What is the slope of the line 3x-7y=11

Tom [10]

Slope intercept form is y=mx+b where m=slope and b=yintercept so

3x-7y=11
add 7y to both sideds
3x=11+7y
subtract 11 from both sides
3x-11=7y
divide both sides by 7
3/7x-11/7=y
y=3/7x-11/7

slope is 3/7

15.12 is what percent of 12?

Llana [10]

Answer:

Step-by-step explanation:

$\bold{METHOD\ 1}\\\\\begin{array}{ccc}15.12&-&p\%\\\\12&-&100\%\end{array}\qquad\text{cross multiply}\\\\\\12p=(15.12)(100)\\12p=1512\qquad\text{divide both sides by 12}\\p=126$

$\bold{METHOD\ 2}\\\\p\%=\dfrac{p}{100}\\\\p\%\ of\ 12\ is\ equal\ to\ 15.12:\\\\\dfrac{p}{100}\cdot12=15.12\\\\\dfrac{12p}{100}=15.12\qquad\text{multiply both sides by 100}\\\\12p=1512\qquad\text{divide both sides by 12}\\\\p=126$
