Answer:

-7

Step-by-step explanation:

To find the common difference, take the second term and subtract the first term

-2 - 5 = -7

Check by subtracting the second term from the third term

-9 - (-2) = -9+2 = -7

The common difference is -7

Answer:

The Distributive Property.

Step-by-step explanation:

1.7(x + 9)

= 1.7 * x + 1.7 * 9

= 1.7x + 15.3.

Answer:

x = 7, x = 2

Step-by-step explanation:

Given

x² = 9x - 14 ( subtract 9x - 14 from both sides )

x² - 9x + 14 = 0 ← in standard form

(x - 7)(x - 2) = 0 ← in factored form

Equate each factor to zero and splve for x

x - 7 = 0 ⇒ x = 7

x - 2 = 0 ⇒ x = 2

Answer:

[ (-1,0) (0,0) (1,1) (2,2) (3,3) ]

Domain = { -1,0,1,2,3 }; Range = { 0,1,2,3 }

Step-by-step explanation:

Set or collection of ordered pairs is called 'Relation'. The ordered pairs are in terms f x & y coordinate.

Eg : [ (-1,0) (0,0) (1,1) (2,2) (3,3) ]

Domain is a set of all x axis values. Range is a set of all y axis values. They are arranged non repetitively in ascending order.

Domain = { -1,0,1,2,3 }

Range = { 0,1,2,3 }

As mentioned : the relation has been designed, as such to have five elements in its domain and four elements in its range

Answer: 85

Step-by-step explanation:

To solve this problem, we want to use the order of operations, or PEMDAS.

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

To be more specific, you evaluate the expression in the order from top to bottom. To clarify, it is multiply OR divide, depending on which comes first, left to right. This also applies to add OR subtract.

------------------------------------------------------------------------------------------------------------

20÷(5-3)+5²(3)                              [solve parenthesis]

20÷(2)+5²(3)                                 [solve exponent]

20÷2+25(3)                                   [solve multiply or divide, left to right]

10+75                                             [solve add or subtract]

85

Answer:

85

Step-by-step explanation:

To evaluate the expression, follow the rule of PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

[tex]20 \div (5-3) +5^2(3)[/tex]

Solve inside the parentheses first by subtracting 3 from 5.

5-3 = 2

[tex]20 \div (2) +5^2(3)[/tex]

Next, evaluate the exponent.

5² = 5*5= 25

[tex]20 \div 2+25(3)[/tex]

Next, multiply 25 and 3.

25 *3 =75

[tex]20 \div 2+75[/tex]

Then, divide 20 by 2.

20/2=10

[tex]10+75[/tex]

Finally, add 10 and 75.

[tex]85[/tex]

The expression [tex]20 \div (5-3) +5^2(3)[/tex] evaluated is 85.

Answer:

y=1.5x

Step-by-step explanation:

Step 1: State what you know

Pineapples are 1.50 per pound

X represents how many pounds of pineapples you want to buy

Y represents how much do 'x' amount of pineapples cost in dollars

Step 2: Write the equation

y (the price of 'x' pounds of pineapple)=1.5(the cost of a pineapple)x(how many pounds of pineapples you bought)

Therefore the equation that represents the problem is y=1.5x

Answer:

y=1.5x

Answer:

54 cheese pizzas

Step-by-step explanation:

We know that there are 120 pizzas in the freezer, and 45% of them are cheese pizzas.

We want to find out how many cheese pizzas are in the freezer, so we should multiply 45% and 120.

45% * 120

Convert 45 % to a decimal. Divide 45 by 100 or move the decimal place 2 spots to the left.

45/100= 0.45      or       45.0 --> 4.5 ---> 0.45

0.45 * 120

Multiply 0.45 and 120

54

54 cheese pizzas are in the freezer.

Answer:

$384

Step-by-step explanation:

Original price = $ 400

Increased price  = 20% of 400

                           = [tex]\frac{20}{100}[/tex] * 400

                           = $  80

Price after increase = 400 + 80 = $ 480

Decreased price  = 20% of 480

                             = [tex]\frac{20}{100}\\[/tex] * 480

                            = $ 96

Price after decreasing 20% = 480 - 96 = $ 384

Final price of the toy = $ 384

Each triangle is 40

18*8=144

Each rectangle is 144

144+144+144+40+40=512cm²

Answer:

30

Step-by-step explanation:

2/3 = .6

18/.6 = 30

Answer:

27

Step-by-step explanation:

If you want to divide a fraction, you have to divide it from it's reciprocal.

The reciprocal of 2/3 is 3/2.

Now, you have to multiply 3 and 18

18 x 3/2 = 54/2

54 divided by 2 is 27.

Answer:

[tex]\frac{1}{2}(x+y) - \frac{1}{3}y[/tex]

Step-by-step explanation:

We can translate these words into an expression by just reading them and interpreting them.

Half the sum of x and y.

We know that it's going to include [tex](x+y)[/tex], and if we're taking half of that, we multiply that by [tex]\frac{1}{2}[/tex], so [tex]\frac{1}{2}(x+y)[/tex]

We also know that one third of y will be multiplying y by [tex]\frac{1}{3}[/tex], so [tex]\frac{1}{3}y[/tex].

Since we are decreasing [tex]\frac{1}{2}(x+y)[/tex] by  [tex]\frac{1}{3}y[/tex], there's a minus sign between the terms.

So, [tex]\frac{1}{2}(x+y) - \frac{1}{3}y[/tex].

Answer:

[tex]\Huge \boxed{\mathrm{12.67 \ s}}[/tex]

Step-by-step explanation:

[tex]\displaystyle power \ (W) = \frac{work \ done \ (J)}{time \ (s)}[/tex]

[tex]\displaystyle P= \frac{W}{t}[/tex]

[tex]\displaystyle 15= \frac{190}{t}[/tex]

Solve for t.

Multiply both sides by t.

[tex]15t =190[/tex]

Divide both sides by 15.

[tex]\displaystyle t= \frac{190}{15}[/tex]

[tex]t \approx 12.67[/tex]

[tex] \bf \underline{ \underline{given : }}[/tex]

[tex]\bf \underline{ \underline{To \: be \: calculated : }}[/tex]

Calculate the time ?

[tex]\bf \underline{ \underline{

Formula \: applied :}}[/tex]

[tex] \boxed{ \bf{Power = \frac{Work \: done}{Time} }}[/tex]

[tex]\bf \underline{ \underline{Solution : }}[/tex]

We know,

[tex]\sf {Power = \dfrac{Work \: done}{Time}}[/tex]

[tex] \sf{ Time = \dfrac{Work \: done}{Power } }[/tex]

Substituting the values of work and power, we get:

[tex] \sf \implies{Time = \dfrac{190}{15} }[/tex]

[tex] \sf\implies{Time = 12.66 \: s}[/tex]

Thus,the time taken by a body is 12.66 seconds.

Answer:

first of all i need to know the fractions and answer choices to answer this question.

Answer:

0

Step-by-step explanation:

So we have the equation:

[tex]3(x+14)=42[/tex]

Divide both sides by 3:

[tex]x+14=14[/tex]

Subtract 14:

[tex]x=0[/tex]

The value of x is 0

Answer: x=0

Step-by-step explanation:

Given

3(x+14)=42

Distributive property

3x+42=42

Subtract 42 from both sides

3x=0

Divide 3 on both sides

x=0

----------------------------------------------------

Given

3(x+14)=42

Divide 3 on both sides

x+14=14

Subtract 14 on both sides

x=0

Both ways are fine

Answer:

Rs. (x - y + 2)

Step-by-step explanation:

The marked price is the price that a product is to be sold. The product can be sold at a discount which is below the marked price of the product.

The marked price of the article is Rs. X. The discount is Rs. y, therefore the article price = marked price - discount = x - y.

But since the article is sold with a VAT of Rs. 2, the VAT is added to the price, therefore the selling price of the article including VAT is Rs. (x - y + 2)
