Answer:
(D) Divide the first equation,
, by 2.
Step-by-step explanation:
Given:

We need to find the operation performed on equation so as to get resultant equation as:


From Above we can see that there is no change in equation 2 with respect to resultant equation.
Also Resultant equation is simplified form of equation 1.
Simplifying equation 1 we get;

We can see that 2 is the common multiple on both side.
Hence we will divide equation 1 with 2 we get

which is the resultant equation.
Hence (D) Divide the first equation,
, by 2 is the correct option.
Answer:
4:1 or 4/1
Step-by-step explanation:
Original surface area: Each side is 1 * 1 = 1 and there are 6 sides, so 1 * 6 = 6.
New surface area: Each side is 2*2 = 4, and there are 6 sides, so 4 * 6 = 24
The ratio would be 24:6, or 4:1. As a fraction, this would be 4/1
2+1.25f=10-2.75f Add the variables
2+4f=10 isolate the variable
4f=8
f=2
