How do you solve 5b squared equals 8b?
5b2 = 8b therefore 5b =8 therefore b = 1.6
What is 4a plus 8b - 12c?
They are 3 terms of an algebraic expression
What is 8b minus 4b?
8b - 4b = 4b
4 x b-1 plus -4 plus 4b?
Well if it is worded right then 4xb-1+(-4)+4b=4b-1-4+4b=4b+4b-1-4=8b-5
What is 6ab-8b?
b(6a-8) if you are factoring
What is 2b-5 equals 8b plus 1?
That's an equation in which b = -1
4a - 2b plus 6a - 8b?
10a - 10 b
How do you factor 4a plus 8b-16c?
4(a + 2b - 4c)
What is 8b plus 20 in factored form?
4(2b+5)
8b plus 11-3b equals 2b plus 2?
Amazing! Exactly the same question was posted here on WikiAnswerslast September 23. What an incredible coincidence!8b + 11 - 3b = 2b + 2That 8b on the left side can be combined with the -3b to make 5b .5b + 11 = 2b + 2Subtract 2b from each side:3b + 11 = 2Subtract 11 from each side:3b = -9Divide each side by 3:b = -3(That's the same answer they got last September.)
What is equivalent to e equals 8b plus 12n?
8b = e - 12n, possibly.
What is the answer of 23 plus 8b equals -42?
8b = -65 so b = -8.125
If 3a plus 2b equals 24 and 4a plus 8b equals 70 how do you solve for a and b using the elimination method?
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
6a plus 7b - 4a - 8b equals?
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
Factor 6ab - 8b?
-2
What is b if 7b plus 16 equals 5b plus 24?
7b + 16 = 5b + 247b - 5b = 24 - 162b = 8b = 4
How do you solve 2a to the power of 8b-5 if a to the power of 2b equals 5?
If you mean 2a8b - 5 = x and a2b = 5, then: 2(54) - 5 = x x = 1350 - 5 x = 1345
