Answer and Step-by-step explanation:

3x + 7 + 10x = 7 + 13x + 10

13x + 7 = 13x + 17

0 = 10

No solutions

-6x -6 + 8x = -5 + 2x -1

2x - 6 = -6 + 2x

0 = 0

Many solutions.

The first equation has no solutions.

The second equation has infinitely many solutions.

Answers:

1. No solutions

2. Infinitely many solutions

Step-by-step explanation:

[tex]3x+7+10x=7+13x+10[/tex]

Add common terms from both sides of the equation (10x and 3x) & (7 and 10)

[tex]13x+7=17+13x[/tex]

Subtract common terms from both sides (13x and 13x)

[tex]7\neq 17[/tex]

7 does not equal 17; thus, there are no solutions

[tex]-6x-6+8x=-5+2x-1[/tex]

Add common terms from both sides of the equation (-6x and 8x) & (-5 and -1)

[tex]2x-6=-6+2x[/tex]

Reorder the right side of the equation

[tex]2x-6=2x-6[/tex]

Since this is a true statement, there are infinitely many solutions

Step-by-step explanation:

Given that,

No. of chocolate chip cookies = 86

No. of sugar cookies = 42

We need to find the number of identical packages that I can make.

It means we need to find the HCF of these 2 number.

Prime factorization of 86 and 42 as follows :

86 = 2 x 43

42 = 2 x 3 x 7

HCF = 2

Hence, I can make 2 identical packages.

Answer:

Assuming there can only be 2 cookies per identical package, She can make 42 identical packages which contains 2 chocolate chip cookies and 1 sugar cookie.

86 / 2 = 43 chocolate chips cookies

42 / 1 = 42 sugar cookies

With the sugar cookies not having the capability to match the requirements we will assume for this answer that an "Identical Package" is composed of 2 chocolate chip cookies, and a single sugar cookie.

Answer:

Option B. f¯¹(x) = ³√(– x – 9)

Step-by-step explanation:

From the question given above:

f(x) = – x³ – 9

f¯¹(x) =?

We can obtain the inverse f¯¹(x) of the above equation by doing the following:

f(x) = – x³ – 9

Replace f(x) with y

y = – x³ – 9

Interchange x and y

x = – y³ – 9

Make y the subject . This is illustrated below:

x = – y³ – 9

Rearrange

x + 9 = – y³

Multiply through by –1

–(x + 9) = y³

y³ = – x – 9

Take the cube root of both side

y = ³√(– x – 9)

Replace y with f¯¹(x)

f¯¹(x) = ³√(– x – 9)

Thus, the inverse of the function

f(x) = – x³ – 9

is

f¯¹(x) = ³√(– x – 9)

Answer:

[tex]Perimeter = 34cm[/tex]

Step-by-step explanation:

Given

Represent the adjacent sides with A and B

[tex]A= 7cm[/tex]

[tex]B = 10cm[/tex]

Required

Determine the perimeter

The perimeter is calculated as follows;

[tex]Perimeter = 2 * (L + B)[/tex]

[tex]Perimeter = 2 * (7cm + 10cm)[/tex]

[tex]Perimeter = 2 * (17cm)[/tex]

[tex]Perimeter = 2 * 17cm[/tex]

[tex]Perimeter = 34cm[/tex]

Step-by-step explanation:

-11d - 13d = 22 - 6

-24d = 16

Answer:

x=2

Step-by-step explanation:

9x+9=25+x

subtract 9 on both sides

9x=16+x

subtract x on both sides

x=2

The solution of equation 9(x + 1) = 25 + x is x =2, which is option A.

An equation is a pair of algebraic equations with the equal sign (=) in the middle and the same value.

Given information:

The equation is 9(x + 1) = 25 + x.

To solve for x, we need to isolate x on one side of the equation.

9(x + 1) = 25 + x

First, we can distribute the 9:

9x + 9 = 25 + x

Next, we can simplify by subtracting x and 9 from both sides:

8x = 16

Finally, we can solve for x by dividing both sides by 8:

x = 2

Therefore, the solution is x = 2.

Answer:

a = 6, b = 8

Step-by-step explanation:

given (2,1)

2a - 1b = 4

-1a + 2b = 10

this gives us:

a + b = 14

solve for a

a = 14 - b

plug into first equations

2(14-b) - b = 4

28 - 2b - b = 4

28 - 3b = 4

24 = 3b

b = 8

now plug b back into your equation for a, and you get:

a = 14 - 8

a = 6

Step-by-step explanation:

1/2 divided by 1/4 rewritten is 1/2 times 4/1 equels 4/2. In its simplest form 2.

1/2 divided by 1/4 in the simplest form is 2.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into same number of parts.

Given that the expression 1/2 divided by 1/4.

simplifying,

1/2 divided by 1/4  = 1/2 ÷ 1/4

Rearranging into the multiplication form,

1/2 divided by 1/4 = 4/2

1/2 divided by 1/4 = 2

Answer: 145

Step-by-step explanation:

Given:

58 = 40%(x)

Step 1: Turn 40% into a decimal and divide it to the other side

When turning a percentage into a decimal, the decimal point has to be moved two places to the left.  This means that 40% will be turned into 0.4.

58 = 0.4(x)

Divide 0.4 over to the other side.

58/0.4 = 0.4/0.4(x)

0.4 is the same as 4/10.  This means that 58/1 is divided by 4/10.  When dividing a number by a fraction, you invert the fraction and multiply it by the number.

58/1 * 10/4 = 580/4 = 145

145 = x
