[tex](8x-17)(5x+19)\\40x^{2}+152x-85x-323\\ 40x^{2}+67x-323[/tex]

Answer:

It is a non -proportional equation

Answer:

a=4

b=-6

Step-by-step explanation:

3(2ax-10)=24x+5b

6ax - 30 = 24x + 5b

6a = 24

a = 4

5b = -30

b = -6

check: 3(2*4*x - 10) = 24x - 30 = 24x + 5 * (-6) = 24x - 30

Answer:

C

Step-by-step explanation:

Answer:

6x+36=11x-9

11x-6x=36+9

5x=45

X=45

now,

45+Z=180

Z=180-45

Therefore,Z=135

6x+36=11x-9

or,11x-6x=36+9

or,5x=44

:X=35

We know that,

45+Z=180

or,Z=180-45

:Z=135

The situation which leads to a unit cost of $4 per hat is 12 hats for $48. Hence, option B is correct.

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.

As per the data given in the question,

Cost of one hat = $4

Cost of 12 hat = $4 × 12 = $48.

Therefore, $48 is the price of 12 hats.

Answer:

The total number of text messages sent was 27.

Step-by-step explanation:

The monthly cost of the cell phone plan, in function of the number of text messages sent(s) and the number of messages received(r), is given by:

[tex]C = 39.95 + 0.15(s + r)[/tex]

In this question, we have that:

[tex]C = 53.45, r = 63[/tex]

We put this into the equation to find the value of s. So

[tex]C = 39.95 + 0.15(s + r)[/tex]

[tex]53.45 = 39.95 + 0.15(s + 63)[/tex]

[tex]0.15s + 9.45 = 13.50[/tex]

[tex]s = \frac{13.50 - 9.45}{0.15}[/tex]

[tex]s = 27[/tex]

The total number of text messages sent was 27.

The number of students having a cell phone if Approximately 4 out of 5 students in Mrs. Haynes 7th grade math class have cell phones, and there are 365 students in the 7th, is 292.

The fundamental concept of making the same number of additions repeatedly is represented by the action of multiplication.

The results of multiplying two or more integers are known as the products, and the factors that are used in the multiplication are referred to as the factors.

Given:

Approximately 4 out of 5 students in Mrs. Haynes 7th grade math class have cell phones, and there are 365 students in the 7th,

Calculate the number of students having a cell phone as shown below,

The number of students having a cell phone = 4 / 5 of 365

The number of students having a cell phone = 4 / 5 × 365

The number of students having a cell phone = 4 × 73

The number of students having a cell phone = 292

Thus, The number of students having a cell phone is 292.

2 * 5 * 6 = 60

Kim rolls three 6 sided dice.  The product of her numbers is 60. So, the numbers are 2, 5, and 6 and this can be determined by using arithmetic operations.

Given :

The following steps can be used to determine the number could Kim has rolled:

Step 1 - Let the three numbers be a,b, and c.

Step 2 - Given that the product of these numbers is 60.

[tex]a\times b \times c = 60[/tex]

Step 3 - So, the possible values of a, b, and c are:

a = 2

b = 5

c = 6

Step 4 - Check the product of a, b, and c if it is 60 then it is correct.

[tex]2\times 5\times 6 = 60[/tex]
