Answer:
8 bags of rye & bluegrass mix
10 bags of bluegrass
Step-by-step explanation:
RB = bags of rye & bluegrass mix
B = bags of bluegrass
348B + 255RB = 5334
RB+B = 18 then RB = 18-B
substitute for RB
348B + 255(18-B) = 5334
348B + 4590 - 255B = 5334
reduce
93B = 744
B = 8
RB = 10
Answer:
It is not a whole number.
Step-by-step explanation:
5/4 is equals to 1.25
Therefore it is still a decimal and a fraction, NOT a whole number
Answer:
Step-by-step explanation:
Four
Start by trying to understand what f(x) means. First of all it is the same thing as y in the equation given in question 4. It is a shorthand that tells you that you put an x in wherever you see an x on the right.
More important, it tells you what to put in for x on the right.
f(z) would tell you to put z in for x anywhere there is an x on the right.
f(z)=2z+1. It is just a shorthand to tell you what to do on the right.
f(2) means put a 2 in for the x on the right. Read all of this carefully. You need to know it.
f(2) = 2(2) + 1
f(2) = 4 + 1
f(2) = 5
=================
Five
f(x) = -x - 5 The minus 4 is not going to change what you do.
f(-4) = -(-4) - 5 Wherever you see an x you put in a minus 4
f(-4) = 4 - 5
f(-4) = - 1
======================
Just so you know, consider a more complicated example
f(x) = 20x^3 + 7x^2 + 4x + 19
Where ever you see an x put in 2
f(2) = 20*(2^3) + 7*(2^2) + 4(2) + 19
f(2) = 20*8 + 7*4 + 4*2 + 19
f(2) = 160 + 28 + 8 + 19
f(2) = 215
Note x can be anything the question tells you it is.
f(5) means put a 5 in for every x.
It is B because have you do 160+77-x=180 you would add the like terms 160+77=237 and then subtract 180 from 237 and you get 57 for x and when you plug that in 160+77-57 77-57=20 and 20 plus 160 is 180 so The answer is B)No of these
29.75 rounds to 30 and 30 times 3 is 90. So about $90 for 3 weeks
