Answer 1

Answer:

x=38

y=24

Step-by-step explanation:

Answer 2

Answer: x = 15, y = 6

Step-by-step explanation:

1). (7y - 1) + (9x + 4) = 180 (the are supplementary angles)

2). (4x-7) + (7y - 1) + 86 = 180 (sum of angles in a triangle)

7y - 1 + 9x + 4 = 180

7y + 9x + 3 = 180

9x + 7y = 177

4x - 7 + 7y - 1 + 86 = 180

4x + 7y - 8 + 86 = 180

4x + 7y + 78 = 180

4x + 7y = 102

Now solve the system of equations

subtract the two equations

9x + 7y = 177

-(4x + 7y) = -(102)

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

5x = 75

x = 15

Substitute the value of x into either equation to find y

4(15) + 7y = 102

60 + 7y = 102

7y = 42

y = 6

if SP =210 profit percent =5% CP = X , find CP​

Answers

Step-by-step explanation:

Given

SP = 210

profit percent (p%) = 5%

CP = X = ?

We know

Cost price (CP)

[tex] = \frac{sp \: \times 100}{100 + p\%} \\ = \frac{210 \times 100}{100 + 5} \\ = \frac{21000}{105} \\ = 200[/tex]

hope it helps :)❤

Or in another way

Let the cost price be x then

Profit amount

= 5 % of CP

= 5/100 * x

= x / 20

Selling Price (SP)

210 = CP + Profit amount

210 = x + x / 20

210 = ( 20x + x) / 20

210 * 20 = 21x

4200 = 21x

x = 4200 / 21

x = 200

Therefore CP = 200

Answers

Answer:

d = 105tan(37°)

Step-by-step explanation:

opposite (o) = d

adjacent (a) = 105

Angle A = 90 - 53 = 37°

Therefore,

the correct equation would be

tan(A°) = opposite/adjacent

tan(37°) = d/105

d = 105tan(37°) ✅

d = 105 × 0.7535540501

d ≈ 79.12 units

What is the equation of the line that passes through (3.-5) and is parallel to 5x - 3y = 15?​

Answers

Answer:

y = 5/3x - 10

Step-by-step explanation:

[tex]5x - 3y = 15\\-3y = -5x + 15\\y = 5/3x - 5[/tex]

that means the slope of the new line also has to be 5/3 because parallel lines have the same slope.

put it in point-slope form:

y - -5 = 5/3(x - 3)

y + 5 = 5/3x - 5

y = 5/3x - 10

Answers

Answer:

33+12t−21t^2

Step-by-step explanation:

(2t-7)²-(5t-4)²

Use binomial theorem (a−b)^2 = a^2−2ab+b^2 to expand (2t-7)².

4t^2−28t+49−(5t-4)²

Use binomial theorem (a−b)^2 = a^2−2ab+b^2 to expand (5t-4)².

4t^2−28t+49−(25t^2−40t+16)

To find the opposite of 25t^2

−40t+16, find the opposite of each term.

4t^2−28t+49−25t^2−40t+16

Combine 4t^2  and −25t^2  to get −21t^2.

−21t^2−28t+49+40t−16

Combine −28t and 40t to get 12t.

−21t^2+12t+49−16

Subtract 16 from 49 to get 33.

−21t^2+12t+33

Swap terms to the left side.

33+12t−21t^2

solve the following
a brick measures
l= 15 cm
b= 8 cm
h= 5 cm
how many bricks will be used to make a wall of length=15 m, breath=10 m and height=8m

Answers

Answer:

2000000 bricks

Step-by-step explanation:

The computation of the number of bricks to be used is shown below:

The Volume of brick is

= (15 × 8 × 5)cm^3

= 600 cm^3

And, the Volume of wall is

= (1500 × 1000 × 800)cm^3

= 1200000000 cm^3

Now Bricks needed is

= 1200000000 cm^3 ÷ 600cm^3

= 2000000 bricks
