Answer:

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3 /4 n+ 1 /4 = 1 /2

Step 2: Subtract 1/4 from both sides.

3 /4 n+ 1 /4 − 1 /4 = 1 /2 − 1 /4

3 /4 n= 1 /4

Step 3: Multiply both sides by 4/3.

( 4 /3 )*( 3 /4 n)=( 4 /3 )*( 1 /4 )

n= 1 /3

Write a problem situation for this inequality 72-12a<24

Morgarella [4.7K]

Answer:

Subtracted 12 times a number from 72 is less than 24.

Step by step solution

Given inequality is $72-12a$

We need to write in word.

12a means 12 times a number “a”

72-12a means subtract 12a from 72.

72-12a<24 means result is less than 24.

Inequality shows “Subtracted 12 times a number from 72 is less than 24”

If we solve for number “a”

-12a<24-72

-12a<-24

a>2

All the number greater than 2 satisfy the given inequality.

Do 18/24 and 10/15 have the same value? Explain your answer in complete sentences.

LenaWriter [7]

Answer:

Step-by-step explanation:

We can either cross multiply or turn into decimal form to see if they have the same value.

I will be showing both.

Cross Multiply: Decimal Form:

$\frac{18}{24} \;[\;\;] \frac{10}{15}$ $\mathrm{To\;turn\;fraction\;into\;decimal\;just}$

$18\times15=270$ $\mathrm{Divide\;numerator \;by \;denominator\;}$

$24\times10=240$ $\mathrm{18\div24=0.75}$

$\frac{18}{24} \;[ > ] \frac{10}{15}$ $\mathrm{10\div15=0.66666666666}$

$\mathrm{As\;a\;result\;we\;can}$ $0.75 > 0.66666666666$

$\mathrm{conclude\;that\;\frac{18}{24} \;is\;greater\;than\;\frac{10}{15}}$ $\frac{18}{24} \;[ > ] \frac{10}{15}$

We can conclude that 18/24 and 10/15 are not the same.
