Three times a number increased by 8 is no more than the number decreased by 4. Find the number ( please write and solve inequali
Alexandra [31]

Three times a number =   3x

Increased by 8 =               + 8

So far we have:  3x + 8

no more than =    <=  

the number decreased by 4 =  x -4

Put it all together and we have:

3x + 8 <= x - 4

Solve for x

3x + 8 <= x - 4

3x - x <= -4 - 8

2x <= -12

2x / 2 <= -12 / 2

x <= -6

-6 is the number / answer.

Please help me with these 5 problems!!!
zalisa [80]

1. let the score on 1st test be = x

Given average is = 92

2nd tests scores are = 97 (assume this as y)

3rd test score = 89 (assume this as z)

Average = \frac{x+y+z}{3}

92=\frac{x+97+89}{3}

276=186+x

x=90

Hence, 1st day score was 90.

2. Let the original recipe made x cookies

As given she doubled her recipe so 2x cookies

Her brothers ate 8 cookies, this gives 2x-8 cookies left

She gave 2 dozen or 24 cookies to the neighbor and left with 12 cookies, it becomes 2x-8-24=12

This gives 2x=44

or x=22

Hence 1 recipe makes 22 cookies.

3. As given in the table,

Time used in total by boys = 255 minutes

Time used by girls in total = 213 minutes

Time used for school work by boys = 33 minutes

Time used by boys other than schoolwork = 255-33 = 222 minutes

Time used for school work by girls = 72 minutes

Time used by girls other than schoolwork = 213-72 = 141 minutes

How many more minutes per week do boys spend using the internet for purposes other than schoolwork then girls = 222-141 = 81 minutes

Hence, boys use 81 more minutes than girls for work other than schoolwork.

4. Total amount by two films = $775 million

Let x be the receipts of the second highest box office film.

Let x + 97 be the receipts of the highest one.

Equation becomes x+x+97=775

2x+97=775

2x=678

x=339

Hence highest receipt movie brought in 339+97=436

The film with highest receipts bought in $436 million.

5. Vice President elected in the year = 1944

Died in the year = 1972

Total time in between  = 1972-1944=28 years

Age at the time of death = 88

So, he was  elected 28 years back and that time his age was = 88-28=60

He was elected at the age of 60 years.

Can someone help me. I’ve tried doing this on paper. I don’t know what I’m doing wrong
IrinaK [193]
ANSWER: x=12
EXPLANATION:
9+x/6=11
(54+x)/6=11 (finding common denominator)
x/6=11-54/6 (rearranging terms)
x/6=(66-54)/6 (finding common denominator so 6 gets cancelled from both the sides)
x=12
