Answer:
$420
Step-by-step explanation:
(100 - 40)x = 60x
60x - 20 = 40x
0.4x = $168
x = $168/0.4 = $420
Answer:
3/2-u
Step-by-step explanation:
You need to break the question down by seeing that is it asking for u less than something so that means subtraction. You then see the quotient of 2 and 3 so then you put 3 over 2 to divide and then put your subtract 2 onto it

X = 8.5 because 8.5 x 2 = 17 and 17 + 1 = 18
Two angles are supplementary if their sum is 180 degrees.
Here we are given:
Angle GHI measures (28x + 40)° and angle JHI measures (7x)°.
Sum of angle GHI and JHI is 180.



dividing both sides by 35,
x=4
Now let us find angle JHI
angle JHI = 7x = 7*4 =28
Answer : Angle JHI is 28 degrees.
