Answer:

blank = - 3

Step-by-step explanation:

let x represent the blanks , then

[tex]\frac{2}{3}[/tex] ([tex]\frac{9}{5}[/tex] + x) = [tex]\frac{2}{5}[/tex] x + [tex]\frac{2}{5}[/tex]

multiply through by 15 ( the LCM of 3 and 5 ) to clear the fractions

10([tex]\frac{9}{5}[/tex] + x) = 6x + 6 ← distribute parenthesis on left side

[tex]\frac{90}{5}[/tex] + 10x = 6x + 6

18 + 10x = 6x + 6 ( subtract 6x from both sides )

18 + 4x = 6 ( subtract 18 from both sides )

4x = - 12 ( divide both sides by 4 )

x = - 3

The jumbo cans of frosting would she need to frost 280 cupcakes is 8 cans.

Addition simply means the sum of the numbers that are given.

In this case, Bette used 3 jumbo cans of frosting to frost 105 cupcakes for the cupcake challenge at her school and 5 jumbo cans of frosting to frost an additional 175 cupcakes. This implies that the total cupcakes will be:

= 105 + 175 = 280

In this case, the cans used will be the addition of the cans above. This will be:

= 3 + 5

= 8 cans

This shows the concept of addition.

A linear equation is a mathematical form of a line segment the point (6,5) satisfies the equation y = 2/3x + 1 so it is the solution of the equation but (9,8) is not the solution.

A straight line on the coordinate plane is represented by a linear function.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

As per the given linear equation, y = 2/3x + 1

To be a point of its solution the point must satisfy the given equation.

Substitute (6,5)

5 = (2/3)6 + 1

5 = 2(2) + 1 = 5

Therefore, the (6,5) is the solution of the equation.

Substitute,(9,8)

(2/3)9 + 1 = 7

8 ≠ 7

So,(9,8) is not the solution of the equation.

Hence "A linear equation is a mathematical form of a line segment the point (6,5) satisfies the equation y = 2/3x + 1 so it is the solution of the equation but (9,8) is not the solution".

If p and q vary inversely and p is 5 when q is 4, the value of q when p is equal to 10 is 2.

An inverse variation can be defined as a type of proportionality which shows the relationship that exist between two (2) distinct variables, wherein, as the value of one variable increases, the value of the other variable decreases and vice-versa.

Mathematically, an inverse variation can be modeled or represented by this expression:

p ∝ 1/q

p = k/q

Where:

Next, we would determine the constant of proportionality (k) by substituting the value of the given variable as follows:

k = pq

k = 5(4)

k = 20

Now, we can determine the value of q:

q = k/p

q = 20/10

q = 2.

If we solve for the value of x we find that x is any value which is greater than -36/11.

What are inequalities ?

When two values are compared , an inequality represents whether one is greater than, less than, or not equal to the other.

It is given in question that a required number divided by 3 decreased by 7 is less than 4 times the number increased by 5.

Let's assume the number be x.

So , x divided by 3 is x / 3 and if we subtract it by 7 , we get :

x/ 3 - 7  

Also , this value is less than 4 times the number added with 5.

i.e.,

4x + 5

So , the inequality can be written as :

[tex]\frac{x}{3}[/tex] - 7 < 4x + 5

or

x - 21  <  12x + 15

-36 < 11x

or

-36 /11 < x

or

x > -36/11

or

x is greater than -36/11.

Therefore , if we solve for the value of x we find that x is any value which is greater than -36/11.

x           /AM/

14          16

3            13

11           33

10           40

/AM/ + /AC/ = /AC/

(x + 2) + (3x - 9) = 6x - 21

4x - 7 = 6x - 21

6x - 4x = 21 - 7

2x = 28

x = 28 / 2

x = 14

/AM/ = 14 + 2 = 16

/AM/ + /MW/ = /AW/

(2X + 7) + (3x - 4) = 18

5x + 3 = 18

5x = 18 - 3

5x = 15

x = 15/5

x = 3

/AM/ = (2 X 3) + 7 =

= 6 + 7 = 13

x + x + x + x = 44

4x = 44

x = 44 / 4

x = 11

/AM/ = 11 x 3 = 33

/AG/ + /GM/ = /AM/

2(x + 10) = 3x + 10

2x + 20 = 3x + 10

20 - 10 = 3x - 2x

10 = x

/AM/ = (3 x 10) + 10

The description of the error in finding the slope and y-intercept, of the graph of the equation is given by the option:

To be in slope-intercept form, the equation needs to be solved for y, not x

The equation in slope-intercept form is,  [tex]\displaystyle{y = -\frac{1}{4} \cdot x[/tex]

The slope-intercept form of the equation of a straight line is an equation of the form, y = m·x + c

The slope-intercept form of a straight-line equation is of the form, y = m·x + c, where:

m = The slope of the equation

c = The y-intercept

The given equation is x = -4·y

The given equation is not in the slope and intercept form given that the subject of the equation is x, rather than y

The error is therefore, in making x, the subject of the equation rather than y, that is the equation needs to be solved for y, not x

The correction of the error is performed as follows:

x = -4·y

-4·y = x

[tex]\displaystyle{y = \frac{x}{-4} = -\frac{1}{4} \cdot x[/tex]

Which gives: [tex]\displaystyle{y = -\frac{1}{4} \cdot x[/tex]

The slope of the graph of the equation is [tex]-\frac{1}{4}[/tex], the y-intercept, c, is 0

1. each ounce of fruit will supply zero units of protein, 3 units of carbohydrates, 2 units of fat and will contain 20 calories

2. each ounce of nuts will supply 3 units of protein, 2 units of carbohydrates and 4 units of fat, and will contain 50 calories

3. Every package must provide at least 9 units of protein, at least 18 carbohydrates, and no more than 22 units of fat

To get at least 9 units of protein, we take at least 3 ounces of nut

3 ounces of nut will give 3 times each unit, and they are as follows

Another restriction is no more than 22 units of fat and we have 12 already remaining 10 units of fat

fruits has lesser calories hence we use it to get the required fats
