Answer:
7/6
Step-by-step explanation:
Firstly we have to distribute it and write in this form
1/4*12x-1/4*5.6=0.5*3x+0.5*0.7
3x-1.4=1.5x+0.35 ( now that we have multiplied and simplified it we will combine like terms remember whenever you move it to the other side of equal signs it turns the opposite of the sign value eg positive to negative.
subtract 0.35 from both sides leaving the equations as 3x-1.75=1.5x
now we move 3x on other side to combine with 1.5x and 3x becomes negative
-1.75=1.5x-3x
-1.75= -1.5x (divide -1.5 from both sides
-1.75/-1.5=1.5x/-1.5
1.166666666666667=x
or 7/6 if you left the fraction as it is and didn't simplify further.

Answer: -31.72
Step-by-step explanation:
Answer:
200$
Step-by-step explanation:
In this case, we already know the ratio between the savings and the spendings and it's 3:5.
This means that for every 3$ saved, Sam spents 5$.
Then, we only need to do a simply rule of 3, to stablish the amount spended.
If:
120 ---------> 3
X ------------> 5
Solving for X, we have:
120/X = 3/5
X = 120 * 5 / 3
X = 600 / 3
X = 200$
If you want to verify that this calculation is correct, then do the ratio between 120 and 200. If the ratio is 3:5 is correct. Here's the demostration:
120/200 --->simplified by 10: 12/20 ------->simplified by 4: 3/5
