Answer:
<em>1,860</em>
Step-by-step explanation:
FIRST:
we divide 124 by 4 because in 4 minutes he can type 124 words, and we need to figure out how many he can type in a minute.
124 divided by 4 is 31. (they can type 31 wpm)
NEXT: now we know they can type 31 wpm, we need to multiply that number by 60 because there are 60 minutes in an hour.
31 x 60 = 1,860
therefore, they can type 1860 words per hour
hope i helped have a great day/night! :'')
Answer:
2 or -2
Step-by-step explanation:
If x² - 8x = -12
Step 1
We find x by solving
x² - 8x = -12
We equate to zero
x² - 8x + 12 = 0
We factorise
x² - 6x - 2x + 12 = 0
x(x - 6) -2(x - 6) = 0
(x - 6) (x - 2) = 0
x - 6 = 0, x = 6
x - 2 = 0, x = 2
x = 6 or 2
Step 2
What is x - 4?
When x = 6
= 6 - 4 = 2
When x = 2
= 2 - 4 = -2
Therefore, x - 4 = 2 or -2
