The first thing to do is to substitute the b and c. The equation will look like this, a+3a+5a=180. Then you must add the a's all together because they are all the same, remember that "a" represents 1. It will look like this in plain 1 + 3 + 5. Then the equation is 9a = 180. to get the "a" you must eliminate or divide the equation into 9 and it will look like this, <u>9a</u> = <u>180</u> Then the answer will be a = 20
9 9
Answer:
1/98
Step-by-step explanation:
Step 1: Translate statement into equation.
Step 2: Multiply both sides by 7x.
Step 3: Divide both sides by 98.
Step 4: Check if solution is correct.
Therefore, the answer is 1/98.
The answer for Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth is letter d
Answer:
20/100=1/5
Step-by-step explanation:
find the gradient of the line to find the fraction
the line is 20 units high so the line starts and stops subtracting equals 20 and the line is 100 units long to get the gradient you find the rise over the run
