Answer:

$3\left(5+4y\right)+8-2y=10y+23$

Step-by-step explanation:

Given

As the expression is given by

$3(5+4y)+8-2y$

To determine

Simplify the expression

Let us simplify the expression

$3(5+4y)+8-2y$

Expand 3(5 + 4y) = 15 + 12y

$3\left(5+4y\right)+8-2y=15+12y+8-2y$

grouping like terms

$=12y-2y+15+8$

$=10y+23$

Therefore,

$3\left(5+4y\right)+8-2y=10y+23$

Juli2301 [7.4K]

Answer:

Step-by-step explanation:

h and p are the number of history and psych textbooks, respectively.

store sold a total of 411 textbooks in a week.

h + p = 411

The number of history textbooks sold was 69 less than the number of psychology textbooks sold.

h = p - 69

Substitution

(p-69) + p = 411

2p = 411+69

p = 240

h = p-69 = 171

171 history books and 250 psych books

On a coordinate plane, triangles P Q R and S T U are shown. Triangle P Q R has points (4, 4), (negative 2, 0), (negative 2, 4).

mamaluj [8]

Answer:

The answer is below

Step-by-step explanation:

Two triangles are said to be similar if their corresponding angles are equal and the corresponding sides are in proportion.

The distance between two points on the coordinate plane is given as:

$Distance=\sqrt{(x_2-x_1}^2+(y_2-y_1)^2 \\\\Therefore\ in\ triangle\ PQR:\\\\|QR|=\sqrt{(-2-(-2))^2+(4-0)^2}=4\\\\|PQ|=\sqrt{(-2-4)^2+(0-4)^2}=\sqrt{52}=2\sqrt{13} \\\\|PR|=\sqrt{(-2-4)^2+(4-4)^2}=6$

In triangle STU:

$|ST|=\sqrt{(-1-2)^2+(-2-(-4))^2}=\sqrt{13}\\\\|SU|=\sqrt{(-1-2)^2+(-4-(-4))^2} =3\\\\|TU|=\sqrt{(-1-(-1))^2+(-4-(-2))^2}=2$

|QR| / |TU| = 4/2 = 2

|PR| / |SU| = 6/3 = 2

|PQ| / |ST| = 2√13 / √13 = 2

Hence:

|QR| / |TU| = |PR| / |SU| = |PQ| / |ST|

Therefore, △PQR and △STU are similar triangles since the ratio of their sides are in the same proportion.

A city contains 100,000 people (45,000 males and 55,000 females), and 1,000 people die per year (600 males and 400 females). The

vitfil [10]

Answer:a)0.001

b) males=1.

Females = 1

c) 0.9

d) 4×10^-5

e)0.045

Step-by-step explanation:a) crude death= Number of death/Number of individuals = 1000/100000= 0.001

b)sex specific death rate= numbered deaths of males/ number of deaths of males= 600/600= 1

c)case specific = 45/50=0.9

d)cause specific= Number of people dying from lung cancer/number of people with disease=45/100000=4×10^-5

e) pmr= number of deaths from specific disease÷total number of death=45/1000=0.045
