Which ordered pair is a solution of the equation?
julia-pushkina [17]
Lets solve for both possibilities.

A. (2,4)

<span>-3x+5y=2x+3y
-3(2)+5(4)=2(2)+3(4)
-6+20=4+12
14</span>≠16
Incorrect

B. (3,3)

<span>-3x+5y=2x+3y
-3(3)+5(3)=2(3)+3(3)
-9+15=6+9
6</span>≠15
Incorrect

Neither ordered pairs work for the equation.

Reduce the fraction to lowest terms. y+5/2y+10<br><br>A:1/4<br>B:1/2<br>C:2/5
Oduvanchick [21]
The given fraction is:

\frac{y+5}{2y+10}

We cannot take anything common from the numerator but from the denominator we can take out 2 as common because 2 is a factor of both the terms i.e. 2y and 10. 

2y + 10 can be written as 2y +2(5) which can further be written as 2(y+5)

So, our fraction now becomes:

\frac{y+5}{2(y+5)}

y+5 occurs in both the numerator and denominator and thus be cancelled out leaving behind:

\frac{1}{2}

Therefore, the given fraction in lowest term is equal to 1/2. So option B is the correct answer

xxTIMURxx [149]
Answer: 11/4 x 7 = 11/2 ; 3/35 x 7 = 3/5 ; 5/7 x 7 = 5. So, the last three you listed work with 7 in the blank.

Suppose that the division N/5 leaves a remainder of 4, and the division N/2 leaves a remainder of 1, what is the ones digit on N
Tju [1.3M]

Since <em>N</em>/2 leaves a remainder, <em>N</em> must be odd and ends with 1, 3, 5, 7, or 9.

<em>N</em>/5 also leaves a remainder, so <em>N</em> is not divisible by 5, so it does not end in 5.

The only correct choice is then 9, since

1 = 0•5 + 1 and 1 = 0•2 + 1

3 = 0•5 + 3 and 3 = 1•2 + 1

7 = 1•5 + 2 and 7 = 3•2 + 1

9 = 1•5 + <u>4</u> and 9 = 4•2 + <u>1</u>

<u />

Alternatively, the given information is equivalent to saying

N\equiv 4\pmod5\\\\N\equiv1\pmod2

Then you can use the Chinese remainder theorem to find <em>N</em>.
