Answer:
x > 15
Step-by-step explanation:
simplify both sides of the inequality
2x + 9 > 39
subtract 9 from both sides
2x + 9 - 9 > 39 -9
2x > 30
divide both sides by 2
2x/2 > 30/2
x > 15
Simple. first make sure there are common denominators. There is, thus, you can now subtract.
11/12-2/12.
11-2=9
and you don't subtract denominators.
Then, 9/12
you can simplify even more by dividing both the numerator and denominator by 3. So 9/3=3 and 12/3=4
So, in simplest form, your answer is 3/4.
9514 1404 393
Answer:
100°
Step-by-step explanation:
The relevant relation for angle x is ...
x = (AB +DE)/2
and for angle y, it is ...
y =(AC -DE)/2
Using the second relation to write an expression for DE, we have ...
DE = AC -2y
In the first equation, this lets us write ...
x = (AB +(AC -2y))/2 = (AB +(2AB -2y))/2
2x = 3AB-2y . . . . . . . . . . . . . . multiply by 2
(2x +2y)/3 = AB = AC/2 . . . . . add 2y; divide by 3
AC = (4/3)(x +y) = (4/3)(60° +15°) . . . . multiply by 2, substitute known values
AC = 100°
Bananas to apples = 12:8
= 12/8
= 3/2
I think it is 1.5 because if u ➗ it will give u 1.5
