Mathematics
1 answer:
Kay [80]3 years ago

8. There is no solution. The absolute value of a number is always positive.
9. There are two solutions. Since the absolute value of a number is always positive, a solution can either be 4 or -4.
10. There is no solution because of the same reason for number 8.
11. There is one solution. There really is not -0.
12.  There are two solutions. Since the absolute value is always positive, the solution can be either 15 or -15.

Como resolver y=1-2.5
oksian1 [2.3K]

I don't really speak Spanish but I'll guess that says

 How do I solve  y = 1 - 2.5

Unless I'm missing something, there's not even any algebra here.  

The way we subtract a bigger number from a smaller number is first we subtract the smaller number from the bigger number the regular way, then we prepend a minus sign.


y = 1 - 2.5 = -(2.5 - 1) = -1.5

a farmer sells his corn for $230 a metric ton with a small surcharge of $25. his neighbor sells her corn for $230 a metric ton a
anyanavicka [17]

Step-by-step explanation:

Step one:

The farmer sells his corn for $230 a metric ton

small surcharge = $25.

let the amount per metric ton be x

and let the total cost per x metric ton be y

the total cost function is

y=230x+25--------------1

The neighbor sells her corn for $230 a metric ton

he gives $15 rebate------<em>A rebate is a partial refund of the cost of an item</em>

let the amount per metric ton be x

and let the total cost per x metric ton be y

the total cost function is

y=230x-15----------------2

Step two:

Equating the two equation above

230x+25=230x-15

230x-230x=25+15

0=40

The result shows that based on the cost function of both farmer, there will never be an amount of corn that would make them have the same cost

klio [65]

Answer: There are 8 students at Hamilton Middle School with red hair.

Step-by-step explanation:

Given: The proportion of the students at Hamilton Middle School have red hair = 2% = 0.02

Total students in  Hamilton Middle School = 400

Then , the number of students have red hair = (proportion of the students have red hair ) x (Total students )

= (0.02) x (400)

= 8

Hence, there are 8 students at Hamilton Middle School with red hair.
