marishachu [46]
<span>m = j + 16
m + 5 = 3j
---
put the system of linear equations into standard form
---
m - j = 16
m - 3j = -5
---
x - y = 16
x - 3y = -5

so now that you have your equations formed, just solve. 

x - y = 16 , which means that x = y + 16 
substitute for x in the second equation :

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.
