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 the value of a resistance if 20v drives 2a through it?
Simply divide the voltage by the current. This means you apply Ohm's Law.
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
