Plugging the values if x and y the last option is correct
3x-y=4
310=62% of x
let x b the total number of pages
x=500 so total number of pages are 500.
and rest has no picture=500-310=190
<span> pythagorean theorem formula= </span> a^{2}+ b^{2}= c^{2}
I have the same math with is Go Math and the pattern is:
38×1=38
38×0.1=3.8
38×0.01=0.38
