3a plus 2b equals 4 and b equals 7?
3a + 2b = 4If b = 7, then3a + 2(7) = 43a + 14 = 4Subtract 14 from each side:3a = -10Divide each side by 3:a = -10/3
How do you evaluate the variable expression 3a plus 2b?
You need values for a and b, then you multiply a by 3, b by 2 and add your answers.
What is the value of 3a plus 2b when a equals 6 and b equals 5?
3 times 6 is 18 2 times 5 is 10 18 plus 10 is 28
How do you solve 5b-7 equals 2b plus 5?
5b - 7 = 2b +55b-2b-7=2b -2b +5 subtract 2b from each side to get b on one side3b-7=53b-7+7 = 5+7 now add 7 to both sides to get the numbers on one side3b = 123b/3 = 12/3 finally divide both sides by 3 to solve for bb = 4
What is the whole cube of a-b?
(a - b)^3 = a^3 - 3a^2b + 3ab^2 - b^3.
Solve for the variable specified. Assume domains include only values that give nonzero denominators.3a plus 2b equals c for a?
3a + 2b = c (find a in terms of b and c)3a +2b -2b = c - 2b3a = c - 2b3a/3 = (c - 2b)/3a = (c - 2b)/3In order to find the value of a, you can give any values to b, and c (except a zero value).
Find the value of 3a plus 2b when a equals 6 and b equals 5?
3a + 2b = (3*6) + (2*5) = 18 + 10 = 283a+2b= (3x6)+(2x5)= 18+10=28
3a plus 2b equals 4 and b equals 7?
3a + 2b = 4If b = 7, then3a + 2(7) = 43a + 14 = 4Subtract 14 from each side:3a = -10Divide each side by 3:a = -10/3
What is 3a plus 2b?
3a + 2b is an expression in algebra. If you make 3a + 2b equal to something then you can find the values of "a" and "b" Lets say you make 3a + 2b equal to 23 3a + 2b = 23 Now find "a" and "b" to make this equation true... 3(5) + 2(4) = 23 15 + 8 = 23 23 = 23 Correct So in this case a=5 and b=4
How to simplify 4 a-b plus 3 a-b?
7
How do you solve 3a plus 4 equals 4a-3?
3a + 4 = 4a - 3 4 = a -3 (subtract 3a from each side) 7 = a (add 3 to both sides) a = 7
How do you evaluate the variable expression 3a plus 2b?
You need values for a and b, then you multiply a by 3, b by 2 and add your answers.
What is 3a x 2b x 5a simplified?
what is 5a x 3 x 2b
What is the value of 3a plus 2b when a equals 6 and b equals 5?
3 times 6 is 18 2 times 5 is 10 18 plus 10 is 28
How do you solve 5b-7 equals 2b plus 5?
5b - 7 = 2b +55b-2b-7=2b -2b +5 subtract 2b from each side to get b on one side3b-7=53b-7+7 = 5+7 now add 7 to both sides to get the numbers on one side3b = 123b/3 = 12/3 finally divide both sides by 3 to solve for bb = 4
