If you would like to solve (- 0.5) / (- 0.5) and - 50 / (- 0.5), you can do this using the following few steps:
(- 0.5) / (- 0.5) = 0.5 / 0.5 = 1
- 50 / (- 0.5<span>) = 50 / 0.5 = 50 / (5/10) = 50 / (1/2) = 50 * 2/1 = 100
</span>
The correct results would be: (- 0.5) / (- 0.5) = 1 and - 50 / (- 0.5<span>) = 100.</span>
So,
53,879 rounded to the nearest hundred:
If the number in the tens place is greater than or equal to 5, then round up. If not, round down.
7 is greater than or equal to 5, so round up.
53,879 --> 53,900
Answer:
x - 5
Step-by-step explanation:
Answer:
Ca^(2+) or the charge is 2 plus or just 2
Step-by-step explanation:
Charge on the calcium ion = 20*(+1) + 18*(-1) = 20 - 18 = 2
The charge on the calcium ion is +2
Step-by-step explanation:
The equation that represents the perimeter of the rectangle is given as;
2x + 2(x + 2) = 24 where x represents the width.
We solve for x;
2x + 2x + 4 = 24
4x + 4 = 24
4x = 24 - 4
4x = 20
x = 20/4
x = 5
We were informed that the length of the rectangle is 2 inches more than its width. This implies that the length is x+2 = 5+2 = 7.
The value of x from the set {1, 3, 5, 7} that holds true for the equation is 5. So, the width of the rectangle is 5 inches and its length is 7 inches.
