How do you solve for the variable b in 2a plus 2b equals c?
2a + 2b = c subtract 2a from both sides 2a - 2a + 2b = c - 2a 2b = c - 2a divide both sides by 2 (2/2)b = (c - 2a)/2 b = (c - 2a)/2 --------------------
If 24 equals 2a x 3 what is the value of a?
2a x 3 = 24= 6a = 24(divide both sides by 6)a = 4
What is 2a - 3 -5?
Start with simplifying: 2a + -3 = 5 and reordering: -3 + 2a = 5. Then add '3' to each side of the equation: -3 + 3 + 2a = 5 + 3 and you get 2a = 8 once all like terms are combined. The last step is to divide both sides by 2 and you get the answer, which is a = 4.
What is the solution of a 5a-5 equals 7 plus 2a?
5a - 5 = 7 + 2a ( subtract 2a from both sides) 3a - 5 = 7 (add 5 to both sides) 3a = 12 ( divide both sides by 3) a = 4
What is 2a times 3?
Since the question is 3(2a), then just write it out. 3(2a) is 2a+2a+2a or 6a.
How do you solve for the variable b in 2a plus 2b equals c?
2a + 2b = c subtract 2a from both sides 2a - 2a + 2b = c - 2a 2b = c - 2a divide both sides by 2 (2/2)b = (c - 2a)/2 b = (c - 2a)/2 --------------------
If 24 equals 2a x 3 what is the value of a?
2a x 3 = 24= 6a = 24(divide both sides by 6)a = 4
What is 2a - 3 -5?
Start with simplifying: 2a + -3 = 5 and reordering: -3 + 2a = 5. Then add '3' to each side of the equation: -3 + 3 + 2a = 5 + 3 and you get 2a = 8 once all like terms are combined. The last step is to divide both sides by 2 and you get the answer, which is a = 4.
What is -2a - 9 = 39?
This is very easy questions lets solve it -2a - 9 = 39? Add both site 9 -2a - 9 +9= 39+9 Now Simplyfy -2a - 9 +9= 39+9 -2a= 48 devide both side with same factors -2a/-2= 48/-2 a= -24
What is the solution of a 5a-5 equals 7 plus 2a?
5a - 5 = 7 + 2a ( subtract 2a from both sides) 3a - 5 = 7 (add 5 to both sides) 3a = 12 ( divide both sides by 3) a = 4
How do you solve 6a plus 1 equals 2a plus 25?
6a+1=2a+25 Subtract 2a from both sides 4a+1=25 Subtract 1 from both sides 4a=24 Divide both sides by 4 a=6 That is your final answer.
Which number is a divisible by LETTER A?
You divide numbers by numbers, you don't divide letters. If you are talking about algebra - where letters stand for numbers - then the answer would depend on the value of the letter a. "a" multiplied by any integer is divisible by a, for example: 0a = 0, 1a = a, 2a, 3a, 4a, 5a, -a, -2a, -3a, etc.
What does a equal 2a-15 equals -1?
Do the problem like this: 2a - 15 = -1 Add 15 to both sides: 2a = (-1) + 15 Simplify 2a = 14 Divide by 2 to get the variable by itself: a = 7 Now, check the problem: 2(7) - 15 = -1 14 - 15 = -1 This is true, so a = 7 is a good solution.
What is 2a times 3?
Since the question is 3(2a), then just write it out. 3(2a) is 2a+2a+2a or 6a.
Where did the quadratic formula come from?
The quadratic formula originated from the concept of completing the square. let's take ax2 + bx + c = 0. To complete the square, solve for x. Subtract c. ax2 + bx = -c. Then divide by a [notice- if there is no a value, then a=1]. x2 + bx/a = -c/a. Add (b/2a)2 to both sides. x2 + bx/a + b2/4a2 = -c/a + b2/4a2 Factor/Reformat. (x + b/2a)2 = (b2-4ac) / 4a2 (x + b/2a)2 = [(b2-4ac) / 2a]2 Square-root both sides. x + b/2a = ± √(b2-4ac) / 2a Subtract b/2a. x = -b/2a ± √(b2-4ac) / 2a Combine terms. x = [-b ± √(b2-4ac)] / 2a
