Answer:

converting the equation to improper fraction

31/5+(-38/5)

31/5-38/5( the plus sign affected the minus sign inside of the bracket which is+*- = -)

multiply both terms by 5

5−4+7+1= 5 - 4 + 7 x + 1 = how is it no solution

laila [671]

Answer:

There is a solution. Here's how:

Step-by-step explanation:

So, you work out the problem, and you lay it out here:

5-4+7+1=5-4+7x+1.

First, you start by subtracting 5 from both sides, which cancels both of the 5s. Here's your equation now:

-4+7+1=-4+7x+1

Next, you add 4 to both sides, which makes you identify the identity.

Here's your equation now:

7+1=7x+1

Now, you subtract 1 from both sides.

Here's your equation now:

7=7x

Finally, divide both sides by 7, while identifying the identity.

x=1.

EF is the median of trapezoid ABCD.

BARSIC [14]

Answer:

Part A) $x = 11$

B) length of BC = x + 12 = x + 12 = 11 + 12 =23

length of EF = 4x - 18 = 4(11) - 18 = 44 - 18 =26

length of AD = 3x - 18 = 3(11) - 4 = 33 - 4 =29

Step-by-step explanation:

Median of trapezium is $m=\frac{base1+base2}{2}$

In provided figure, base1 is x+12 and base2 is 3x-4

A) solve for value of x

calculate the median $m=\frac{base1+base2}{2}$

$4x-18=\frac{x+12+3x-4}{2}$

$4x-18=\frac{4x+8}{2}$

$4x-18=2x+4$

$2x-18=4$

$2x = 18 + 4$

$2x = 22$

$x = 11$

B) To find the length of BC, AD and EF , put the value of x in equation of lines

length of BC = x + 12 = x + 12 = 11 + 12 =23

length of EF = 4x - 18 = 4(11) - 18 = 44 - 18 =26

length of AD = 3x - 4 = 3(11) - 4 = 33 - 4 =29
