Answer:
JK=7
Step-by-step explanation:
From the line segment, since J is on it ,it means the line segment is
represented as I J K
from this illustration, we can say that the longest part of the line segment is from I to K
this means that, IJ +JK =IK
making JK the subject,
JK= IK - IJ
but from the question, JK=2x-1 , IK=3x+2 and IJ=3x-5
substituting them in the expression,
2x-1 =3x+2 -(3x-5)
solving for x
2x-1 =3x+2-3x+5
2x-1 =0+7
2x-1 =7
2x=1+7
2x=8
dividing through by 2
2x/2 =8/2
x=4
but the question says we should find the numerical value for JK
but from the line segment,
JK=2x-1
but now we know the value of x to be 2
so substituting it in the formula
JK= 2(4)-1
JK=8-1
JK=7
therefore, the numerical value for JK is 7
2=5-3 so the answer is (2, 5)
Answer:
square root of 21 is 4.6
square root of 62 is 7.9
Step-by-step explanation:
square root of 21 is 4.6
square root of 62 is 7.9
The answer is 56.8
explaination:14.2 x4
56.8
he needs five units he already have 1 unit
so5 minus 4=one
so....
14.2x4=56.8//
