Suppose the temperature outside is dropping 3 degrees each hour. How much will the temperature change in 8 hours?
Answer:
24 degrees
Step-by-step explanation:
doesn't matter how you set up the fractions, just make sure the degrees are both on top or both on bottom

1. Number one is correct, when we simplify the both of them, they are correct pr the same value. 1.5 = 1.5
2. Number two is also correct 38=38
3. And number three is also correct 2.4 = 2.4
All in all, all of them are correct, good job :)

Which could be used to evaluate the expression -6(4 2/3)?
Answer:
The answer is A
-6[4 2/3]
= -6[4+2/3] because 4 2/3 is 4 and 2/3rds
so a(b+c) = a(b) + a(c)
so -6(4) + -6(2/3)
4x - 9 = 2x + 7.
I need correct explanation with please.
Answer:
8
Step-by-step explanation:
4x - 9 = 2x + 7
4x - 2x = 7 + 9
2x = 16
x = 16 / 2
x = 8
Here, we are given with an equation in which we are given with some constants and two same variables x. We are said that the LHS and RHS are equal to each other. We are asked to find the value of the variable x. To find the value of x, we use an other concept which helps us to find the value of x and also to verify our answer. This concept is called as the transposition method. While using this method, the sign of the appropriate number or variable changes. We use this method to shift the numbers and variables on two separate sides. We can also verify our answer at the end of our answer by verification method. So, let's solve!!
[tex]\:[/tex]
➤ Solution :-[tex]{\sf \leadsto 4x - 9 = 2x + 7}[/tex]
Shift the variable value to LHS and the constant value to RHS, changing it's sign.
[tex]{\sf \leadsto 4x - 2x = 7 + 9}[/tex]
Subtract the values on LHS and add the values on RHS.
[tex]{\sf \leadsto 2x = 16}[/tex]
Shift the number 2 from LHS to RHS.
[tex]{\sf \leadsto x = \dfrac{16}{2}}[/tex]
Simplify the fraction to find the value of x.
[tex]{\sf \leadsto x = 8}[/tex]
[tex]\:[/tex]
[tex]{\red{\underline{\boxed{\bf So, \: the \: value \: of \: x \: is \: 8.}}}}[/tex]
━━━━━━━━━━━━━━━━━━━━━━━
Verification :-[tex]{\sf \leadsto 4x - 9 = 2x + 7}[/tex]
Substitute the value of x.
[tex]{\sf \leadsto 4(8) - 9 = 2(8) + 7}[/tex]
Multiply the numbers in the bracket.
[tex]{\sf \leadsto 32 - 9 = 16 + 7}[/tex]
Subtract the values on LHS and add the values on RHS.
[tex]{\sf \leadsto 23 = 23}[/tex]
So,
[tex]{\sf \leadsto LHS = RHS}[/tex]

In evaluating the limits of rational functions, the numerator and the denominator was found out to be both equal to zero, what does it mean?
Answer:
If only numerator found as zero the answer would be zero. If only denominator found as zero the answer is undefined. In your situation both are zero. But, when denominator becomes zero the answer always be undefined. Therefore, your answer is undefined when both numerator and denominator are zeros.

Find two numbers whose product is -6 and whose sum is 1.
Answer:
-2, 3
Step-by-step explanation:
yeah that's it I don't have any explanation or formula
let the numbers be x and y
xy = -6
x + y = 1
from x + y = 1
y = 1 - x
x(1 - x) = -6
x - x² + 6 = 0
-x² + x + 6 = 0
on solving,
x = -2 or x = 3
y = 1 - (-2) = 3
y = 1 - 3 = -2
x1 = -2, y1 = 3.
x2 = 3, y2 = -2.
5x – 10 > 20 or 5x – 10 ≤ –15

there are 16 boysin an english class of 28 students. the ratio of boys to the total numbers of students in this class is typical of the whole school. there are 476 students in the school. about how many are boys.
Answer: 272 boys
Step-by-step explanation:
16:28 can be simplified
4:7
Divide the total # of students by 7 then multiply it by 4

1.Write an expression to model its height after x minutes
2. Find the expression for 2,5,8,10,15 minutes
Answer:
2,520 - 140x
2,520 - 140(2) = 2,240
2,520 - 140(5) = 820
(etc etc)
Step-by-step explanation:
This equation can handle any numbers.
Answer:
1. 2520 - 140x
Add up the minutes

Mrs. Castro left her parents' house in the province and drove home.
After driving for 3 hours, she was 90 km from home, and after
5 hours, she was 25 km from home. Assuming that the distance from
home and the number of hours driving form a linear relationship,
how long did it take Mrs, Castro to drive from her parents' house
to her home? How far was Mrs, Castro from home after driving
6 hours? How long had Mrs. Castro been driving when she was
50 km from home?
Answer:
Distance problems are word problems that involve the distance an object will travel at a certain average rate for a given period of time.
The formula for distance problems is: distance = rate × time or d = r × t.
