Answer:
The regular price was $53.85
Step-by-step explanation:
78% = $42
42 ÷ 78 x 100 = 100% = $53.85 (when rounded to 2 d.p)
I'm assuming what you mean is what can you divide 3456 by to get a natural number.
First of all every number is divisible by 1.
Every even number is divisible by 2, so since 3456 is an even number, it can be divided by 2. That would equal 1728.
2456 can also be divided by 3, to get 1782.
You can also divide it by 4, to get 865.
Divided by 6, it's 576.
Divided by 8, it's 432.
And lastly, 3456 divided by 9 is 384.
So, there isn't just one single-digit number you can divide 3456 by to get a natural number. You can divide it by 1,2,3,4,6,8, and 9.
Hope that helps!
You need to d to one side of the equation by itself and them use PEMDAS to solve your answer
Answer:
x = -5, y = -6, z = -3
