Answer: the number is - 18
Step-by-step explanation:
Let the number be represented by x.
If the sum of a number and seven is doubled, the result is four less than the number. The expression would be
2(x + 7) = x - 4
We would open the bracket on the left hand side of the equation by multiplying each term inside the bracket by 2. It becomes
2x + 14 = x - 4
Subtracting 14 and x from the left hand side and the right hand side of the equation, it becomes
2x + 14 - 14 - x =x - x - 4 - 14
x = - 18
The correct answer for that question is 280
Answer:
First picture: -4,913
Second picture: 20.25
Step-by-step explanation:
-17^5/-17^2 = -17^3
-17 × -17 × -17 = -4913
4.5^5/4.5^3 = 4.5^2
4.5 × 4.5 = 20.25
Do you see how I had the same whole number on the top and bottom? (17 was on top and 17 was on bottom)
The exponents were those tiny numbers you saw.
Whenever you are dividing by the same whole number (-17/-17), you can subtract exponents.
When you multiply the same whole number, you can add the exponents.
Hope this helps! Best of luck :)
