Answer:
20
Step-by-step explanation:
There are two ways you can solve this:
1) you can multiply across. We know that 12x5=60 so we can do 4x5 to get 20.
2) also, you can cross multiply. Multiply 60x4=240 and then divide 240 by 12 to get 20.
Hope this helps:)

A line passes through the points (2, -4) and (4, 2). What is the equation of this line in slope-intercept form?
A. y = 3x – 10
B. y = 2x – 14
C. y = 3x + 14
D. y = x + 4
Answers
Answer:
C. y = 3x + 14
Hope it helps!!!Brainliest pls!!!Answer:
A. y = 3x – 10
Step-by-step explanation:
We have equation of line passing through two points (x1, y1) and (x2, y2) as,
(y - y1) = [(y2 - y1)/(x2 - x1)] (x - x1)
(y + 4) = [(2 + 4)/(4 - 2)] (x - 2)
(y + 4) = (6/2)(x - 2)
(y + 4) = 3(x - 2)
3x - y - 10 = 0 --- (1)
Now, slope-intercept form of line is y = mx + c
Rearranging equation (1) ⇒ y = 3x - 10
Therefore, the required equation is y = 3x - 10

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Missy’s sister,Jolly the Carpenter has 10 orders that she needs to finish in 24 hours. She has to make a table which will take her 1.5 hours,a rocking horse which will take 45 mins,a rocking chair which will take 50 mins,2 chairs which will take 54 minutes each,a duck call which will take 30 mins,a wooden car toy which will take 45 mins ,a huge boat which will take 5 hours,and a tiny toy table which will take 15 minutes. How many minutes will she have left over ?
Answers
Let's convert all the times to minutes for easier calculations.
1.5 hours = 90 minutes
45 minutes = 45 minutes
50 minutes = 50 minutes
54 minutes = 54 minutes
30 minutes = 30 minutes
45 minutes = 45 minutes
5 hours = 5 x 60 = 300 minutes
15 minutes = 15 minutes
To find the total time Jolly will spend on all the orders, we add up all the times:
90 + 45 + 50 + 54 + 54 + 30 + 45 + 300 + 15 = 683 minutes
Jolly has 24 hours = 24 x 60 = 1440 minutes to complete all the orders. To find out how many minutes she will have left over, we subtract the total time she will spend on the orders from the total time available:
1440 - 683 = 757 minutes
Therefore, Jolly will have 757 minutes left over after completing all 10 orders.

A small pot holds 75% as much as a large pot.
If a small pot holds 36 units, how much does the large pot hold?
Answers
Answer:
63 units!!
Step-by-step explanation:
36x.75= 27
Add 27 to 36 to get the large pot.
Answer:
The large pot can hold 48 units of water.
Step-by-step explanation:
small pot holds 75% water of a large pot
small pot holds 36 units
let x be quantity of water in large pot
According to the question,
75% of x = 36 units
75/100 * x= 36
75x/100= 36
75x= 36*100
75x= 3600
x= 3600/75
x= 48 units
The large pot can hold 48 units of water.

A pitcher contains 14.25 cups of iced tea. You drink 2.5 cups of the tea each morning and 2.25 cups of the tea each evening. When will you run out of iced tea?
Answers
Answer:
You will run out of iced tea in 3 days (a total of 3 mornings and 3 evenings)
Step-by-step explanation:
Day 1 - 9.5 cups left
14.25 - 2.5 - 2.25 = 9.5
Day 2 - 4.75 cups left
9.5 - 2.5 - 2.25 = 4.75
Day 3 - 0 cup left
4.75 - 2.5 - 2.25 = 0
Answer: You will run out of iced tea in 3 days
Step-by-step explanation:
2.5 + 2.25 = 4.75
14.25/4.75 = 3
Which expression is equivalent to -1/3 ( 6x + 15 ) - 3?
a) -2x + 12
b) -2x + 2
c) -2x - 2
d) -2x - 8
Answers
The correct answer is (D) -2x - 8.
To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:
-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3
Then we can simplify using the properties of multiplication and division:
-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3
Finally, we can combine like terms:
-2x - 5 - 3 = -2x - 8
The correct answer is therefore (D) -2x - 8.✅

The least value of the variable 'm' will be 15. Then the correct option is C.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
If m is a positive integer. And the least value of m for which 225 is a factor of 120m.
Then the factor of the number 225 will be given as,
225 = 3 x 3 x 5 x 5
Then the factor of the number 120m will be given as,
120m = 2 x 2 x 2 x 3 x 5 x m
The least value of 'm' will be given as,
⇒ 3 x 5
⇒ 15
The least value of the variable 'm' will be 15. Then the correct option is C.
