
Step-by-step explanation:
= 49
can equal 7 or -7
7 x 7 = 49. -7 x -7 = 49
If you mean how far did you go you went 80 km
5x-4=4x+8
-4x. -4x
X-4=8
+4. +4
X=12
5(12)-4=4(12)+8
60-4=48+8
56=56
The answer should be 4. Take note of the pattern of unit digits of 2^n.
2^1 = 2
2^2 = 4
2^3 = 8
2^4 = 16
2^5 = 32
Every 4 powers, it rotates 2, 8, 6, 4. Since 2020 is divisible by 4, the answer is 4.
Answer:
25GB was used that month
Step-by-step explanation:
Here, we want to calculate the GB used for the month.
Since we have $59.99 for 20GB, then the extra that brought the bill to $75.99 must have been from the beyond charges.
The extra charges is thus $75.99 - $59.99 = $20
Now, since $4 is charged as extra and we have a total of $20, the number of extra GB is thus 20/4 = 5
So the total GB for that month is 20 + 5 = 25GB
