Solve: x=4+(4x-4)1/2 x = 2
Andreyy89

Answer:

No real solution- Not any of the options anyway

Step-by-step explanation:

So I replaced the x's with the two possible equations and then tried to solve...

2=4+(4x2-4)1/2

2=4+(8-4)1/2

2=4+(4)1/2

2=8(1/2)

2=4   Which is not true

10=4+(4x10-4)1/2

10=4+(40-4)1/2

10=4+36(1/2)

10=40(1/2)

10=20 Which is also not true

Therefore, there is no real solution

Two angles of a triangle measure 22 and 53 what is the measure of the third angle
Musya8 [376]
The third angle is 105.
How do I know this?
Add 22 and 53:
22 + 53 = 75
All interior angles on a triangle should add up to 180.
Subtract 75 from 180:
180 - 75 = 105
105 is our answer.
Hope this helps! =)

photoshop1234 [79]

Answer:

hello your question has some missing parts attached below is the missing information

answer : Scott will make 5 snack mix without going over

Step-by-step explanation:

Given that:

Scott makes a snack  mix with ; 2 cups of Almonds and 3 cups of raisins

=  5cups per snacks mix

Ariel makes a snack mix with : 3 cups of almonds and 5 cups of sunflower seeds = 8 cups per snack mix

<u>Now back to your question above</u>

Given that : No more than 25  full cups is required to make a snack mix

For Scott

= 25 / 5 = 5 snack mix ( No make overs )

For Ariel

= 25 / 8 = 3.125 snack mix ( there is a makeover of 0.125 )

Hence it can be said that Scott will make the most mix without going over
