Answer:

x = 7

Step-by-step explanation:

The difference between the length and width is 3 , then length = x - 3

area (A) of rectangle = length × width

A = x(x - 3) = 28 , distribute parenthesis

x² - 3x = 28 ( subtract 28 from both sides )

x² - 3x - 28 = 0 ← in standard form

(x - 7)(x + 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

x + 4 = 0 ⇒ x = - 4

However, x > 0 , then x = 7

Answer:

A is the answer.

Answer:

7/50

Step-by-step explanation:

Here is an easy way of converting a decimal number to fraction.

Step 1:

Write it down as 0.14/1

Step 2:

Multiply bottom and top by 10 for every number after the decimal, since there is 2 numbers after the decimal you do 10*10 = 100

[tex]\frac{0.14(100)}{1(100)}[/tex] = 14/100

Step 3:

You can simplify 14/100 to 7/50 and thats why 7/50 is the answer

Answer:

[tex]\frac{14}{100}[/tex] or [tex]\frac{7}{50}[/tex]

Step-by-step explanation:

To find 0.14 we have to see what place it's in, since it was in the hundredths place, we put 14 over 100, which is 14/100.

To simplify this fraction we have to find the GCM (Greatest Common Factor), the GCM of 14 and 100 is 2. Then we divide both the bottom and the top by 2 (whatever you do to the bottom, you do to the top), which gives us 7/50.

To conclude, 0.14 as a fraction is 14/100 or 7/50.

Answer:

5:1

Step-by-step explanation:

5/6 won

1/6 lost

5:1=6

Answer:

5:1

Step-by-step explanation:

Total numbers of match = 6

No. of matches Peter wins = 5

Ratio of wins to lose = 5:(6-5) = 5:1

Please, don't write the answer as 1:5. Because, 5:1 and !:5 both are different so don't be confused.

coz I used the table method so I also found it's correct

Answer:

y = 5(4ˣ)

Step-by-step explanation:

Answer:

y = 5 * 4^x

Step-by-step explanation:

exponential functions are of the form

y = ab^x

to find a use point (0, 5)

5 = ab^0

5 = a * 1

a = 5

To find b use any other point

using (1, 20)

20 = 5(b^1)

4 = b^1

b = 4

The equation is

y = 5 * 4^x

Answer:

3/4 bags of trail mix

Step-by-step explanation:

She ate 1/2 of a bag, she gave 1/3 of a bag, and she dropped 1/6 of a bag. In total she "lost" 1/2+1/3+1/6=1 bag of trail mix. So she has 1 3/4-1=3/4 bags left

D. Multiply both sides by -7

Step-by-step explanation:

So solving would look like this

m/-7 < 14

m > -2

Remember when multiplying by a negative the sign flips, hope that helps :)

Answer:

It is either 4 or 9.

Step-by-step explanation:

because you have to subtract or divide

Answer:

use these formulas to solve

Step-by-step explanation:

Principal( P) = interest / rate x time

Rate (R) = intrest / principal x time

Intrest (I) = PRT

Answer:

8

Step-by-step explanation:

4+4 =8

Answer:

y = 8

Step-by-step explanation:

To find this simply you have to put values instead of x and y,

For an example,

If the value of x is 1, you have to put 1 instead of x to the equation to find the value of y,

x = 1,

y = x + 4

y = 1 + 4

y =  5

In the same way, you can find the value of y when the value of x is 4.

x = 4,

y = x + 4

y = 4 + 4

y = 8

Hope this helps you.

Let me know if you have any other questions :-)

Answer:

The larger number is 67 and the smaller number is 13

Step-by-step explanation:

y=5x+2

x+y=80

-5x+y=2

6x=78

x=13

y=65+2

y=67

So, the question is 63 is 30% of what number?

That can translate to the equation

     63 = 30% · x     or     63 = 0.3x

Divide by 0.3 and you get x = 210.

Answer:

  -3, 1

Step-by-step explanation:

The vertical scale of the graph is f(x). So, f(x) = 0 is the x-axis. Where the graph crosses the x-axis, the value of f(x) is 0.

The x-axis is labeled on alternate lines. Those labels are sufficient to tell you that each grid line represents one unit. The curve intersects the x-axis 3 units to the left of the vertical axis, at x = -3, at 1 unit to the right of the vertical axis, at x = 1.

The values of x where f(x) = 0 are -3 and 1.
