Answer:

-7-(-4)= -3

Step-by-step explanation:

Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive.

Answer:

Step 1: 1,000, Step 2: 1,000, Step 3: 30,000

Step-by-step explanation:

For the first step all you have to do is find out what times 5 is equal to 5000.

[tex]5*x=5000\\[/tex]

Then for the second one all you have to do is keep the same 1000, because:

[tex](5*6)*1000=30*1000[/tex]

It's the same thing.

Afterwards you can just assume that you'll have 30000 as your answer because multiply 30 by 1000 will give, 30 thousands.

[tex]30*100=30000[/tex]

Inequality is the opposite of equality and it is shown here in the line starting from -2 ends in a number of a value other than of -2 but 8 so it is inequality

Answer:

a) 2*a*b - a/b

b)  c² + d + 2*c*d

c)  c + c²

d) (1 + b)/(2*b)

e)  p*q - 3*(p+q)

f) n²/(n+5)³

Step-by-step explanation:

We can divide each statement into its parts, as follows:

a) The difference between:

b) The sum of:

c) The sum of:

d) The quotient of:

e)

f) The quotient of:

All the algebraic expressions are written as,

a) 2ab - (a/b)

b) c² + d + 2cd

c)  c + c²

d) (1 + b)/(2b)

e)  pq - 3(p+q)

f) n²/(n+5)³

Used the method of a mathematical expression,

Mathematical expression is defined as the collection of numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now, simplify all the expressions for mathematical form as,

a) The difference between twice the product of a and b and the quotient of these numbers.

Here, twice the product of a and b is,

2 × (ab)

And, the quotient of these numbers is,

a/b

Hence, it can be written as,

[tex]2ab - \dfrac{a}{b}[/tex]

b) The sum of squares of c and d increased by twice their product.

Here, d increased by twice their product is,

d + 2cd

And, The sum of squares of c and d increased by twice their product is,

c² + (d + 2cd)

c) The sum of a number c and its square is,

c + c²

d) Now, the number that is 1 greater than a number b is,

1 + b

And the number that is twice as large as b,

2b

So, The quotient of the numbers,

(1 + b)./2b

e) Now, The product of two numbers, p, and q is,

p × q

And, it is decreased by three times their sum:

p × q - 3 (p+q)

pq - 3 (p + q)

f) Now, the square of a number n is, n²

and the cube of n increased by 5 is, (n+5)³

So, The quotient is,

n² / (n + 5)³

Answer:

20

Step-by-step explanation:

Because this is a right triangle, you can use the Pythagorean Theorem, a^2 + b^2 = c^2.  a and b are your legs and c is your hypotenuse, so you have 21^2 + b^2 = 29^2. This equals to 441 + b^2 = 841. subtract 441 from both sides and you are left with b^2 = 400. take the square root of both sides to get your answer b = 20, or x = 20.

Answer:

x = 20

Step-by-step explanation:

→You can use the Pythagorean Theorem to solve this:

[tex]a^2 +b^2=c^2[/tex]

→The "a," and "b," are the legs, 21 and x, while the "c," is the hypotenuse, 29. In this case, we are trying to find the value of a leg:

[tex]21^2+b^2=29^2[/tex]

[tex]441+b^2=841[/tex]

→Subtract 441 from both sides:

[tex]b^2=400[/tex]

→To get "b," by itself, you must take the square root of both sides, like so:

[tex]\sqrt{b^2} =\sqrt{400}[/tex]

[tex]b = 20[/tex]

Answer:

5.627

Step-by-step explanation:

[tex]5 \times 1 + 6 \times \bigg( \frac{1}{10} \bigg) + 2 \times \bigg( \frac{1}{100} \bigg) + 7\times \bigg( \frac{1}{1000} \bigg) \\ \\ = 5 + 0.6 + 0.02 + 0.007 \\ \\ = 5.627[/tex]

ANSWER:

1.9

EXPLANATION:

Volume of a pyramid = V= lwh/3

V= Volume

L= Length

W= Width

to get length we divide 5 by 4 which is 1.25

therefore V= 1.25×1.25×3.6/3

V= 1.89

1.89 to the nearest tenth is 1.9

Answer:

B. (-9/2, -11/2)

Step-by-step explanation:

-12+3 / 2 = -9/2

-3+-8 / 2 = -11/2

Step-by-step explanation:

4x² + 11x - 3 = 0

(4x-1)(x+3) = 0

x = 1/4, -3

Answer:

x = -3 or x = 1/4

Step-by-step explanation:

Please see the graph in the attachment.

4 x^2 + 11 x - 3= 0

4 (x + 3) (x - (1/4)) = 0

(x + 3)= 0 or (x - (1/4))= 0

x = -3 or x = 1/4

Answer: 4096

Hope this helps.

Answer:

Step-by-step explanation:

Let yesterday's price  be x

Discount percentage = 36%

Sale price = $ 560

(100-36)% of x = 560

64 % *x = 560

[tex]\frac{64}{100}*x=560\\\\x=560*\frac{100}{64}\\\\x=875[/tex]

Yesterday's price = $ 875

Answer:

A : (-2) + (3)i

B : (-1) + (1)i

C : (3) + (-4)i

D : (4) + (1)i

Step-by-step explanation:

In the graph attached,

Real part of a complex number is plotted on x-axis and imaginary part of the complex number on y-axis.

x → Real part of the complex number

y → Imaginary part of the complex number

Complex numbers are,

A : (-2) + (3)i

B : (-1) + (1)i

C : (3) + (-4)i

D : (4) + (1)i

Answer:

A : (-2) + (3)i

Answer: i say B is correct

Answer:

B  -->  y is 1/3 of x

Step-by-step explanation:

x:y is 3:1

=>  x is bigger than y

=>  x is 3x bigger than y

=>  x = 3 lots of y

=>  [tex]x = 3y[/tex]

=>  [tex]\frac{x}{3} = y[/tex]

=>  [tex]\frac{1}{3} x = y[/tex]

Therefore y is [tex]\frac{1}{3}[/tex] of x

This means that B is correct

Answer:

The triangles are Similar Triangles

Step-by-step explanation:

The corresponding angle are NOT proportional

The ratios of corresponding sides ARE equal.

The corresponding sides are NOT congruent.

The corresponding angle HAVE same measure

Two triangles are said to be similar triangle when they have the same shape but not necessarily the same size.

Which means that if two triangle have there corresponding angles congruent, and if there corresponding sides are in ratio, they are considered as Similar Triangle.

Corresponding angle:

∠H = ∠E

∠G = ∠F

∠I = ∠D

All angle are congruent

Ratio of Corresponding sides:

16/3.2 : 15/3 : 10/2

5:5:5

Hence Proved

Question: What can be concluded about these triangles? Check all that apply. Answer:  B,D,and E.
