Use the number line to represent. -4 1/2 + 3 1/4. what is the sum?

dlinn [17]

Answer:

$\displaystyle A+B=-\frac{5}{4}$

Step-by-step explanation:

<u>The Number Line</u>

Let's call

$\displaystyle A=-4\frac{1}{2}$

$\displaystyle B=+3\frac{1}{4}$

Both numbers are given as mixed fractions. Let's convert them to improper fractions:

$\displaystyle A=-4\frac{1}{2}=-(4+\frac{1}{2})=-\frac{8+1}{2}=-\frac{9}{2}$

$\displaystyle B=3\frac{1}{4}=3+\frac{1}{4}=\frac{12+1}{4}=\frac{13}{4}$

The decimal values are A = -9/2=-4.5, B=13/4 = 3.25

Now represent the points in the number line. See the image below

Finally, calculate their sum:

$\displaystyle A+B=-\frac{9}{2}+\frac{13}{4}$

$\displaystyle A+B=-\frac{18}{4}+\frac{13}{4}=\frac{-18+13}{4}$

$\boxed{\displaystyle A+B=-\frac{5}{4}}$

The difference between two numbers is 31. Four times the smaller is equal to eight more than the larger. What are the numbers?

hjlf

Answer:

13 and 44

Step-by-step explanation:

let x and y be the 2 numbers with y < x , then

x - y = 31 ( add y to both sides )

x = y + 31 ( subtract 31 from both sides )

x - 31 = y → (1)

4y = x + 8 → (2)

substitute y = x - 31 into (2)

4(x - 31) = x + 8

4x - 124 = x + 8 ( subtract x from both sides )

3x - 124 = 8 ( add 124 to both sides )

3x = 132 ( divide both sides by 3 )

x = 44

substitute x = 44 into (1)

44 - 31 = y , then

y = 13

the 2 numbers are 13 and 44
