co= same planar = plane
coplanar means "same plane"
Answer: D
First you multiply 3 times x and 3 times 2
4(3(x + 2) -1) =50
and get
4( 3x +6 -1) =50
then you add 6 plus -1
4 ( 3x +5) = 50
then multiply 4 times 3x and 4 times 5
12x +20 = 50 and subtract 20 from both sides
-20 -20
and you will get
12x = 30
divided both sides by 12
12x/12 = 30/12
then you find the ones that are the same amount in decimals but are smaller
and that's your answer: x= 5/2
hope you get it!!!
Answer:
The most absolute error is 12
Step-by-step explanation:
The formula for absolute error is given by the following relation;
Absolute error, Δx = Value measured, x₀ - Exact (actual) value, x
Δx = x₀ - x
Since the actual count is between 77 and 89, the maximum absolute error will be where the actual value = 77 and the measured value = 89 and vice versa, giving an absolute error of 89 -77 = 12.
The most absolute error = 12.
The GCF of 72 is 60 is 12.
Answer:
BZ = 64/23 = 2 18/23
Step-by-step explanation:
The angle bisectors divide the triangle into proportional parts, so we have ...
CB/CY = AB/AY
CB = CY(AB/AY) = 4(8/6) = 16/3 . . . . multiply by CY and evaluate
and ...
BZ/CB = AZ/AC
BZ = AZ(CB/AC) . . . . multiply by CB
But we have ...
AZ = 8 -BZ, so this becomes ...
BZ = (8 -BZ)(16/3)/(10)
BZ(1 +8/15) = 64/15 . . . . add the BZ term on the right to both sides
BZ = (64/15)(15/23) = 64/23 . . . . divide by the coefficient of BZ
BZ = 64/23 = 2 18/23
