Answer:
31.5 or 63/2
Step-by-step explanation:
to do this, first you need to transform the <u>mixed number</u> <em>(3 1/2)</em> into an <u>improper fraction</u>, to get 7/2.
then you just multiply 9 by 7/2
9/1 (7/2)
63/2 = 31.5
<em>both of the answers in bold are correct</em>
X=
with x+6=10
yo try to move everything to the opposite side of the X.
so:
adding equals subtracting. + = -
subtracting equals adding. - = +
dividing equals multiplaying. ÷ = ×
and multiplaying equals to dibidion. × = ÷
77 is a multiple of 11, as i'm sure you know--the double numbers like 22 and 55, one of the factors are always 11.
77 is factored down into 11 and 7--which, when you add those, luckily equal 18.
(x + 11)(x + 7) is your factorization.
