Answer:

<h2>3. If a ≥ b, then a + c ≥ b + c </h2><h2>4. If c > d, then a– c < a – d</h2>

Step-by-step explanation:

The inequalities 3 and 4 are the right ones, because they are actually properties of inequalities.

The other choices aren't correct. For example, the first choice: a – b < a + b, it's not true, because you must apply the same change at each side of the inequality, otherwise you'll ruin the expression.

Choices 2 and 5 are also false.

Therefore, the right answers are 3 and 4.

32 divided by 4 = 8,

8^2 + 8^2 = 128

128: 11^2 = 121 close enough, 11 is your answer

We are finding hypotenuse but first we find the length of all sides of the two squares to find the two sides of the triangle then we find hypotenuse.

• Mother has 40 guavas to share among her daughters, Naomi got 3
scoray [572]

Answer:

Step-by-step explanation:

As given Total Guavas  = 40 ,

3 daughters,

Let   share of Sharon = x

then by given condition ,

Naomi share = x+3                  (3 more then Sharon

Also Kassie share = x+3+10 =x+13     (10 more then Naomi

Now

total shared = total

Naomi + Sharon + Kassie = 40

(x+3) +(x) +(x+13) =40

adding like terms with like we get ,

3x+16=40

3x=40-16

3x=24

x= 24/3

x= 8  

hence Sharon share = x =8

Naomi share = x+3 =8+3 =11

Kassie share = x+13 = 8+13 = 21

Plz Brain-list it     or subscribe to my channel " ZK SOFT&GAMING "  Thanks....
