I’m going to answer them for you In English
1: 3x = 15
We divide 3 from both sides
X= 5

2: 2a + 5 = 25
Take the 5 to the other side the sign will be negative 25-5= 20
2a = 20
Divide both sides by 2a
You will get a= 10

Question 8: -7b + 5 = 4b + 13 what is b?
You will collect the like term first
-7b -4b = -5 + 13
-11b = 8
Divide both sides by 11 you get -1.37.

Question 12: x/4 = 5 what is x?

You do cross multiplication the number doesn’t have any denominator it’s always 1
1.x = 1x
4.5= 20

1x= 20
X=20

Hope this helped I didn’t do some of them sorry

Answers

Answer:

B. 60

Step-by-step explanation:

a quadrilateral always adds up to 360°. so you add up all angles then subtract your sum from 360. 140+80=220, now add angle U which is a congruent angle to angle s so 220+80=300. now 360-300=60

Step-by-step explanation:

If 13% is lost by selling goods for Rs 1475, what would be the loss or gain if the goods are sold for Rs 1615?

Answers

Given:

Loss percent is 13%.

Selling price = 1475

To find:

The loss or gain if the goods are sold for Rs.1615?

Solution:

Let x be the cost price of goods.

Loss percent is 13% and selling price is 1475.

[tex]1475=x-\dfrac{13}{100}x[/tex]

[tex]1475=x-0.13x[/tex]

[tex]1475=0.87x[/tex]

[tex]\dfrac{1475}{0.87}=x[/tex]

[tex]1695.4023=x[/tex]

[tex]x\approx 1695.40[/tex]

The cost price of goods is 1695.40.

We need to find the loss or gain if the goods are sold for Rs.1615.

Cost price is greater than the selling price because 1695.40 > 1615. It means , it is a loss.

[tex]Loss=CP-SP[/tex]

[tex]Loss=1695.40-1615[/tex]

[tex]Loss=80.40[/tex]

The loss percent is

[tex]Loss\%=\dfrac{Loss}{C.P}\times 100[/tex]

[tex]Loss\%=\dfrac{80.40}{1695.40}\times 100[/tex]

[tex]Loss\%\approx 4.74\%[/tex]

Therefore, the loss is 80.40 and the loss percent is about 4.74%.

The length of a rectangle is 3 m longer than its width. If the perimeter of the rectangle is 26 m , find its area.

Answers

Answer:

40 m²

Step-by-step explanation:

First, find the perimeter. Using the perimeter formula, p = 2l + 2w, solve for the side lengths of the length and width.

Let w represent the width. The length can be represented by w + 3, since the length is 3 m longer than the width.

Plug in 26 as the perimeter, and plug in w and w + 3 for the width and length:

p = 2l + 2w

26 = 2(w + 3) + 2w

Simplify and solve for w:

26 = 2w + 6 + 2w

26 = 4w + 6

20 = 4w

5 = w

Find the length by adding 3 to this:

5 + 3

= 8

Now, find the area using the area formula, A = lw

Plug in the length and width:

A = lw

A = 8(5)

A = 40

So, the area of the rectangle is 40 m²

Ali and billy ran around a race track. How many more metres did Ali ran than billy in one lap? (Find perimeter)

Answers

Answer:

Ali ran 25.13 m more than bily

Step-by-step explanation:

From the diagram, we can see that bully runs with the inner track line while Ali runs with the outer track line.

Thus;

Diameter of inner semi circle = 20 m

Diameter of outer semi circle = 20 + 4 + 4 = 28 m

Perimeter of inner semi circle = πD/2 = 10π

Perimeter of outer semi circle = πD/2 = 14π

Now, perimeter of Billy = 80 + 80 + 10π + 10π = 222.83 m

Perimeter of Ali = 80 + 80 + 14π + 14π = 247.96 m

Thus, in one lap, difference in distance between Ali and billy = 247.96 - 222.83 = 25.13 m

Write the polynomial in standard form. Then identify the leading coefficient and the constant. Classify the polynomial by the degree and number of terms.
4+5x^(2)-x

Answers

the term is 4x(5^2) gl

Answers:  

Standard Form: 5x^2 - x + 4Leading coefficient:  5Constant: 4Degree:  2Number of terms: 3

=====================================================

Explanation:

The term with the largest exponent will go first, followed by the next largest exponent, and so on. This will get the polynomial into standard form. So 4+5x^2-x turns into 5x^2-x+4. You can think of this as 5x^2-x^1+4x^0. Note the exponents counting down: 2,1,0.

Each term is separated by a plus or a minus. We can think of 5x^2-x+4 as 5x^2+(-x)+4

The leading term is the first term 5x^2. It has the coefficient of 5, so the leading coefficient of the overall polynomial is 5.

The constant is the term without any variables attached to it. So the constant is 4. As the name implies, the constant doesn't change no matter what x changes to. In contrast, the 5x^2 term does change as x changes.

The degree is the largest exponent, so in this case it would be 2. After you get the polynomial into standard form, it's the first exponent on the left.

As mentioned earlier, each term is separated by a plus or a minus. So we have three terms here. We consider this a trinomial since "tri" means "three". More specifically, this is a quadratic trinomial. Any quadratic will have the largest exponent being 2.

Solve each system using substitution. Check your answer
x+3=y
3x+4y=7

Answers

Answer:

x = -5/7

y = 16/7

Step-by-step explanation:

3x + 4y = 7

3x + 4(x+3) = 7

3x + 4(x) + 4(3) = 7

3x + 4x + 12 = 7

7x + 12 = 7

7x + 12 - 12 = 7 - 12

7x = -5

7x ÷ 7 = -5 ÷ 7

x = -5/7

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

x + 3 = y

(-5/7) + 3 = y

16/7 = y

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

3x + 4y = 7

3(-5/7) + 4(16/7) = 7

-15/7 + 64/7 = 7

7 = 7

The required value of the x and y by substitution method is -5/7 and 16/7 respectively.

Given,
System of equation
x+3=y
3x+4y=7

To solve using the substitution method.

What is the equation?

The equation is the values of two functions  that are equal.

What are functions?

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

x + 3 = y - - - - -(1)
3x + 4y = 7 - - - -(2)

from equation 1 substitute y in equation 2

3x + 4( x +3 ) = 7
3x + 4x + 12 = 7
7x = 7 - 12
7x = -5
x = -5/7
put this x on equation 1
-5/7 +3 = y
y = 16/7

Thus the required value of the x and y by substitution is -5/7 and 16/7 respectively.

What is the equation of the line that passes through the point (−7,−1) and has a slope of 11?

Answers

Answer:

          y = 11x + 76

Step-by-step explanation:

The equation of a line with a slope of "a" and containing a given point (x₀, y₀) is:

y - y₀ = a(x - x₀)

a = 11,  x₀ = -7,  y₀ = -1

So:

y - (-1) = 11(x - (-7))  

y = 11x + 77 - 1

y = 11x + 76
