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

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

Can anyone help me with this question please I really need help please I’ll mark as brainliest

Answer:

$f(x)=-11\times(7^x^-^1)$

Step-by-step explanation:

Stare at the numbers. Especially the first two. First one is -11. Second is $-11\times 7$ . Let's guess you keep multiplying. $-77\times 7=-539$ . Smells correct, let's confirm with the last one: $-539\times7 = -3773$ . I think we found a pattern. Each element is 7 times the previous one. With some practice you can just write the function, else let's divide by -11 away and let's see what we get:

$f(1) = 1=7^0; f(2)=7; f(3)=7^2; f(4)=7^3$ . Basically, the exponent is 1 less than the value we're evaluating the function. That leads tho the following

$f(x)=-11\times(7^x^-^1)$

Answer: Danny can make 15 sundaes from 11 1/4 cups of chocolate

Step-by-step explanation:

number of cups of chocolate syrup= 11 1/4 cups

For ever sundae, he decides to make, it will require 3/4 cup of chocolate

Number of sundae , Danny can make = number of cups of chocolate syrup /3/4 cup of sundae

= 11 1/4 / 3/4

45/4 x 4/3= 15 sundaes

Therefore, Danny can make 15 sundaes from 11 1/4 cups of chocolate
