Sum of two consecutive even intergars divided by 4 is189.5

So! What we have here is the following equation!

My suggestion to you is to "solve" for the sum of your two numbers (a+b). This will help a lot!

To solve for our sum (a+b) multiply both sides by 4. You get the following equation after you multiply 189.5 by 4 and cancel out the 4/4 on the left:

a+b = 758

Now our job is pretty simple from here. Simple divide 758 by 2.

= 379

If you remember from basic math division is the same as saying what "x" amount of numbers added together equal my number. Where "x" is the number you divide by. So what we have is two numbers which add to equal our number. We need the number to be two consecutive even numbers. Consecutive meaning back to back.

We currently are looking at this equation:
379 + 379 = 758

While it is correct, we need to change it a bit. Think about how we can make the numbers consecutive even numbers without changing what they add up to. Add and Subtract 1 from the problem.

379 + 1 + 379 - 1 = 758

378 + 380 = 758

So, our two numbers are 378 and 380. If you want you can check it with our original equation.

= 189.5

Turns out that the statement is true, so these two numbers work!

378, and 380

The difference between a number and 21 1/2 is no more than 14 1/4

ni this problem i consider that the notation 21 1/2 is equivalent to 21 + 1/2 = 21.5

our phrase is:

"The difference between a number and 21 1/2 is no more than 14 1/4"

we can break it into two parts to make it easier.

"The difference between a number and 21 1/2"

this is a subtraction, here you are subtracting 21 1/2 to a number, let's call this number x, then we can write this as:

x - 21 + 1/2

or x - 21.5

the second part says: "is no more than 14 1/4"

then the thing that we got before, is less or equal than 14 1/4 (or 14.25), this is

x - 21.5 ≤ 14.25

now you can add the same number in both sides of the inequality and it remains the same, then you can add 21.5 to both sides and:

x - 21.5 + 21.5 ≤ 14.25 + 21.5

x ≤ 35.75

Which of the four triangles was formed by a translation of triangle XYZ? A B C D

Options A & B

Step-by-step explanation:

Given is a triangle XYZ in the I quadrant.  There are four more triangles A, B,C and D given.

We have to find that which one is the translation of XYZ

We know that by translation we must get a congruent triangle as XYZ.

By simply seeing we can say that C and D are not congruent with XYZ.

So these two are eliminated

Remaining are A and B.

Both A and B are right

This is because XYZ is transformed into B by shifting 7 units horizontal to the left.

A is the reflection of B about x=-5.5

Thus both A and B are right
