Answer: for the first one it is 22 percent

Step-by-step explanation: first I found out that 14.08 is In-between 64 and 78.08 . Then I devided 14.08 by 64 so I got 0.22 then i made that a percentage by multiplying it by 10. So the answer is 22 percent. Please mark me brainiest.

I did it on the other one but here is the full explanation

The second one is $25 because 23.36 times 7% equals 1.36 then add 23.36 and 1.36 and you get $25

olasank [31]
If 40% of students prefer keyboarding, 40/100*40=16 students like it best. If the remaining students prefer English, then 40-16=24 students like English best. Since 24 is more than 16, most students prefer English.

____ [38]
It wants it to be in slope-intercept form.

y=mx+b

We have to first find the slope and plug it into point-slope form.

y-y1=m(x-x1)

Find the slope of the second line. (I did this one first on accident)

Rise/run= 3/1= 3 The slope is 3. Plug that in along with the point (0,3)

y-3=3(x-0)
y-3=3x

Add 3 to the other side.

y= 3x +3 <- <em>for the second line</em><em>
</em>
Now, the second.

rise/run= 1/2= .5 Use point (6,0)

y-0=.5(x-6)
y= .5x-3 

y=.5x-3 <- for the first line

I hope this helps!

Vaselesa [24]
I believe you ment to say sale price but I hope this helps you understand your question. The original price was 1200, and if it were 5/6 on sale (this method works for all questions like this) you would do 1200 ÷ 6 = 200 x 5 = $1000.
