Answer:

The correct answer is option B.

x = 10 and y = 46

Step-by-step explanation:

From the figure we can see a trapezium.

<u>To find the value of x</u>

We can write,

2x - 13 = x - 3

2x - x = 13 - 3

x = 10

<u>To find the value of y</u>

from the figure we can write,

3y - 4 + y = 180

4y = 180 + 4

4y = 184

y = 184/4 = 46

Therefore the correct answer is option B

x = 10 and y = 46

Seven-tenths of the product of 5p and 3 in algebraic expression
maw [93]

Answer:

\frac{7}{10}(5p*3)

Step-by-step explanation:

we know that

The algebraic expression of seven-tenths is equal to the number 7 divided by ten

\frac{7}{10}

The algebraic expression of the product of 5p and 3  is equal to multiply 5p by 3

(5p*3)

therefore

The algebraic expression of seven-tenths of the product of 5p and 3 is equal to

\frac{7}{10}(5p*3)

pentagon [3]

Answer:

\large\boxed{y=-\dfrac{1}{2}x+b,\ \text{wher}\ b\in\mathbb{R}.}

Step-by-step explanation:

\text{Let}\ k:y=m_1x+b_1,\ l:y=m_2x+b_2\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\\\l\ \parallel\ k\iff m_1=m_2\\==========================\\\\\text{The slope-intercept form of an equation of a line:}\\\\y=mx+b\\\\m-slope\\b-y-intercept\\==========================\\\\\text{We have the equation of the line:}\ y=2x+17\to m_1=2.\\\\\text{Therefore}\ m_2=-\dfrac{1}{2}.\\\\\text{The equation of a line:}\ y=-\dfrac{1}{2}x+b,\ \text{wher}\ b\in\mathbb{R}.

at a clothing store, levi's jeans are on sale for 40% off. sales tax is 7%. which expression will calculate the total cost of le
aleksandrvk [35]

Given:

Discount = 40%

Sales tax = 7%

To find:

The total cost of levi jeans with an original price of x.

Solution:

Let x be the original price of the jeans. Then the price after 40% discount is

Price=x-40\%\text{ of }x

Price=x-\dfrac{40}{100}x

Price=x-0.4x

Price=0.6x

The price after 7% of sales tax.

Price=0.6x+7\%\text{ of }0.6x

Price=0.6x+\dfrac{7}{100}\times 0.6x

Price=0.6x+0.042x

Price=0.642x

Therefore, the total cost  of the levi jeans with an original price of x is represented by the expression 0.642x.

I WILL GIVE BRAINLIEST!! :D
STALIN [3.7K]

Answer:

The number in the middle is 60.

Step-by-step explanation:

The 2nd number = A

The 3rd number = B

The 4th number = C

Given:

(1) 130 + A + B = 300

(2) A + B + C = 200

(3) B + C + 10 = 100

Now, the work:

(2) can be modified to become A + B = 200 - C

Now, we can insert that into (1) and get the following;

130 + (200 - C) = 300

Open parentheses, simplify, you get C = 330 - 300.

C = 30

Using (3), we use above answer to get B + 30 + 10 = 100

Calculate, and get B = 100 - (30 + 10)

Simplify,

B = 60

There is your answer!

Cheers
