Igoryamba

A = 1
b = -1

a + b =
1 + (-1) =
1 - 1 =
0....so a + b = 0

Last time, one out of every 4 students in our class was absent. This time, after Jen came back, only one out of every 5 students

VMariaS [17]

Answer: There are 20 students and 4 students are not here today.

Step-by-step explanation:

If the number of students = 4

Let the number of students be 'x'.

Fraction of students absent = $\dfrac{x}{4}$

If the number of students = 5

Fraction of students absent = $\dfrac{x}{5}$

And Jen came back,

So, the fraction of student absent is also written as

$\dfrac{x}{4}-1$

According to question, it becomes,

$\dfrac{x}{5}=\dfrac{x}{4}-1\\\\\dfrac{x}{5}=\dfrac{x-4}{4}\\\\4x=5(x-4)\\\\4x=5x-20\\\\4x-5x=-20\\\\-x=-20\\\\x=20$

Hence, there are 20 students in our school.

And number of students are not here today is $\dfrac{20}{5}=4$

1: A woman buys a car making a $3,000 down payment and then agrees to make 48 monthly payments of $360. What is the total cost o

katrin [286]

Answer:

1. $20280

2. 117 h

Step-by-step explanation:

to know the value of the car we have to add all the monthly payments with the $ 3000 that she paid at the beginning

x = car value

x = $3000 + 48 * $360

x = $3000 + $17280

x = $20280

The total cost of the car is $20280

To know how many hours I work in total we have to add the hours I work in each day 5 times with the 57 hours I work the following week

x = hours that work in all

x = 5 * 12 + 57

x = 60 + 57

x = 117

work for 117 hours in all
