Choose Yes or No to tell whether the Addition Property of Inequality can be used to solve each statement. w – 4 > –10 12 ≥ 20
Alex

Answer:

No

Step-by-step explanation:

The inequality will not be the same if the same amount is added both sides.

The addition property states that if the same quantity is added to both sides, then the inequality still remains true. Take for example:

let x, y, and z be real numbers. It follows that:

if x ≥ y, then x + z ≥ y + z

This holds true for whatever value of z

If x ≤ y, then x + z ≤ y + z

The inequality remains true.

Can someone help with this please?
Norma-Jean [14]

Answer:

n=11

Step-by-step explanation:

By inspection,we see that an output is obtained by subtracting 3 from an input and the next consecutive output will follow a pattern of a difference of odd numbers that is 9+5=14

so n=14 and 14-3=11

David&dan share a lottery win of £9900 in the ratio 3:2 David then shares his part between himself,his wife and their son ho
mixer [17]

Answer:

Step-by-step explanation:

The question is incomplete. The complete question is:

David & Dan share a lottery win of £9900 in the ratio 3 : 2. David then shares his part between himself, his wife & their son in the ratio 4 : 4 : 2. How much more does his wife get over their son?

Solution:

David & Dan share a lottery win of £9900 in the ratio 3 : 2. The total ratio is 3 + 2 = 5

The amount that David got would be

3/5 × 9900 = £5940

Therefore, £5940 was shared in the ratio of 4 : 4 : 2. The total ratio is 4 + 4 + 2 = 10

The amount that his wife gets is

4/10 × 5940 = £2376

The amount that his son gets is

2/10 × 5940 = £1188

The amount that his wife gets over their son is

2376 - 1188 = £1188
