rudy will buy 3 ivory silk lilac trees or 2 bur oak trees he wants to buy the trees that cost less wgat trees will hey buy how m

Nata [24]

i higly think that he should buy three ivory silk lilac trees instead of the 2 bur oak trees because...

the ivory silk lilac trees only cost 25$ and the cost for the bur oak tree is 35$.

so the lower priced one wouldn't cost you that much on your budget if you have one.besides the price for three or more is acctually less than what the normal cost so it would save you alot of money.

hope this helps!

Mary has twice as many pencils as she has pens. Tom borrows a pen. Now, Mary has ten less pens than pencils. How many pencils do

I am Lyosha [343]

X - the number of pencils
y - the number of pens

She has twice as many pencils as she has pens.
$x=2y$

Tom borrows a pen, so she has y-1 pens. Now she has ten less pens than pencils.
$x-10=y-1 \\
x=y-1+10 \\
x=y+9$

Set 2y and y+9 equal to each other:
$2y=y+9 \\
2y-y=9 \\
y=9$
She has 9 pens.
