Answer:

65%

Step-by-step explanation:

Given data

Cost price= £4000

Selling price=  £1400

% loss= cost price-selling price/cost*100

% loss= 4000-1400/4000*100

% loss= 2600/4000*100

% loss= 0.65*100

% loss= 65%

Hence the %loss is 65%

Answer:

b and D

Step-by-step explanation:

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.

The expression that is equivalent to 32x - 48 are,

-4(-8x - 12)

4(8x - 12)

8(4x - 6)

Options A, B, and D are the correct answers.

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,

32x - 48

A.

-4 (-8x - 12)

= (-4 x - (8x)) - (-4 x -12)

= 32x - 48

B.

4 (8x - 12)

= 32x - 48

C.

8(-4x + 6)

-32x + 48

D.

8 (4x - 6)

32x - 48

Thus,

The expression that is equivalent to 32x - 48 are,

-4(-8x - 12)

4(8x - 12)

8(4x - 6)

Options A, B, and D are the correct answers.

Answer: x=20

Step-by-step explanation: 2(20)=40 40-10=30

Answer:

4

Step-by-step explanation:

3/4(x+8)=9

3/4x+6=9

3/4x=3

x=4

P.S. PLEASE give me Brainliest!

Answer: x = 4

Step-by-step explanation:

Divide both sides by 3/4. When you divide by a fraction, you can also multiply by the reciprocal

[tex]x+8=9*\frac{4}{3}[/tex]

Simplify the fraction

[tex]x+8=\frac{36}{3} \\x+8=12\\[/tex]

Subtract 8 on both sides

x = 4

..........the answer is 48 × 10^-8

Answer: 50.2ft

Step-by-step explanation:

I used tangent to find the length of the base of the triangle.

Tan = opposite / adjacent and I solved for opposite getting 50.2.

PS I literally swore to myself I wouldn’t bring out pen and paper and get into trig tonight over this app but since you asked I did. I’m pretty confident in my answer but just know, I last took math four years ago.

Step-by-step explanation:

Let's simplify step-by-step.

4x−6−(5x+1)

Distribute the Negative Sign:

=4x−6+−1(5x+1)

=4x+−6+−1(5x)+(−1)(1)

Answer:

x = 2, y = -3

or

(2, -3)

Step-by-step explanation:

6x + 2y = 6

7x + 3y = 5

multiply the first equation by -3 and the second equation by 2 and solve by elimination

6x + 2y = 6

becomes

-18 - 6y = -18

7x + 3y = 5

becomes

14x + 6y = 10

then, add the new equations.

-18x - 6y = -18

14x + 6y = 10

-4x + 0 = -8

-4x = -8

4x = 8

x = 2

then, substitute x for 2 in one of the eqautions.

6x + 2y = 6

12 + 2y = 6

2y = 6 - 12

2y = -6

y = -3

The formula for finding the area of a parallelogram is Base x height

A = Bh

In this case the base (the longest side) is 8 cm and the height (distance between the obtuse angle and the base) is 5 cm

A = 8 * 5

A = 40 cm²

Hope this helps!

~Just a girl in love with Shawn Mendes

Answer: 40cm²

The formula is Base × Height. We can find the area if we multiply the Base and Height.

A = Bh

As for that, the Base is the upper length, which is 8 and the height is the obtuse angle inside the parallelogram, which is 5.

Since we got our lengths, we can solve.

Remember how I said the formula is A = Bh. (Area = Base × Height)

So, we can multiply 8 by 5 to get the area.

8 times 5 will equal 40.

Hence, 40cm² is the answer.

Answer:

the slope is: Positive

slope is: 1/5

y-intercept: -4

equation is: y = 1/5x - 4

Answer:

Slope: Postive

Slope: 5

Y-Intercept: -4

Equation: y = 5x - 4

Step-by-step explanation:

A positive slope rises left to right, a negative slope rises right to left.

The slope is [tex]\frac{rise}{run}[/tex].

The y-intercept is where the line meets the y-axis.

The equation is written in the form y = mx + b, where m is the slope and b is the y-intercept.

2/5

Step-by-step explanation:

cause if you put it in a percent it would be 40% so bigger than 35%

Answer:

2/5 is bigger than 35%

Step-by-step explanation:

2/5 can be written as 4/10, which is equivalent to 40/100, or the percentage 40%. And since 40% is bigger than 35%, 2/5 is bigger than 35% :)
