Answer:

(2 - x ) = 1 / 10

Step-by-step explanation:

1 / 5 + 2 / 3 (2 - x ) = 4 / 15

Subtract 1 / 5 from both sides

2 / 3 (2 - x ) = 4 / 15 - 1 / 5

2 / 3 (2 - x ) = 1 / 15

Multiply 3 / 2 on both sides

(2 - x ) = 1 / 15 * 3 / 2

(2 - x ) = 1 / 10

Line QR goes through points Q(0,1) and R(2,7). Which equation represents line QR ?
vodomira [7]
(0,1)(2,7)
slope(m) = (7-1) / (2-0) = 6/2 = 3

y = mx + b
slope(m) = 3
use either of ur points...(0,1)....x = 0 and y = 1
now sub and find b, the y int
1 = 3(0) + b
1 = b

so ur equation is : y = 3x + 1....or 3x - y = -1

Mark reads 42 pages of a book every 3/4 hour. Write an equation that models the relationships between x, the number of hours Mar
Illusion [34]

Answer:

The equation that models the relationships between x, the number of hours Mark reads, and , y the number of pages of the book he reads is:

y=56x

Step-by-step explanation:

Given:

Mark reads 42 pages every \frac{3}{4} hour.

The number of hours is given by = x

The number of pages is given by =y

The equation can be modeled as:

y=mx+b

where m represents rate of change and b represents the y-intercept or the initial value.

Rate of change ==\frac{Change\ in\ y}{Change\ in\ x}=\frac{42}{\frac{3}{4}}=42\times \frac{4}{3}=56

The initial value b=0 as Mark starts reading from 0.

So, the equation is:

y=56x

Answer:

the SSS similarity theorem

Step-by-step explanation:

⇒ It cannot be the SAA similarity theorem as they only share a single common angle

⇒ It cannot be the HL similarity theorem, as the sides are not equal

⇒ It must be the SSS triangles

===========================================================

<h3>What is the SSS similarity theorem?</h3>

It states that :

If the lengths of the corresponding sides of two triangles are proportional, then the two triangles are similar.

============================================================

Let's take the sides in proportion :

⇒ 15/5 = 3 (Hypotenuses)

⇒ 6+3/3 = 9/3 = 3 (Heights)

⇒ 8+4/4 = 12/4 = 3 (Bases)

As the sides are in proportion, the triangles are similar by the SSS similarity theorem.
