Answer:

- 51

Step-by-step explanation:

Order of operations. What's in the parenthesis is first.

4 + 3 ( 7+4 x 2) - 100  

Concentrate on (7 + 4 x 2 ) first.

We multiply first so 4 x 2 = 8  then we add.

(7 + 8) = 15

4 + 3(15) - 100    Again, we multiply first.

4 + 45 - 100      Now we can add and subtract in any order.

49 - 100 = - 51

Answer:

You can buy approximately 6.6 gallons of milk.

Step-by-step explanation:

We can solve this problem by making a proportion:

4.61 gallons/$14.86 = x gallons/$21.32

By cross-multiplying, we get:

4.61 × 21.32 = 14.86x

98.29 = 14.86x

x = 6.6 gallons

Answer: 8 weeks

explanation: 125 + 15x = 245

You then have to subtract 125 from both sides so we can isolate our variable which will give us 15x = 120 . Divide 15 from both sides : 15x/15 = 120/15 which will give us x = 8.

Answer:

SF = 39

Step-by-step explanation:

Answer:

x=6

Step-by-step explanation:

1. First, distribute the numerator. That leaves you with:

[tex]\frac{6x-12}{12} =\frac{2x+2}{7}[/tex]

2. Now, cross multiply. You should have:

[tex]7(6x-12)=12(2x+2)[/tex]

3. Next, simplify and solve the equation for x. You should have:

[tex]7(6x-12)=12(2x+2)[/tex]

[tex]42x-84=24x+24\\42x=24x+108\\18x=108x=6[/tex]

Answer:

Options 1, 2, and 5 are the correct ones

Step-by-step explanation:

Answer:

Lets start with the given system of linear equations In order to solve for one variable, we must eliminate the other variable. So if we wanted to solve for y, we would have to eliminate x (or vice versa). So lets eliminate x. In order to do that, we need to have both x coefficients that are equal but have opposite signs (for instance 2 and -2 ...

Answer:

Begin at the point, draw a vertical line either up or down to the x-axis to get the x-coordinate.

Begin at the point, draw a horizontal line either to the left or right of the y-axis to get the y-coordinate.

Step-by-step explanation:

In a two-dimensional plane, coordinates of a point define its exact location. The coordinate plane has two axes that are perpendicular to each other which are known as the x and y axis.

To find out the coordinates of a point in the coordinate system, follow the following procedure.

Begin at the point, draw a vertical line either up or down to the x-axis to get the x-coordinate.

Begin at the point, draw a horizontal line either to the left or right of the y-axis to get the y-coordinate.

The x-coordinate and the y-coordinate determine the new coordinates of a point.

Answer:

D. 54 degrees

Step-by-step explanation:

subtract 72 from 180 and divide by 2

If you have negative numbers anywhere in the set, then that set cannot be part of the whole numbers or natural numbers. This is because

set of whole numbers = {0,1,2,3,4,5,...}

set of natural numbers = {1,2,3,4,5,...}

The only difference is that 0 is not included in the set of natural numbers. Neither set has negative values in them.

So for instance the set {-5, 1,2,7} involves a number that is neither part of the whole numbers or natural numbers set. But every item listed is an integer

set of integers = { ..., -3, -2, -1, 0, 1, 2, 3, ... }

We can see that the integers is the set of positive and negative whole numbers, with 0 as well

Answer:

All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.

Answer:

A.point W

Step-by-step explanation:

The point that describes the intersection of line m and line n is point W. The correct option is A.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.

As it is given that Line m intersects line n at point W. Therefore, The point that describes the intersection of line m and line n is point W. Thus, the correct option is A.

Answer:

The minimum thickness of the book is 53.8mm

Step-by-step explanation:

Given units/terms

Solution:

(0.9mm)(2) + (0.13mm)(400) = 1.8 mm + 52.mm = 53.8mm

Answer:

min. thickness of the book is 53.8mm

Step-by-step explanation:

400 pages, each page thickness = 0.13mm

front and back cover thickness = 0.9mm

total thickness of the book = front + 400 pages + back cover

total = 0.9 + (400 x 0.13) + 0.9

total = 0.9 + 52 + 0.9

total = 53.8 mm

Answer:

-9h² - 12h - 3

Step-by-step explanation:

Follow the FOIL method:

FOIL = First, Outside, Inside, Last

Multiply the terms together:

First: 9h * -h = -9h²

Outside: 9h * -1 = -9h

Inside: 3 * -h = -3h

Last: 3 * -1 = -3

Combine like terms: 9h² + (-9h - 3h) - 3

9h² - 12h - 3

-9h² - 12h - 3 is your answer.
