B = 16

Write an inequality to describe all the points on the coordinate plane above y=-4?
Kipish [7]

Answer: y > -4

Step-by-step explanation: i believe this is your answer because i think you are asking for the range more or less. when you do this, you have to just ask yourself what points would be acceptable (any y point above -4) so the answer would be any y value more than -4, y > -4

Answer:

Im guessing you meant it takes 1/3 cups of flour to make 1/4 of a cake not "14"

Step-by-step explanation:

in that case you would do

1/3+1/3+1/3+1/3

or 1/3*4

which would be 4/3

Find x. (Use pic for more info)
V125BC [204]

Answer:

x=75

Step-by-step explanation:

Hey There!

If you didn't know the exterior angle of a triangle is equal to the sum of the opposite interior angles of a triangle

So essentially what I'm saying is that

2x-5=70+x

step 1 add 5 to each side

-5+5 cancels out

70+5=75

now we have

2x=70+x

step 2 subtract x from each side

x-x cancels out

2x-x=x

we're left with

x=75
