Dan and Omar each ran every day as part of an excercise routine. Dan ran 4 miles each day for x days. Omar ran 6 miles each day
Gnom [1K]
We can represent the Omar's miles by 6y or miles ran per day times number of days. In this case, Dan's miles are represented as 4x.

They told us that Dan ran more miles than Omar. We can write down that as Dan's miles > Omar's miles.

When we convert that into the variable form we get: 4x > 6y

What's the value of 3y2 + 2z when y = 4 z= -7
Delicious77 [7]
Y= 4
z= -7

Substitute the given values above in for each variable in the expression below.


= 3y^2 + 2z

= 3(4)^2 + 2(-7)
using order of operations, square 4 before multiplying (PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction)

= 3(16) + (-14)
a positive times negative is negative

= 48 - 14

= 34


ANSWER: 34

Hope this helps! :)
