Answer:

How to find equivalent fractions?

Two fractions are equivalent when they are both equal when written in the lowest terms. The fraction 18/ 20 is equal to 9/ 10 when reduced to the lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (9/ 10 ) by the same integer number, i.e., multiply by 2, 3, 4, 5, 6 ...

18/ 20 is equivalent to 9/ 10 because 9 x 2 = 18 and 10 x 2 = 20

27/ 30 is equivalent to 9/ 10 because 9 x 3 = 27 and 10 x 3 = 30

36/ 40 is equivalent to 9/ 10 because 9 x 4 = 36 and 10 x 4 = 40

and so on ...

At a glance, equivalent fractions look different, but if you reduce then to the lowest terms you will get the same value showing that they are equivalent. If a given fraction is not reduced to lowest terms, you can find other equivalent fractions by dividing both numerator and denominator by the same number.

What is an equivalent fraction? How to know if two fractions are equivalent?

Finding equivalent fractions can be ease if you use this rule:

Equivalent fractions definition: two fractions a/ b and c/ d are equivalent only if the product (multiplication) of the numerator (a) of the first fraction and the denominator (d) of the other fraction is equal to the product of the denominator (b) of the first fraction and the numerator (c) of the other fraction.

In other words, if you cross-multiply (a/ b and c/ d ) the equality will remain, i.e, a.d = b.c. So, here are some examples:

18 /20 is equivalent to 9 /10 because 18 x 10 = 20 x 9 = 180

27/ 30 is equivalent to 9/ 10 because 27 x 10 = 30 x 9 = 270

36/ 40 is equivalent to 9/ 10 because 36 x 10 = 40 x 9 = 360

The equation of the line passing through the points (3, 16) and (5, 10) can be expressed as y = mx + b. Give the value of b

Alenkinab [10]

we are given two points as

(3, 16) and (5, 10)

firstly , we will find slope

slope is m

so, we can use formula

$m=\frac{y_2-y_1}{x_2-x_1}$

now, we can plug points

$m=\frac{10-16}{5-3}$

$m=\frac{-6}{2}$

$m=-3$

we can plug it in y=mx+b

we get

$y=-3x+b$

now, we can select any one points

and find b

(3,16)

x=3 and y=16

$16=-3*3+b$

we can find b

$b=25$

now, we can plug back b

and we get

$y=-3x+25$

so, equation is

$y=-3x+25$

and

$b=25$ ...............Answer

If AC is parallel to DE, find X

UNO [17]

Answer: x = 50

Concept:

Here, we need to know the idea of alternative interior angles and the angle sum theorem.

Alternative interior angles are angles that are formed inside the two parallel lines, and the values are equal.

The angle sum theorem implies that the sum of interior angles of a triangle is 180°

If you are still confused, please refer to the attachment below or let me know.

Step-by-step explanation:

Given information:

AC ║ DE

∠ABC = 85°

∠A = 135°

Find the value of ∠BAC

∠A + ∠BAC = 180° (Supplementary angle)

(135°) + ∠BAC = 180°

∠BAC = 45°

Find the value of ∠BCA

∠ABC + ∠BAC + ∠BCA = 180° (Angle sum theorem)

(85°) + (45°) + ∠BCA = 180°

∠BCA = 50°

Find the value of x (∠EBC)

∠EBC ≅ ∠BCA (Alternative interior angles)

Since, ∠BCA = 50°

Therefore, ∠EBC = 50°

$\Large\boxed{x=50}$

Hope this helps!! :)

A new crew of painters takes two times as long as the old painters. Together they can paint in 6 hours. How many hours does it t

babymother [125]

Let n be old painters time. Then the new painters are 2n. So:
1/n+1/2n=1/6
2+1=2n/6
2n=18
n=9
The old painters take 9 hours; the new ones take 18

24+15+11=50, the total number of times the markers were chosen.

Since 11 of these 50 tries resulted in a red and blue marker, the probability is 11/50. This is equal to 0.22 or 22%.
