What equation is equivalent to ax-y=b

Answer:

20

Step-by-step explanation:

Given the expression

x(x + 3) + 2 for x = 3

Substitute x =3 into the equation

f(3)= 3(3+3)+2

f(3) = 3(6)+2

f(3) = 18+2

f(3) =20

Hence the value of the expression when x = 2 is 20

Answer:

3/8

Step-by-step explanation:

Given that

Number of clown fish = 10

Number of Angel fish = 4

Number of Puffer fish = 6

Number of Eels = 5

From the above, there exists 10 + 4 + 6 + 5 number of fishes

There exists 25 number of fishes.

Probability of picking a clown fish then is

C = 10 / 25

If the clown fish picked isn't replaced, then there exists 9 clown fishes, and 24 total fishes. This, the probability of picking another clown fish is

C = 9 / 24

C = 3 / 8

Thus, the answer is 3/8

Answer:

Here u go

Step-by-step explanation:

1. 40/100 × 129.50 = 51.80

2. 129.50 - 51.80 = 77.70

3. 15/100 × 77.70 = 11.66

4. 77.70 + 11.66 = 66.04

The final cost of the roller blades is $ 89.66

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total cost of purchase be = A

Now , the initial cost of roller blades = $ 129.50

The discount percentage of roller blades = 40 %

So , the equation will be

The cost of the roller blades after discount = 129.50 - ( 40/100 ) x 129.50

                                                                        = 129.50 - 51.8

                                                                        = $ 77.7

Now ,

The sales tax percentage of roller blades = 15 %

So , the equation will be

The cost of roller blades after sales tax = 77.7 + ( 15/100 ) x 77.7

                                                                  = 77.7 + 11.655

                                                                  = $ 89.655

Therefore , the final cost is A = $ 89.66

Hence , The final cost of the roller blades is $ 89.66

Answer:

[tex] \frac{3}{8} [/tex]

Step-by-step explanation:

First, you add up the amount of students.

[tex]1250 + 750 = 2000[/tex]. Now, you take 750 (crabwrey bog) and divide it by 2000 (the total). Keep simplifying until you can't anymore.

[tex] \frac{750}{2000} = \frac{75}{200} = \frac{15}{40} = \frac{3}{8} [/tex]

So the fraction of students who preferred cranberry bog is

[tex] \frac{3}{8} [/tex]

Answer:

750/2000

Step-by-step explanation:

1250+750=2000 and the focus is cranberry bog so 750/2000 is the answer

The number of tickets to purchase 30 corn dogs is 240.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The number of tickets for 56 corn sold = 448.

This means,

56 corn = 448 tickets

Divide both sides by 56.

1 corn = 8 tickets.

Now,

The number of tickets for 30 corn dogs.

= 8 x 30

= 240 tickets.

Thus,

240 tickets are needed to purchase 30 corn dogs.

Answer:

a = 49°

Step-by-step explanation:

From the figure attached,

In ΔBOC,

OB = OC = Radii of the circle O

Therefore, m∠OBC = m∠OCB = 41° [Opposite angles of the equal sides of a triangle]

By triangle sum theorem,

m∠OBC + m∠OCB + m∠BOC = 180°

41° + 41° + m∠BOC = 180°

m∠BOC = 180° - 82°

              = 98°

Since, "angle subtended by an arc at the center is twice the angle subtended at the circumference",

m∠BOC = 2(m∠BAC)

98° = 2(a)

a = 49°

Answer:

Neither, they have the same amount now?

Step-by-step explanation:

Sally = £450 = 100%

Gone up by 30% so 100% + 30% = 130% = 1.3

£450 x 1.3 = £585

Susie = £650 = 100%

Gone down by 10% so 100% - 10% = 90% = 0.9

£650 x 0.9 = £585

Answer:

Solving the similar triangles, we get x=10.6, y=66

Step-by-step explanation:

The triangles are similar.

We need to find the values of x and y

If the triangles are similar, the ratio of corresponding sides is equal.

So, we can write:

[tex]\frac{32}{x}=\frac{30}{10}=\frac{y}{22}[/tex]

Now, we can solve to find value of x and y

First solving to find value of x:

[tex]\frac{32}{x}=\frac{30}{10}\\Cross \:multiply\\32\times 10=30x\\320=30x\\x=\frac{320}{30}\\x=10.6[/tex]

So, we get x = 10.6

Now, finding value of y:

[tex]\frac{30}{10}=\frac{y}{22}\\Cross\:Multiply:\\30*22=10y\\660=10y\\y=\frac{660}{10}\\y=66[/tex]

So, we get y = 66

Solving the similar triangles, we get x=10.6, y=66
