What is the answers to -7 ( a + b - 5 ) + 8 ( -3a +2b ) + b ( 7 + 3 )
3a + 2b = 4If b = 7, then3a + 2(7) = 43a + 14 = 4Subtract 14 from each side:3a = -10Divide each side by 3:a = -10/3
The expression (3a + 2b) is already in its simplest form, as it cannot be combined further without specific values for (a) and (b). It represents a linear combination of the variables (a) and (b) with coefficients 3 and 2, respectively.
The expression (3a \times a \times b) can be simplified by multiplying the coefficients and combining like terms. This results in (3a^2b), where (3) is the coefficient, (a) is squared, and (b) remains as is. Thus, the final answer is (3a^2b).
To simplify the expression ( 6a - 2b + 3(a - b) ), first distribute the ( 3 ) in the term ( 3(a - b) ), which gives ( 3a - 3b ). Combining like terms, we have ( 6a + 3a - 2b - 3b ), resulting in ( 9a - 5b ). Thus, the simplified expression is ( 9a - 5b ).
3 times 6 is 18 2 times 5 is 10 18 plus 10 is 28
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).
3a + 2b = (3*6) + (2*5) = 18 + 10 = 283a+2b= (3x6)+(2x5)= 18+10=28
3a + 2b = 4If b = 7, then3a + 2(7) = 43a + 14 = 4Subtract 14 from each side:3a = -10Divide each side by 3:a = -10/3
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
7
3a + 4 = 4a - 3 4 = a -3 (subtract 3a from each side) 7 = a (add 3 to both sides) a = 7
To simplify the expression ( 6a - 2b + 3(a - b) ), first distribute the ( 3 ) in the term ( 3(a - b) ), which gives ( 3a - 3b ). Combining like terms, we have ( 6a + 3a - 2b - 3b ), resulting in ( 9a - 5b ). Thus, the simplified expression is ( 9a - 5b ).
what is 5a x 3 x 2b
3 times 6 is 18 2 times 5 is 10 18 plus 10 is 28
(a - b)^3 = a^3 - 3a^2b + 3ab^2 - b^3
(a - b)^3 = a^3 - 3a^2b + 3ab^2 - b^3.
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
