box one
box three
box four
box two is incorrect because 0.80/100 x 400 is 3.2
and we are looking for the common denominator of 320 :)
how do i know the common denominator is 320? it's is 80% of 400!
i hope this helps
<em>a=b+24</em>
<em>c=4a</em>
<em>b=a-24</em>
a+b+c=180
<u>sub in a,b and c into a+b+c=180</u>
b+24+4a+a-24=180
b+5a=180
sub a=b+24
b+5(b+24)=180
b+5b+120=180
6b=180-120
6b=60
b=10
Book B has 10 pages
Answer:
A
Step-by-step explanation:
Slope-intercept form: y=mx+b
2x+3y = 12
3y = 12-2x
y = (12-2x)/3
y = 4-2/3x
Here we can see that the slope is -2/3 and y-intercept 4. We already got the answer so we dont need to try the other options.
Answer =yes, the residuals would tend to be one sided
