394.6 divided by 9 using compatible numbers to estimate the quotient?
2 answers:
So you could round 9 to 10 and multiply
this is easier since multiplying by 10 just moves the decimal point to the right so
394.6 times 10=3496
Round 396.6 to 396, because 396/9=44, making a whole number. Hope this helps!!

30/50
Step-by-step explanation:
because there is a y distance of 30 and x distance of 50 from point to point.
No as complementary angles add up to whisk 180 degrees, however supplementary angle would be true for this question
41+0.10x = 31+0.15x
10 +0.10x=0.15x
10=0.05x
x=10/.05
x= 200 text messages
check 200*0.10 = 20 +41 =61
200*0.15 = 30+31 = 61
they equal each other so number of texts is 200
