Solve for x.
X+2 1/4=4 3/4
A.)1 3/4
B.)2 1/4
C.) 2 1/2
D.) 2 3/4

C.) 2 1/2

Step-by-step explanation:

X + 2 1/4 = 4 3/4

Change the fractions to improper fractions .

We have

X + 9/4 = 19/4

Subtract 9/4 from both sides

X + 9/4 - 9/4 = 19/4 - 9/4

X = 19/4 - 9/4

Look for the LCM of the denominators.

The LCM is 4

Divide the LCM by the denominators and multiply the results by the numerators, the lcm becomes the denominator of the results.

That’s

X = 19 - 9 /4

= 10/4

Divide both numerator and denominator by 2

= 5/2

= 2 1/2

C.) 2 1/2

Step-by-step explanation:

X+2 1/4=4 3/4

Subtract 2 1/4 from each side

X+2 1/4  - 2 1/4=4 3/4 - 2 1/4

x = 2 2/4

This simplifies to

x = 2 1/2

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

your exact question is kind of difficult to understand, so maybe an example will explain what you're supposed to do? i'll work through the first problem on the worksheet.

suppose you have a tray of 652 brownies, and you have 5 friends that you want to feed without picking favorites. how many brownies can you dole out to each of your friends in equal amounts? how many will be left over for you to eat?

what you're doing here is finding a way to arrange the number 652 as the sum of integer multiple of 5 and some remainder:

here ("q" for quotient) is the number of brownies each of your friends get, and is the remainder. that's the basic idea behind division.

we break up the number 652 into parts so that the leading digit stands on its own:

652 = 600 + 52

first we check if it's possible to hand out exactly 100 brownies to each friend. with 5 friends, this means we want to know if we can take out 500 brownies from the tray. we can do this 1 time because we have 600 brownies to take from, and when we do that we're left with 100 + 52 brownies to divvy up. so we know that

652 = 1*500 + 152

next we want to know if it's possible to hand out exactly 10 brownies per friend. if we can, we have to remove 50 brownies from the tray each time until we can't. we have 152 brownies left, and we know that 3(50) = 150, so

152 = 3*50 + 2

now we have 2 brownies left in the tray. is it possible to hand 1 out to each of your 5 friends? no, you'd need a minimum of 5 brownies to do that. so the last 2 are yours.

putting everything together, we found that

652 = 1*500 + 3*50 + 2

and we can rearrange this to write

652 = 5*100 + 5*30 + 2

652 = 5(100 + 30) + 2

652 = 5*130 + 2

so and .
