How do you solve 5x-2=8?

Mathematics

Answer:

x = 2

Step-by-step explanation:

5x - 2 = 8

get rid of 2 to get x by itself on the left side

5x - 2 + 2 = 8 + 2 (whatever u do to one side do to the other)

5x = 10

divide to get 1x (divide both sides by 5)

x = 10

Answer:

x=2

Step-by-step explanation:

5×2=10-2=8

You subtract add two to both sides, giving you 5x=10

Divide the 10 by 5 and you get 2.

In order to complete a reading assignment on time, Terry planned to read 90 pages per day. However, she read only 75 pages per d
Aleonysh [2.5K]

Say Terry read at the rate of 75 pages per day for d days. 

Now, in d days she read 75d pages, and since after that 690 pages were left, then the number of pages in the book is 75d+690.

Next, we also know that she had d+6 days for the assignment. Since Terry planned to read 90 pages per day for this number of days, then the number of pages in book is also equal to 90(d+6).

So, we have that 75d+690 = 90(d+6). Solving the linear equation, we get d = 10.

Thus, the total number of days that she has to complete the assignment on time is d+6 or 10 + 6 = 16 days.

Find f(k - 1) when f(x) = 5x^2+ 4x – 5.
bekas [8.4K]

Plug in k-1 to each x in the function.

f(k-1)=5(k-1)^2+4(k-1)-5

f(k-1)=5(k^2-2k+1)+4k-4-5

f(k-1)=5k^2-10k+5+4k-4-5

f(k-1)=5k^2-6k-4

Hope this helps.

頑張って!
