Answer:
value of x = 3
Step-by-step explanation:
here's the solution :-
=》f (x) = 4x + 5
and we know,
=》f (x) = 17
so, by equating both equations, we get :-
=》4x + 5 = 17
=》4x = 17 - 5
=》x = 12 ÷ 4
=》x = 3
In a parallelogram opposite angles are equivalent so B=D and A=C.
If B=D, 3n + 20 = 6n - 25; add 25 to both sides
3n + 45 = 6n; subtract 3n from both sides
45 = 3n; divide both sides by 3
15 = n; substitute 15 for n to find the value of angle B;
3(15) + 20 = B
45 + 20 = B
65° = B
Angles C and B are supplementary, which means that when added they equal 180°
so 180 = 65 + C
115 = C
Your answer is choice B

<u>Given</u>
- Had 200 pesos originally
- spends 'y' pesos on a notebook
- Bought 4 colored pens with the rest of the money
<u>Solving</u>
- Let money of the pen = x, money of notebook = y
- 4x + y = 200
- 4x + 80 = 200
- 4x = 120
- x = <u>30 pesos</u>
