The sum of these two angles is 180°, therefore,
138° + (x + 8)° = 180°.
Simplify the left side of the equation.
146° + x = 180°.
Subtract 146 from both sides.
x = 34°
Answer:
118 degrees; 30 degrees
Step-by-step explanation:
2x+14=1/2((6+14x)-58)
2x+14=1/2(-52+14x)
2x+14=-26+7x
40=5x
x=8
6+14(8)=6+112=118
2(8)+14=16+14=30
This question belongs to simple algebric equation, where we need to add or subtract fractions by finding a common denominator.
Given total hours = 120
Number of hours tutored for 1st week =2 1/3 hours = 7/3 hours
Number of hours in the 2nd week = 3/2 = 1.5 hours
Let the number of more hours she needs to teach be x
=
23 + 6x = 120
6x = 97
x = 16.167
Hence Kiara needs 16.167 more hours.
And this belongs to a part-whole problem, because the time she still needs to tutor is unknown.
Answer:
nepal = 11
Step-by-step explanation:
english = 4
Pakistan = 9
Australia =25
9×4 =36-25 =11
Y= 2x-4
4x+Y=2
4x+2x-4=2
6x-4=2
+4=+4
6x=6
6/6X = 6/6 X=1
Y=2X-4
2(1)-4
Y=-2
