How do you solve the equation 8a plus 4a equals 144?
8a+4a=144 12a=144 12a/12=144/12 A=144
Solve this equation using addition method 4a subtract 5b equals 7 and 4a plus 5b equals 17?
Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1
If 5a 4a-1 equals 9a-4 what is the method used to get that answer?
Because of limitations with the question software, some symbols cannot be rendered, so we don't know what operation there is between the 5a and the 4a-1. Assuming a plus sign produces an inconsistent equation. But if we assume a / (slash) for division, we get a quadratic equation that produces some reasonable roots, so here's what I think the question is: Can you solve the following equation for a: 5a/(4a-1) = 9a-4 ? Yes you can! Multiply both sides of the equation by 4a-1. This gives you: 5a = (9a-4)(4a-1) Expand the right side, which gives you 5a = 36a2 -9a -16a + 4 Subtract 5a from both sides and group similar terms: 0 = 36a2 -30a + 4 Now, use the quadratic formula to solve for a(left to the student): a1 = 2/3; a2 = 1/6
How do you solve 9 equals 4a plus 13?
9=4a+13 9-13=4a -4=4a -4/4=a -1=a a=-1
What is the solution set of the equation 4a plus 6 -4a equals -10?
4a + 6 - 4a = -10 Combining like terms: 6 = -10 or 4 = 0 which is FALSE. So the solution set is empty.
Solve the following equation 2A3 equals 8 plus 4A?
Solve the following equation for A : 2A/3 = 8 + 4A
Solve the following equation for A2A3 equals 8 plus 4A?
2a^3=8+4a2a^3-4a-8=0 a^3-2a-4=0 It occurred to me just now by looking at the equation that a=2 would work. And it does. So that's your answer.
Solve the following equation for A 2adivided by 3 equals 8 plus 4a?
2a/3=8+4a2a=3(8+4a) 2a=24+12a -10a=24 a=-24/10 a=-12/5
How do you solve this equation 4a-2.1 equals 9a plus 5.4?
4a - 2.1 = 9a + 5.4 4a - 9a = 5.4 +2.1 -5a = 7.5 -a = 1.5 a = -1.5
How do you solve the equation 8a plus 4a equals 144?
8a+4a=144 12a=144 12a/12=144/12 A=144
Find the sulotion set of 4a2-16a equals 0?
The given equation is 4a^2 - 16a = 0. Factoring out a common factor of 4a, we get 4a(a - 4) = 0. This equation is satisfied when either 4a = 0 or (a - 4) = 0. Solving these, we find that the solution set is a = 0 and a = 4.
4a - 5b equals 7 4a plus 5b equals 17?
4a - 5b = 74a +5b = 17From the first equation:4a = 7 + 5bsubstitute this value in the second equation:7 + 5b + 5b = 177 + 10b = 1710b = 10b = 1Now,solve for a :4a - 5(1) = 74a = 7 + 54a = 12a = 3
Solve the equation a plus 4 equals 10?
a + 4 = 10(a + 4) - 4 = 10 - 4a = 6
Solve this equation using addition method 4a subtract 5b equals 7 and 4a plus 5b equals 17?
Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1
How do you solve 4a - 9 equals 27?
4a - 9 = 27 4a = 36 a = 9
Solve the inequality 4a plus 9-6a -5?
Without an inequality sign it can't be considered to be an equation but it can be simplified to: 4-2a
How do you solve the equation a-16 equals a over 4 plus 2?
a-16 = a/4+2 Multiply all terms by 4: 4a-64 = a+8 4a-a = 8+64 3a = 72 a = 24
