Answer:
just guess c its mostly right
Step-by-step explanation:
14. 5x-2x=12
3x=12
X=4
15. 8b+12=6b-30
2b=42
B=21
Answer: (x–2) and (10x+7)
Step-by-step explanation:
10x^2 – 13x – 14=
10x^2 – 20x + 7x – 14=
10x(x–2) + 7(x–2)=(x–2)(10x+7) ==> 3rd option
Answer:
the answer to this question is 785
I'll assume you're asking for the initial price
Let's use x to represent it
The initial price plus 40 percent of that is $294
Let's write that out mathematically
x + (40/100)x = 294
x + 0.4x = 294
1.4x = 294
x = 210
The initial price is $210
