n=4
Step-by-step explanation:
To solve combine your like terms.
You can start by adding 0.8 to both sides and subtracting 0.7n from both sides.
Next, divide both sides by 0.7 to isolate for n.

Answer:
4+x>13
x>9
Step-by-step explanation:
This statement represents an inequality. To solve for the missing number first write out the inequality algebrically.
"Four more" implies that 4 is being added to the number. Another way to "a number" is to use the variable, x. So, the left side of the inequality is 4+x. Then, it says that this is "more than" 13. Thus, the greater than sign, >, should be used. This means that the final inequality is 4+x>13.
Next, you can solve the inequality by subtracting 4 from both sides. This gives x>9.
Answer:
93%
Step-by-step explanation:
1 + 3 + 21 + 35 = 60 = 100%
21 + 35 = 56 = x%
60 = 100%
56 = x%
60x = 56 * 100
x = 56* 100 / 60
x = 2*23*2*2*5*5 / 2*2*3*5
x = 23*2*5/3
x = 93%
