Answer:

3x = 2x + 3.

Step-by-step explanation:

In the question it has been given that three times a number is three more than twice the number.

Let the number is x.

Then by the given statement 3x = 2x + 3

So equation formed can be used to find the value of x

3x - 2x = 3

x = 3

Therefore, the number is 3 and equation to be solved for x is 3x = 2x + 3.

Let the value of the number be represented as x. 

Then, write out an equation; 

3x=2x+3 <--- Solve for x now 
3x-2x=3 
x=3 

Therefore the number is 3. 

Hope I helped :)

Becky d james have a total of 4 2/8 feet of yarn. Becky has 1 5/8 feet of yarn. How many feet of yarn does james have?
ra1l [238]
Let
x----------------> <span>feet of yarn of Becky
y----------------> </span><span>feet of yarn of James

we know that
4 2/8------> 4 1/4--------> (4*4+1)/4-----> 17/4
1 5/8------> (1*8+5)/8-----> 13/5
x+y=4 2/8-------> x+y=17/4----> equation 1
x=1 5/8--------> x=13/5------> equation 2
substitute 2 in 1
[13/5]+y=17/4------> y=(17/4)-(13/5)----> y=[5*17-4*13]/20
y=(85-52)/20-----> y=33/20----> y=1.65-----> y=1 65/100----> y=1 13/20

the answer is
</span><span>james have 1 13/20 ft of yarn</span>

Licemer1 [7]

Answer:

x^{2}-10x+25

Step-by-step explanation:

We can rewrite the question as (x-5)*(x-5).

Using the FOIL Method (First, Outside, Inside, Last):

x^{2}-5x-5x+25

This simplifies to x^{2}-10x+25
