(8a)(8b) = (8c)/(8d); multiply both sides by 8d to obtain (8a)(8b)(8d) = (8c); divide both sides by 8 to obtain (8a)(8b)d = c; divide both sides by (8a)(8b) to obtain
d = c/[(8c)(8b)].
8b = -65 so b = -8.125
6c you nerds out there and the next one is 6b,6a,7c,7b,7a,8c,8b,8a and so on
That's an equation in which b = -1
Absolute 4 is 4. The question is now "what is 4-8b absolute = 12. There is an "absolute" here operating on nothing. This is still true if you mean absolute(4-8b) absolute =12 so the question cannot be interpreted.
5b+6=32-8bSince -8b contains the variable to solve for, move it to the left-hand side of the equation by adding 8b to both sides.5b+6+8b=32Since 5b and 8b are like terms, add 8b to 5b to get 13b.13b+6=32Since 6 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 6 from both sides.13b=-6+32Add 32 to -6 to get 26.13b=26Divide each term in the equation by 13.(13b)/(13)=(26)/(13)Simplify the left-hand side of the equation by canceling the common terms.b=(26)/(13)Simplify the right-hand side of the equation by simplifying each term.b=2
Two equations, two unknownsFirst, multiply 3a + 2b = 70 by 4. This gives the equation 12a + 8b = 96. Next, subtract 4a + 8b = 70 from this equation. This result gives 8a = 26, which, solving for a, gives a = 3.25.Substitue the value of a into one of the original equations, which will give b = 7.125.Finally check your results by substituting the values of a and b into each equation.Answer:Given two equations 3a + 2b = 24 ------ (1) and 4a + 8b = 70 ------ (2) We have to solve this by using elimination method.Multiply the equation 3a + 2b = 24 by 4 on both the sides.We get 12a + 8b = 96 ---------- (3)Now, subtract the equation (2) from equation (3)12a + 8b = 96 ---------- (3)4a + 8b = 70 ---------- (2)--------------------------------(12a - 4a) + (8b - 8b) = (96 - 70)8a + 0 = 268a = 26a = 26/8a = 13/4 (Or) a = 3.25Substitute the value of a in the equation (2)4a + 8b = 70 ---------- (2)4(13/4) + 8b = 70.13 + 8b = 708b = 70 - 138b = 57b = 57/8 (Or) b = 7.125

8b = -65 so b = -8.125
8b = e - 12n, possibly.
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
5b2 = 8b therefore 5b =8 therefore b = 1.6
6c you nerds out there and the next one is 6b,6a,7c,7b,7a,8c,8b,8a and so on
What I would do is change the problem up. Instead of b-9b I would make it -(9b-b). It is still the same problem; you will multiply the number inside the parenthesis be -1. So start with 9b-b. That would equal 8b. So it would change from -(9b-b) to -(8b) so you multiply 8b by negative 1 (-1) to get the answer -8b. -8b is your answer. So b - 9b = -8b
What is the climate in the Gulf Coastal Plains answer: Subtropical, zone 8a 8b and 9. Humid and hot in the summer cool and windy in the winter.
That's an equation in which b = -1
