first place the c's and f's next to each other.
8c-c-3f-3f
now
8c-c = 7c
and
-3f -3f = -6f
your answer is 7c-6f
Remember that you cannot add of subtract from different letters you can only add of subtract like terms
-8c + 1 = -3 => -8c = -3 + 1 => -8c = -2 => c = -2/(-8) => c = 1/4 = 0.25
5f-2
If 8c = 60, then c = 60/8 = 7.5.
8c + 24 + 23 = 71subtract 47 from each side, 8c = 24divide each side by 8, c = 3
2. c2 + c2 + 8 = 8c 2c2 - 8c + 8 = 0 c2 - 4c + 4 = 0 (c - 2)(c - 2) = 0 (c - 2)2 = 0 c - 2 = 0 c = 2
-8c + 1 = -3 => -8c = -3 + 1 => -8c = -2 => c = -2/(-8) => c = 1/4 = 0.25
5f-2
If 8c = 60, then c = 60/8 = 7.5.
-8c+1 = -3 -8c = -3-1 -8c = -4 Divide both sides by -8 in order to find the value of c remembering that a minus number divided into minus number is equal to a plus number: c = 1/2
8c + 24 + 23 = 71subtract 47 from each side, 8c = 24divide each side by 8, c = 3
2. c2 + c2 + 8 = 8c 2c2 - 8c + 8 = 0 c2 - 4c + 4 = 0 (c - 2)(c - 2) = 0 (c - 2)2 = 0 c - 2 = 0 c = 2
It is: 6-11+5-8c+9c = c
The expression (8c - 64) cannot be simplified to a single numerical answer without knowing the value of (c). If you want to solve for (c) when the expression equals zero, you would set it up as (8c - 64 = 0), which simplifies to (c = 8). If you provide a specific value for (c), I can help calculate the result.
(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)].
divide 120 by 8 and that is C
Oh, dude, that's like super easy. So, 7c plus c is basically just adding up the number of c's, which gives you 8c. It's like math, but with letters instead of numbers. So yeah, 7c plus c equals 8c. Math made fun, right?
-15 = 8c - 15Add 15 to each side:0 = 8cDivide each side by 8:c = 0
