If EF - 3x - 11, FG = 4x-10, and EG - 28, find the values of x, EF, and FG. The drawing is not to scale.

Gnom [1K]

Answer:

Part 1) $x=7$

Part 2) $EF=10\ units$

Part 3) $FG=18\ units$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the value of x

we know that

$EG=EF+FG$ ---> by addition segment postulate

we have

$EG=28\ units\\EF=3x-11\\FG=4x-10$

substitute

$28=(3x-11)+(4x-10)$

solve for x

$28=7x-21$

$7x=28+21$

$7x=491$

$x=7$

step 2

Find the value of EF

$EF=(3x-11)$

substitute the value of x

$EF=3(7)-11=10\ units$

step 3

Find the value of FG

$FG=(4x-10)$

substitute the value of x

$FG=4(7)-10=18\ units$

Had 24 beads he divided them into four equal groups and gave one group to his sister how many beads did Lawrence have then

const2013 [10]

Answer:

If Lawrence has 24 beads and divided them into 4 groups you want to see how many he put into each group first

To do this we are going to take 24/4=6

Each group has 6 in it

If he gave one group to his sister, than he gave 6 beads to his sister

Now we want to take 6 away from 24 to find out how many he has left

24-6=18

He now has 18 beads

Hope this helps ;)
