Answer:

x = - 3.75

y = 28.75

Step-by-step explanation:

[tex] \begin{cases} x + y = 25\\\\ 5x + y = 10 \end{cases} [/tex]

Since, x + y = 25

Therefore, y = 25 - x..... (1)

5x + y = 10......(2)

Plug y = 25 - x in equation (2), we find:

5x + 25 - x = 10

5x - x = 10 - 25

4x = - 15

x = - 15/4

x = - 3.75

Plug x = - 3.75 in equation (1), we find:

y = 25 - (- 3.75)

y = 25 + 3.75

y = 28.75

(x, y) = (-3.75, 28.75)

Answer:

1. equation

2. inequality

3. inequality

Step-by-step explanation:

Answer:

B: Using x and y factor results in an expression of greater value than using x and y as terms.

Step-by-step explanation:

For her first expression, x and y are factors;

xy

For her second expression, x and y are written as terms;

x + y

For x and y are both negative integers, then;

-x * -y = xy  ............... 1

-x + (-y) = - x - y

            = - (x + y)  .............. 2

Therefore, the value of x and y factors is greater than that when x and y are as terms. Thus the correct option is B.

Answer:

868.3%

Step-by-step explanation:

8.683 x 100 =  868.3%

Answer: 868.3%

All you need to do to convert a decimal to a percentage is multiply by 100. In this case we have to multiply 8.683 by 100 which gives us 868.3%

Answer:

See Explanation

Step-by-step explanation:

This question requires further details. In absence of the details, I will answer on a general term.

When a line is dilated (whether expanded or compressed), the new line will be on the same line with the dilated line; however, the length of both lines will be different

Take for instance:

Line AB of coordinate (1,3) is horizontally dilated by 2,

Horizontal dilation rule is: y = f(cx) where c is the dilation factor

So, the new point will be

A'B' = (1, 3 * 2)

A'B' = (1,6)

When you compare the x coordinate of both line, you will observe that they have the same x coordinate of 1.

This implies that they are on the same level but different length

The same is applicable to vertical dilation

the new point will be:

Answer: k = 27

Step-by-step explanation:

Here's the complete question:

Write the word sentence as an equation. Then solve the equation. A number k increased by 7 is 34.

An increase in k simply means that there's an addition. This will be:

k + 7 = 34

k = 34 - 7

k = 27

Therefore, the value of k is 27

Answer:

7x + 8y = 16

Step-by-step explanation:

You need to get the slope of the given line.  

The line is in standard form ax + by = c

The slope = -a/b.  (That's a little formula you can use to find the slope when the line is in standard form)

In this problem,  m = - 7/8

Since the line we are trying to find is parallel, it has a slope of -7/8

Now use the point-slope form

y - (-12) = -7/8(x - 16)    Multiply thru by 8 to remove the fractions

8(y + 12) = -7(x - 16)

8y + 96 = - 7x + 112

7x + 8y = 16

Answer:

A.2 Hours.

B.2 Inches.

Step-by-step explanation:

Its easy,

A. 8 inches = 4 hours, 4 inches = .... hours

4 inches = 8 ÷ 2

Hours: 4 hours ÷ 2 = 2 hours

B. 8 inches = 4 hours, .... inches = 1 hour

1 hour = 4 ÷ 4

Inches: 8 inches ÷ 4 = 2 inches.

Step-by-step explanation:

Given data

Cost of dinner= $32

TIp=18%

Let us find the amount of the tip

=18/100*32

=0.18*32

=$5.76

Hence the total amount paid is

=5.76+32

=$37.76

The Tip is

=$5.76

Answer:

35

Step-by-step explanation:

Since you know that a triangle must have a total of 180 degrees and a right triangle is 90 degrees then you just subtract 90 from 180 and you get 90. Then subtract 55 from 90 and you get 35 which is the only possible answer.

Answer:

It is the first answer choice

Answer:

$35

Step-by-step explanation:

Find the cost of 1 apple

$25/50 = 0.5

1 apple costs 50 cents/ 0.5 dollar

Multiply by 70 to find the cost of 70 apples

$0.5 x 70 apples = 35

$37.50. ...................

Answer:

B

Step-by-step explanation:

The function's zeroes results in vertical asymptotes. As one is at x = 1 and the other at x = -2, the zeroes must be (x-1) and (x+2), which only B contains in the numerator.

Answer:

  64 -16π square units

Step-by-step explanation:

The area of the square is ...

  A = (8 units)^2 = 64 units^2

The area of the circle is ...

  A = πr^2 = π(4 units)^2 = 16π units^2

The shaded area is the difference:

  shaded area = (64 -16π) units^2.

Answer:

84 tiles

Step-by-step explanation:

Given that :

Figure 2 = 8 tiles

Figure 5 = 14 tiles

Growth rate :

(Figure 5 - figure 2)x= 14 - 8

3x = 6

x = 6/3

x = 2

(Figure 40 - figure 2) = 38 * x

Initial number of tiles + 38x

8 + 38(2)

8 + 76

= 84

Figure 40 = 84 tiles

Answer:

a) 40 inches

b) No it will not fit inside

Step-by-step explanation:

Angharad is buying a new 50-inch screen TV (remember that TV screens are measured along the diagonal )

a) If it is 30 inches tall, how wide is the screen ?

Diagonal ² = Width² + Height²

Diagonal = 50 inches

Height = 30 inches

50² = Width² + 30²

Width² = 50² - 30²

Width = √50² - 30²

Width = √(1600)

Width = 40 inches

b) Her TV cabinet is 30 inches wide .will the TV fit inside it ?

No it will not fit inside

This is because, the width of the TV is the above calculation is 40 inches. This is wider than the width of the TV cabinet, hence, it won't fit inside
