Two fewer than a number doubled is the same as the number decreased by 38. if n is "the number," which equation could be used to
Alona [7]
   
\displaystyle \\ 
\text{We use the following equation:} \\  \\ 
 \frac{n}{2} = n - 38 \\  \\ 
We solve for n: \\  \\ 
 \frac{n}{2} = n - 38 ~~\Big| \times 2 \\  \\  
n = 2 \times  n - 2 \times 38 \\  \\ 
n = 2n - 76 \\  \\ 
2n - n = 76 \\  \\ 
\boxed{n = 76} \\  \\ 
\text{Verification: } \\  \\ 
\frac{n}{2} = n - 38 \\  \\ 
\frac{76}{2} = 76 - 38 \\  \\ 
\boxed{38 = 38  ~~~ Correct }

Which expressions are equivalent when m = 1 and m = 4?
s344n2d4d5 [400]

Answer:

expression 2

Step-by-step explanation:

<h2><u>Which expressions are equivalent when m = 1 and m = 4?</u></h2>

<h3><u>first expression:</u></h3>

5m -3 and 2m + 5 + m

when m = 1

5(1) - 3 = 2  and 2(1) + 5 + 1 = 8

and m = 4

5(4) -3 =23 and  2(4) + 5 + 4 = 17

<u>expression 1 IS</u><u> NOT EQUIVALENT</u><u> </u>

<h3><u>second expression  :</u></h3>

3 m + 4 and m + 4 + 2 m

when m = 1

3 (1) + 4 = 7 and 1 + 4 +2 (1) = 7

and m = 4

3 (4) + 4 = 16 and 4 + 4 +2 (4) = 16

expression 2 <u>IS  EQUIVALENT </u>

<h3><u>third expression :</u></h3>

2 m + 7 and 3 m - 3 + m

when m = 1

2(1) + 7 = 9 and 3(1) -3 + 1 = 1

and m = 4

2(4) + 7 = 15  and 3(4) -3 + 4 = 13

expression 3 IS <u>NOT EQUIVALENT</u>

<h3><u>fourth expression :</u></h3>

5 m + 3 and 4 m + 2 + 2 m

when m = 1

5(1)+ 3 = 8  and 4(1) + 2 +2(1) = 8

and m = 4

5(4)+ 3 = 23  and 4(4) + 2 +2(4) = 26

expression 4 is <u>NOT EQUIVALENT </u>

the expression that is <u><em>EXPRESSION 2 </em></u>
