What is the measure of arc PQ​
Anni [7]

Answer:

x = 15

arc PQ = 110°

ΔPQR is an acute triangle

Step-by-step explanation:

(6x) + (8x-10) + (10x+10) = 360°

combine like terms:

24x = 360°

x = 15

arc PQ = 8(15) - 10° = 110°

+3.6-(-1.5)+(-6) need this simplified:)
inna [77]
3.6 - (-1.5) + (-6)   -> 3.6-(-1.5) is the same is 3.6 + 1.5. 

Tip: -(- looks like a + 

So, 
3.6 - (-1.5) + (-6)
3.6 + 1.5 + (-6)
5.1 + (-6)
5.1 - 6
= -0.9

Which compound sentence has its solution set shown on the graph below?
gogolik [260]

There might be a simpler way to do this, if there is, sorry.


If you look at the graph, x is greater than 3 but less than 5.

So: x > 3 and x < 5


I would simplify each solution set and get "x" by itself (until I get the right answer):

A.) 2x - 4 > 6 or 3x < 9

2x - 4 > 6    Add 4 on both sides

2x > 10      Divide 2 on both sides

x > 5        (you could stop here and go to the next choice since you know this does not match the graph)


3x < 9     Divide 3 on both sides

x < 3


x > 5 and x < 3


B.)   2x - 4 < 6 and 3x > 9

x < 5   and    x > 3


Your answer is B or the 2nd option

[C and D would have given a negative number]
