Answer:
The second equation is correct.
y=2.25x + 4
Step-by-step explanation:
We can systematically eliminate the others.
For equation 3 and 4, 6.5*2 and 12*x is already bigger than 8 of the first set of numbers.
For equation 1, 2*x+8.5 is also bigger than 8 from the first set.
Plugging in the values to equation 2, we always get the correct cost.
Step-by-step explanation:
The numerical expression is:
(36 + 14) / (2 * 5).
Answer:
a) 5(6) = 30
b) 3.5(6) = 21
c) 153
Step-by-step explanation:
c) 30 + 39 + 21 + 36 + 27 = 153
