Answer:

42 - 14x = 9

Step-by-step explanation:

Given

2 - [tex]\frac{2}{3}[/tex] x = [tex]\frac{3}{7}[/tex]

Multiply through by 21 ( the LCM of 3 and 7 ) to clear the fractions

42 - 14x = 9 ← with no fractions

Answer:

14x - 33 = 0

Step-by-step explanation:

2 - (2/3) x = 3/7

6 - 2x = 9/7 (multiply 3)

42 - 14x = 9 (multiply 7)

14x - 33 = 0

Some Equations:

6 + x = 27

x + 6 = 27

27 - 6 = x

27 - x = 6

27 = x + 6

27 = 6 + x

There are 11 girls

A system of equations to model this statement is x + (x + 6) = 27.

A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.

Given, There are 6 more boys than there are girls.

Assuming no. of girls to be x, therefore no. of boys is (x + 6).

Mrs. Smith has a total of 26 kids in her class.

∴ x + (x + 6) = 27.

Step-by-step explanation:

30÷100×640=192

total income =160+192

=352

weekly sales=?(x)

wage=640

so...

x×0.3+160=640

0.3x=640-160

0.3x=480

x=480÷0.3

Answer:

Multiply the bottom equation by 2.

Step-by-step explanation:

The given equation are:

3x + 4y = 8

and 6x – 2y = 9

(1)

(2)

Now, in order to add these equations and eliminate y, we should multiply the bottom equation by 2, thus we have

3x + 4y = 8

12x – 4y= 18

(3)

(4)

Now, adding the above equations, we

have

15x 26

= 26 15

Now, substituting the value of x in equation (3), we have

3(25) + 4y=8

y=1

A.P.E.X 2021

Answer:

1500

Step-by-step explanation:

we can write the 4-digit PIN as ABCD

A = factor of 10 so,

A = 1, 2 ,5 (3 possible number or we can write n(A) = 3

B and C are number from 0 - 9 so each have 10 possible number n(B) = 10 and n(C) = 10

D makes the whole number cannbe divide by 2. it means that D must even number 2,4,6,8 or 0. so there are 5 possible number n(D) = 5

so to find how many different sets we just multiply all possible number

n(A) x n(B) x n(C) x n(D)

3 x 10 x 10 x 5 = 1500 different sets

Step-by-step explanation:

The number of days Super Sally and Lazy Petunia work are illustrations of simultaneous equations

(a) Super Sally and Lazy Petunia

Represent their earnings with the first letters.

So, we have:

[tex]\mathbf{L = \frac 12S}[/tex] -- number of days

[tex]\mathbf{20L + 57S= 7733}[/tex] --- the total earnings

Make S the subject in [tex]\mathbf{L = \frac 12S}[/tex]

[tex]\mathbf{S = 2L}[/tex]

Substitute 2L for S in [tex]\mathbf{20L + 57S = 7733}[/tex]

[tex]\mathbf{20L + 57 \times 2L = 7733}[/tex]

Expand

[tex]\mathbf{20L + 114L = 7733}[/tex]

Add

[tex]\mathbf{134L = 7733}[/tex]

Divide both sides by 134

[tex]\mathbf{L = 57.7}[/tex]

From the options, the closest to 57.7 is 60.

Hence, the number of days that Petunia worked is closest is 60

(b) 4 digit even numbers

The digits are given as: 0, 1, 5, 6, 7, 8 and 9

To create a 4-digit number, the first digit cannot be 0.

So, the first digit can be any of the remaining 6

Because, it is an even number, the number can only end with 0, 6 or 8

So, the last digit can be any of the 3

Since there is no repetition, the second and the third digits can be any of the remaining 5 and 4 digits, respectively.

So, the number of digits is:

[tex]\mathbf{n =6 \times 3 \times 5 \times 4}[/tex]

[tex]\mathbf{n =360}[/tex]

Hence, the number of digits is (d) 360

(c) The value of 28^983 x 98^984/14^2948

Rewrite the expression as:

[tex]\mathbf{\frac{28^{983} \times 98^{984}}{14^{2948}}}[/tex]

Express all number as a base of 14

[tex]\mathbf{\frac{14^{2 \times 983} \times 14^{7 \times 984}}{14^{2948}} }[/tex]

Apply law of indices

[tex]\mathbf{14^{2 \times 983+7 \times 984-2948}}[/tex]

Evaluate all products

[tex]\mathbf{14^{1966+6888-2948}}[/tex]

Evaluate the exponent

[tex]\mathbf{14^{5906}}[/tex]

Hence, the result of [tex]\mathbf{\frac{28^{983} \times 98^{984}}{14^{2948}}}[/tex] is [tex]\mathbf{14^{5906}}[/tex]

Answer:

The equation of the line that passes through the given points is:

Hence, option D is correct.

The graph of the line equation is also attached below.

Step-by-step explanation:

Given the points

Finding the slope between (-5, 10) and (5, -10)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-5,\:10\right),\:\left(x_2,\:y_2\right)=\left(5,\:-10\right)[/tex]

[tex]m=\frac{-10-10}{5-\left(-5\right)}[/tex]

[tex]m=-2[/tex]

Using the point-slope form to determine the line equation

Point slope form:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = -2 and the point (-5, 10)

[tex]y-10=-2\left(x-\left(-5\right)\right)[/tex]

[tex]y-10=-2\left(x+5\right)[/tex]

Add 10 to both sides

[tex]y-10+10=-2\left(x+5\right)+10[/tex]

simplify

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

Thus, the equation of the line that passes through the given points is:

Hence, option D is correct.

The graph of the line equation is also attached below.

Answer:

We conclude that the range of the function will be:

R = {5, 17, 29}

Step-by-step explanation:

Given

Given the function

f(x) = 6x-1

Given the domain

D = {0, 3, 5}

To Determine:

The range R = ?

We know that range of the function consists of all the y-values for the x-values in the domain of the function.

so substituting the values of x = 0, 3, and 5 in the function to determine the corresponding y-values.

Plug in x = 0

y = 6x-1

y = 6(0) - 1 = 6-1 = 5

Plug in x = 3

y = 6x-1

y = 6(3) - 1 = 18-1 = 17

Plug in x = 5

y = 6x-1

y = 6(5) - 1 = 30-1 = 29

Now, combine all the determined y-values which are 5, 17, and 29.

Therefore, we conclude that the range of the function will be:

R = {5, 17, 29}

Answer:

64

Step-by-step explanation:

Here, we want to know the sum of the next two terms

We need to get the pattern first

The difference between the first two numbers is 49 (7^2)

next two is 36 (6^2)

next two is 25 (5^2)

next two is 16 (4^2)

next two will be 3^2 = 43-9 = 34

next will be 2^2 = 34-4 = 30

So the sum here is 30 + 34 = 64

Answer:

The following statements are true

(2)(6) > (–2)(2)

6/-2 < -2/-2

6/2 > -2/2

Step-by-step explanation:

Missing options

(2)(6) > (–2)(2)

6/2 < -2/2  

(–2)(6) > (–2)(–2)

6/-2 < -2/-2

(2)(6) < (–2)(2)

6/2 > -2/2

Before we know which statement is true, you must understand that when both sides of an inequality is multiplies or divided by a negative number, the inequality sign reverses.

For the first option:

6 > -2

Multiplying both sides by 2 will not reverse the inequality sign

Hence 2(6)>2(-2) is true since the inequality was retained.

For the second option:

6/2 < -2/2  

Dividing both sides by 2 will not reverse the inequality sign

Hence 6/2>2/2 is true nullifying the given expression 6/2 < -2/2  . Hence this expression is false

For the third option:

(–2)(6) > (–2)(–2)

Both sides were multiplied by a negative number i.e -2. Hence the sign supposed to reverse because -12 > 4 is false therefore this expression is FALSE

For the fourth option

6/-2 < -2/-2

Both sides were divided by a negative number i.e -2. Hence the sign supposed to reverse because -3 < 1 is true, therefore this expression is TRUE

For the fifth option:

((2)(6) < (–2)(2)

Both sides were multiplied by a positive number i.e 2. Hence the sign is not supposed to reverse because 12 < -4 is False, therefore this expression is FALSE

For the sixth option:

6/2 < (–2)/2

Both sides were divided by a positive number i.e 2. Hence the sign is not supposed to reverse because 3 < -4 is TRUE, therefore this expression is TRUE
