so what do u need help with?
Answer:
Thus the prime factors of the given numbers can be only 2, 3, 5, and 7. ... most 3 + 1 + 1 + 1 = 6 numbers, we are left with at least three numbers among the nine ... points, and b by blue points (for these inequalities to hold we might have to ... 8. The constant function f (x) = k, where k is a positive integer, is the only possible.
Step-by-step explanation:
Answer:
a. x=11°
b. ABC=106°, BCA=33° and BAC=41°
c. Sorry but I can't see the lines l and m
Step-by-step explanation:
a. the question stated that the sum of the measures of the angles in the triangle is 180°
so therefore equate all the values in the triangle to 180°
(9x+7)+ 3(x) + (3x+8)=180°
15x+ 15=180
15x=180-15
15x=165
Divide both sides by 15
therefore x=11
b. ABC=(9x+7)
where there is x put the x value you solved for there which is 11
therefore ABC=(9×11+7)= 106°
Do the same for BCA and BAC
This problem can solve by the rule of three.
42 installations-----------------------6 hours
147 installations---------------------- x
x=(147 installations * 6 hour) / 42 installations=21 hours.
Answer: 21 hours.
<span>Lets first solve this:-
52 + 33 = 85
Now we need to find something equivalent to this. We can work it out like this:-
33 - 3 = 30
52 + 3 = 55
30 + 55 = 85
So, 52 + 33 = 30 + 55.
Hope I helped ya!! xD </span>
