Let's solve your equation step-by-step.
7(x+2)=6(x+5)
Step 1: Simplify both sides of the equation.
7(x+2)=6(x+5)
(7)(x)+(7)(2)=(6)(x)+(6)(5)(Distribute)
7x+14=6x+30
Step 2: Subtract 6x from both sides.
7x+14−6x=6x+30−6x
x+14=30
Step 3: Subtract 14 from both sides.
x+14−14=30−14
x=16
Answer:
x=16
Same as before, if we take 368 to be the 100%, how much is 20% off that?
so, the discount is that much, thus, the discounted price is then 368 - d.
Answer:
9.65×10¹⁴
Step-by-step explanation:
The 9 of 9.65 has been moved 14 places to the left to get to its position in 965,000,000,000,000. That is, its value has been multiplied by 10¹⁴.
_____
If you were to write 965,000,000,000,000 in expanded form, you would write it as ...
... 9×10¹⁴ +6×10¹³ +5×10¹² +0×10¹¹ +... +0×10⁰ = 9.65×10¹⁴
The first term of this sum is a clue as to how the number is written in scientific notation,
