Answer: 48 stard
Step-by-step explanation:
12 stars = 30 balloons
? = 120 balloons
Solve
120/30 x 12 = 48
The solution to this inequality is 4 < x or x > 4.
In order to solve this, follow the steps to solving an equation with one variable. The steps are below for you.
2x + 8 < 5x - 4 ------> Subtract 2x from both sides
8 < 3x - 4 -----> Add 4 to both sides
12 < 3x -----> Divide both sides by 3
4 < x
To show equality with fractions both fractions should be converted to show their values with the same denominator then draw a picture of those fractions.
Remember that you can only compare fractions with the same denominator as is said with other operations dealing with fractions.
