What’s the correct answer??
zhuklara [117]

So cos(60) = a / 12

Solve for x. <br><br><br> 7x/2+5=8
finlep [7]

Answer:

x=6/7

Step-by-step explanation:

7x÷2+5=8

divide by 2 on both sides:

7x/2+5=8(it's a fraction)

subtract 5 on both sides

7x÷2=3

multiply 2 on both sides

7x=6

divide by seven on both sides

x=6/7

hope this was helpful and the instructions were clear enough!

How would you solve 4n-2n=4?
Nezavi [6.7K]

Answer:

n = 2

Explanation:

Simplify both sides of the equation

4n − 2n = 4

4n + −2n = 4

(4n + −2n) = 4 (Combine Like Terms)

2n = 4

2n = 4

Divide both sides by 2

2n / 2 = 4 / 2

n = 2
