If a number is not divisible by 11 ​, can it be divisible by 22​?

Mathematics

RoseWind [281]3 years ago
4 0

Answer:

Well the divisibility rule for 22 is that the number must be divisible by 2 and 11. In order for something to be divisible by 2 it needs to end in 0, 2, 4, 6, or 8. For the number 11 the, if the difference between the odd numbered digits and the sum of the even numbered digits is a multiple of 11 then it is divisible by 11.

So I would say no for both of them since 22 is divisible by 11.

Please let me know if I'm wrong.

DOES ANYONE KNOW HOW TO DO THIS???
Anna11 [10]

Answer:

Cost of a pound of chocolate chips: $3.5

Cost of a pound of walnuts: $1.25

Step-by-step explanation:

x - cost of a pound of chocolate chips

y - cost of a pound of walnuts

We create two equations based on the information we have:

3x+2y=13

8x+4y=33

The whole point of these problems os to get rid of x or y. In this question, we can do this by multiplying both sides of the first equation by 2, and then subtracting it from the second equation:

8x+4y=33

6x+4y=26

2x=7

x=3.5

Then we change x for 3.5 in the first equation:

3×3.5+2y=13

10.5+2y=13

2y=2.5

y=1.25

Hope this helps!

When determining if you have a perfect square trinomial, what must the first and third term be?
cricket20 [7]

The expansion of a perfect square is

(a+b)^2 = a^2+2ab+b^2

In words, the square of a sum of two terms is the sum of the squares of the two terms (a^2 and b^2), plus twice the product of the two terms (2ab)

So, when determining if you have a perfect square trinomial, you should have two perfect squares. Note that they don't have to be the first and third term, since you can rearrange terms as you prefer.

Pls help me with this problem!!!!
kolbaska11 [484]

Answer: 55°

Step-by-step explanation:

∠YAZ + ∠YAX = 180° because they are linear pairs

∠YAZ + ∠YAX = 180°

∠YAZ + 125 = 180

Subtract both sides by 125

∠YAZ = 55°

Hope that helped!
