Answer:
Brand A is more expensive by .02 per ounce
Step-by-step explanation:
To find the cost per ounce, take the cost and divide by the number of ounces
Brand A
1.28/8 =.16 per ounce
Brand B
1.68/12 = .14 per ounce
The difference is .16-.14 = .02 per ounce
Answer:
g(N)=3 + 7n
80 = 3 + 7n
move the variable to the left hand side so
80 - 7n = 3
now do 3 - 80 to get -7n = -77
now divide both sides by -7 to get
n=11
2nd
p(x) = 4x
6= 4x
so swap the equations so its
4x = 6
next divide both sides by 4
x = 3/2 or 1.5
Step-by-step explanation:
-2a+4 because you have to distribute
Answer:
13
Step-by-step explanation:
4+(-3)-2*(-6)
Let us start from the left
2*(-6)= 2 times 6 , where we will have a negative sign on the result as + when multiplied by - gives - (negative)
2*(-6)=-12
4+(-3)-2*(-6) = 4+(-3)-(-12)
Now we open the bracket from the left. It the sign outside the bracket is negative the sign in the bracket will be changed
Hence
4+(-3)-(-12)= 4-3+12
Now -3 +12 we find the difference as the signs are opposite and then place the sign with the larger number
Hence -3+12=9
4-3+12=4+9 = 13
