Answer:
The answer to this question can be defined as follows:
In option 1, She buys 4 memory cards.
In option 2, The cost of memory is $40
Step-by-step explanation:
Given:
Available space is = 105 GB
required space = 1000 GB
256 GB memory cost $10.
Find needed memory:
= 1000 GB - 105 GB
= 895 GB
∴ the available memory is 256 GB.
∵ 256 × 4 = 1024 GB
The total memory she have = 1024 + 105 = 1129 GB
And she needs to buy 4 memory cards.
The cost of the four memory cards is= 4 ×10 = $40.
Check picture below, radius = r = 15, thus
So for each day, Tessa ran 2.25 miles. So, multiply 2.25 miles by the number of days, which is 14, to get the total number of miles ran.
2.25 x 14 = 31.5 miles
8x-2=3x+12.25
First, get x on one side by subtracting 3 on both sides->
5x-2=12.25
Then, add 2 on both sides
5x= 14.25
Finally, isolate x by dividing both sides by 5
X=2.85
