My father taught me a method that I call, 'throwing some thing over the wall'. There is a sample equation for the first picture that shows you how it works. It's a great way to help isolate the variable and I hope that it works for you. The second picture contains the answers I got through the use of this method. I'm sorry for the messy handwriting; I was on a bus.
Answer:
1
Step-by-step explanation:
5/7+2/7 add the numerator to equal 7/7 simplify to 1/1 equals 1
Answer:
50 million
Step-by-step explanation:
current value: c
initial value : i
c = 1.2 × i
x - i = 10
10 + i = 1.2 × i
0.2 ×i = 10
i = 50
Answer: x=3
Step-by-step explanation:
Move all x terms to the same side- x/2-x/3-1/2
Multiply to get common denominator- 3x/6-2x/6=1/2
Subtract 3x/6 and 2x/6 - x/6=1/2
Simplify - x=3
Answer: 48÷4 = g
Step-by-step explanation:
Here is the complete question:
Dylan scored a total of 48 points in first 4 games of the basketball season. Which equation can be used to find g, the average number of points he scores per game?
a. 48÷4=g
b. 4÷48=g
c. g÷4=g
d. 4÷g=48
The average number of points Dylan scores per game which has been represented by g will be the total points scored divided by the number of game played. This will be:
g = total point scored ÷ number of games played
g = 48 ÷ 4
Therefore, option A is the right answer.
