Option B is your answer.
3/5x - 5 + 5/5x - 4 = - 1
8/5x - 9 = - 1
8/5x = - 1+ 9
8/5x = 8
Multiply both sides by 5/8 (the reciprocal of the coefficient) to isolate variable X.
(5/8)(8/5x) = 8(5/8)
x = 40/8
x = 5
Answer:
Step-by-step explanation:
a=30
b= 17
c= 18
we actually already found angles B and C for the last problem I think we said 30 and 32 so we would be able to guess that angle A is about 118° but.. let's do the math... and see
angle A = arcCos[ b^2 + c^2 - a^2 / 2*b* c ]
A = arcCos[ 289 +324 - 900 / 2*17*18]
A = arcCos[ -287 / 612 ]
A = arcCos[ -0.468954 ]
A = 117.9664 °
ohh and we're off by 0.0336 phooy :P soo far off... :P
rounding to nearest 10th
A = 118.0 ° ( ohh right on the money :P) yay, I feel better. :P
Answer:
9x
9 is the coefficient
Step-by-step explanation:
5x + 4x
These are like terms (they both have the same variable (x))
5x + 4x = 9x
The coefficient is 9, since it's the number in front of a variable.
Hope this helped!
Answer:
XW = 4 units
Step-by-step explanation:
Given tanf° = , then
tanf° = = = = ( cross- multiply )
2XW = 8 ( divide both sides by 2 )
XW = 4
Answer:
The answer is below
Step-by-step explanation:
The distance between two points is given by the formula:
1) (-4,6) and (3, -7)
2) (-6, -5) and (2,0)
3) (0, -8) and (3, 2)
4) (-1, 4) and (1, -1)
The midpoint (x, y) between two endpoints is given by:
The midpoints of the following segments are:
1) (15, 8) and (-1, -4)
2) M(-5,9) and N[-2.7)
3) P(-3,-7) and Q13.-5)
4) F(12.-6) and G(-8,5)
