Answer:

$151

Step-by-step explanation:

225 = 74 + m

- subtract 74 from both sides

225-74 = 74-74 +m

1. 151 = 74 - 74 + m

2. 151 = 0 + m

the 0 is irrelevant so you can remove it and you get

151 = m

the correct way to write it would be:

m = 151

THANK YOU

Expression is a set of numbers, variables, and mathematical operations. The standard form of the expression (-7x+5)-(2x²–8x+6) is -2x²+x-1.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

As the expression is given to us (-7x + 5) - (2x² – 8x + 6), in order to simplify the problem we need to open the brackets. therefore, the expression can be solved as,

[tex](-7x + 5) - (2x^2 - 8x + 6)\\\\= -7x + 5 - 2x^2 + 8x - 6\\\\ = -2x^2+8x-7x-6+5\\\\=-2x^2 + x - 1[/tex]

Hence, the standard form of the expression (-7x+5)-(2x²–8x+6) is -2x²+x-1.

Answer:

1650 families

Step-by-step explanation:

In a survey of his neighborhood, Timothy found out that 3 families out of 7 have a dog for a pet.

The given ratio = 3:7

When written as a fraction = 3/7

The number of families that would have a pet dog in a town with about 3,850 families is given as:

3/7 × 3,850

= 1650 families

Therefore, 1650 families would have a pet dog in town.

Step-by-step explanation:

After the arrival of 5 marriages, the total women will be 9.

Function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function

Expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators

Equation : A mathematical equation is used to equate two expressions.

Given is that at a party the number of women was 4 times the number of men after the arrival of 5 marriages the percentage of men at the party became due 6%

Assume that the initial number of men are [x]. Then, the number of women will be y = 4x.

After the arrival of 5 marriages -

y + 5 = 4x + 5

and

x = 6% of y

x = (6/100) x y

x = (3/50)y

So, we can write -

y + 5 = (12/50) + 5

y = 12/50

So -

x = (12/50) x (50/3)

x = 4

After the arrival of 5 marriages, the total women will be -

x + 5 = 9

Therefore, after the arrival of 5 marriages, the total women will be 9.

Answer: The Ferris wheel can hold 576 People in 4 hours

Step-by-step explanation: To find how many people the Ferris wheel can hold in 4 hours, we first want to know how many people the Ferris wheel can hold per minute and per hour.

To find how many people can go on the Ferris wheel per minute, simply divide 60 by 25.

60/25 = about 2.4 people per minute.

There are 60 minutes in a hour, so multiply 2.4 by 60.

2.4 x 60 = 144 People per hour.

We want to know how many people the Ferris wheel can hold in 4 hours. So multiply 144 by 4.

144 x 4 = 576 People that the Ferris wheel can hold in 4 hours.

Answer:

Non-linear

Step-by-step explanation:

Here, we want to determine the function type that would model the height of a football from the time it was kicked to the time it lands on the ground

The way to go about this is to notice the kind of shape or trajectory the kicked football will take.

The shape it will take is non-linear. The shape it will take would be a parabolic curve. These parabolic curve models a quadratic equation and not a linear function. Hence we can conclude that based on the kind of path in which the ball traces, we can conclude that the function that results from its trajectory would not be a linear kind of equation or representation.

Answer: -7, 7

Step-by-step explanation:

-2x^2 - 9 = -107

-2x^2 + 98 = 0 (add 107 to both sides)

-2(x - 49) = 0 (factor out -2)

-2(x - 7)(x + 7) = 0 (factor)

x - 7 = 0

x = 7

x + 7 = 0

x = -7

Step-by-step explanation:

Area of house and garage is at most 3000 ft²

Area of garage = 528 ft²

Area of house (h) =?

Area of garage + Area of house ≤ 3000 ft²

528 ft² + h ≤ 3000 ft²

h ≤ 3000 ft² - 528 ft²

h ≤ 2472 ft²

Answer:

  C

Step-by-step explanation:

You can reflect point x across the origin to find is is just above -1. Adding 3 to that value gives a point just above -1+3 = 2. That's where point C is located.

__

Algebraic solution

Algebraically, you can set y = -x +3, and solve for x. That gives you ...

  x = 3 -y

Using the relation given at the start:

  0 < x < 1

  0 < 3 -y < 1 . . . . . substitute for x

Adding y gives ...

  y < 3 < y+1

We can separate this into two inequalities:

  y < 3, and

  3 < y+1

  2 < y . . . subtract 1

Now, we have ...

  2 < y < 3 . . . . . the location of point C

As you can see, it is much easier to use the number line directly to find the desired point.

Answer:

The rate of change or slope m  = -50

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Given that there is $500 in Holly's bank account.

Thus, the y-intercept b = 500

It is stated that she takes out $50 from her account each month but doesn't put money back in.

It means the rate of change or slope is decreasing.

Thus, the rate of change or slope m  = -50

EXTRA BONUS!

We can also determine the line equation by substituting m = -50 and b = 500 in the slope-intercept form

[tex]y = mx+b[/tex]

y = -50x + 500

Here:

The slope m = -50

The y-intercept = 500

Given :

The four sides of a garden measure 8 1/3 feet, 17 1/4 feet, 17 1/2 feet, and

11 3/4 feet.

To Find :

The length (in ft) of the fence needed to enclose the garden.

Solution :

First simplifying the given mixed numbers :

8 1/3 = 25/3 feet

17 1/4 = 69/4 feet

17 1/2 = 35/2 feet

11 3/4 = 47/4 feet

Now, length of fence needed to enclose the garden is :

[tex]L = \dfrac{25}{3}+ \dfrac{69}{4}+ \dfrac{35}{2}+ \dfrac{47}{4}\\\\L = \dfrac{(25\times 4)+ ( 69\times 3) + ( 35\times 6) + (47 \times 3 )}{12}\\\\L = \dfrac{658}{12}\ feet[/tex]

Hence, this is the required solution.

Answer:

y = - x + 2

Step-by-step explanation:

the slope is negative, so eliminate choice 2 and 3.

the y intercept is 2 and the slope is -1, hence the answer is choice 4
