Answer:

3): 14

Step-by-step explanation:

The problem states that ABC and DEF are similar. Therefore, dsue to similar triangles, we have 7x/7=4/x, so x^2=4. Therefore, x=2 (because x cannot be negative). Therefore, AB = 7x = 7*2=14

Glenda has some sweets. If she gives each of her friends 6 sweets, there will
Grace [21]

Answer:

Number of sweets =54

Step-by-step explanation:

Let number of friends  = x

Number of sweets  = y

Glenda gives 6 to each of her friend,

6x = y  ----------------(I)

If she gives each of them 4, 18 is left

4x + 18 = y ---------------(II)

From (I)& (II)

6x = 4x + 18

Subtract 4x from both sides

6x - 4x = 4x + 18 - 4x

2x = 18

Divide both sides by 2

2x/2 = 18/2

x = 9

y = 6x

  = 6 * 9

y = 54

Number of sweets =54

20 yards 8 inches is divided into 26 equal sections, how long is each section
hoa [83]
In the given question, there are several information's of immense importance and worth taking a look. based on these information's, the answer to the question can be easily determined.The length that has to be divided into 26 equal parts is 20 yards and 8 inches.Firstly we have to change the yard into inches and then we can divide the total inches into 26 equal parts.
We know
1 yard = 36 inches
20 yards = 720 inches
Then the total length that has to be divided = (720 + 8) inches
                                                                     = 728 inches
Now we have to divide the 728 inches into 26 equal parts.
Length of each section = (728/26) inches
                                      = 28 inches.
So each of the 26 parts will have a length of 28 inches.

Why math even exist people could just like wing it for everything
s2008m [1.1K]

Answer:

- 7 / 4

Step-by-step explanation:

( x1, y1 ) = ( 1, 10 )

Here,

x1 = 1

y1 = 10

( x2, y2 ) = ( 5, 3 )

Here,

x2 = 5

y2 = 3

Formula : -

Slope = ( y2 - y1 ) / ( x2 - x1 )

Slope = ( 3 - 10 ) / ( 5 - 1 )

Slope = - 7 / 4

Proper fraction = - 7 / 4
