Answer:
42/9=14/3
Step-by-step explanation:
Simplificación de Fracciones
Una fracción de la forma x/y puede ser representada de infinitas maneras, siempre y cuando produzcan el mismo resultado.
Por ejemplo, las fracciones 5/3 y 10/6 son equivalentes porque producen el mismo resultado. Obsérvese que tanto el numerador como el denominador en la segunda están multiplicados por 2.
Igualmente si tenemos 10/6, podemos obtener 5/3 dividiendo a ambos por 2.
La fracción 42/9 puede convertirse a una fracción equivalente dividiendo ambos términos por 3 para obtener 14/3

Water flows through a pipe at a rate of 2 fluid ounces per second. Express this rate of flow in quarts per minute.
Answer:
Step-by-step explanation:
3.75
Water flows through a pipe at a rate of 3.75 fluid quarts per minute.
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
Water flows through a pipe at a rate of 2 fluid ounces per second.
2 ounces = 0.0625 quarts
And 1 second = 0.0166667 minutes
So, water flows through a pipe at a rate of 0.0625 quarts per 0.0166667 minutes.
Water flows through a pipe at a rate of 3.75 fluid quarts per minute.
Therefore, the rate is 3.75 fluid quarts per minute.

Find the ratio a:b if it is given that ... a+3b/5=a-2b/2. HELP RIGHT NOW PLS
By simplifying the given equation, we can see that the ratio a:b is:
8:1
How to find the ratio a:b?
We start with the equation:
(a + 3b)/5 = (a - 2b)/2
The first thing we need to isolate each variable in one side of the equation.
(a + 3b)/5 = (a - 2b)/2
2*(a + 3b) = 5*(a - 2b)
2a + 6b = 5a - 10b
6b + 10b = 5a - 2a
16b = 2a
So, 16 times b is equal to 2a
We can write this as:
b/2 = a/16
b = a/8
Then the ratio a to b is:
8:1

if Afsheen can read 39 pages of a book in half an hour how much will it take her to finish the book that is 1287 pages
We are given:
Afsheen can read 39 pages in 30 minutes
Time taken by Afsheen to read 1287 pages:
Time taken to read 1 page:
Time taken to read 1 page = time taken to read 39 pages / 39
Time taken to read 1 page = 30 minutes / 39
Time taken to read 1 page = 0.77 minutes
Time taken to read 1287 pages:
Time taken to read 1287 pages = Time taken to read 1 page * 1287
Time taken to read 1287 pages = 0.77 * 1287
Time taken to read 1287 pages = 991 minutes OR 16.52 hours (Approx)
Answer:
in 1 hour = 2×39= 78 pages
so 1287 pages= 1287÷78= 16.5 hours
Step-by-step explanation:
it takes 16. 5 hours that means 16 hours 30 min

What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Equation of line is,
⇒ y - 4 = x - 2
Now, We can simplify for slope as;
⇒ y - 4 = x - 2
⇒ y = x + 2
⇒ dy/dx = 1
⇒ m = 1
Thus, The slope of the line whose equation is y - 4 = (x - 2) is,
⇒ m = 1

4x-3x-12=7
x-12=7
x=7+12
x=19
Answer:
x=19
Step-by-step explanation:
first you would distribute the -3 to the x and the 4 which would give you
4x-3x-12=7
next you would combine like terms (there's always an invisible 1 one front of a variable)
x-12=7
then to get the variable by itself you would add 12 on each side
x=19

How do you solve 7,124 ÷ 26 using standard algorithm?
Answer:
274
Step-by-step explanation:
The standard algorithm of multiplication is based on the principle that you already know: multiplying in parts (partial products): simply multiply ones and tens separately, and add.
However, in the standard way the adding is done at the same time as multiplying. The calculation looks more compact and takes less space than the “easy way to multiply” you have learned.(i really think this is correct but I am so so sooo sorry if it's not!!!!)
A man is lying on the beach, flying a kite. He holds the end of the kite string at ground level and estimates the angle of elevation of the kite to be 55°. If the string is 350 ft long, how high is the kite above the ground? (Round your answer to the nearest foot.)
The kite is approximately 345 feet above the ground.
The height of the kite above the ground is 287 ft
The length of the string, the height of the kite (h) above ground and the perpendicular distance from the end of the kite string to the man forms a right angled triangle.
Trigonometric shows the relationship between the lengths and angles of a right angled triangle.
Therefore using trigonometric ratios:
sin(55) = h / 350
h = 287 ft
Therefore the height of the kite above the ground is 287 ft.
