<< Add

to the left and right of the equation, multiple and make ''opposite multiplation'' to find x.
A)


25x.(-32)= (-16).5
-800x= -80
**to leave x alone and positive, you must divide to -800.


= INCORRECT
B)





C)



10x=1

D)


40x= 4
x=

= 1/10
I think there is a problem with the options :D
Answer:
b-4.2<-7.5
Step-by-step explanation:
b-4.2<-7.5
this is because the number given as "b" minus 4.2 (as shown on the left) is less than (<) -7.5, so this inequality makes sense.
Answer:
x is equal to 6
Step-by-step explanation:
in a circle the perpendicular from centre to any chord bisects the chord into 2 equal parts.
Graphing an inequality is when you shade in the graph based on whether your point that you chose(usually (0, 0)) is true or false when put back in the original equation.
Graphing an equation of a line is just a line on the graph.
For a solid line: the inequality should be greater then or equal to or less then or equal to.
For a dashed line: the inequality should just be greater then or less than.
Hope this helps for your inequality equations :)
Answer: 32 and 42
Step-by-step explanation:
5j +12
j= 4
j = 6
5(4) + 12
5 times 4 = 20
20 + 12 = 32
5(6) + 12
5 times 6 = 30
30 + 12 = 42
