Answer:
Colton solved 9 math problems and read 18 pages.
Step-by-step explanation:
9*2=18
9 problems * 3 minutes per problem= 27 minutes
18 pages * 1.5 minutes per page= 27 minutes
27 + 27=54
The best way to solve is by trial and error and just testing out different numbers to see if they will work.
Answer:
Point form : (1,-4)
Equation for, : x=1, y=-4
Step-by-step explanation: Add the fractions in order to solve for the first variable. Plug this vale into the other equations in order to solve for the remaining variables.
Hope this helps you out! ☺

sen x = 3/5 eleva ao quadrado ambos os lados
sen² x = (3/5)²
Tem que partir da relação fundamental
sen²x + cos²x = 1
(3/5)² + cos² x = 1
cos² x = 1 - (3/5)² = 16/25
cos x = V(16/25 = 4/5
b ) tg x = sen x / cos x = 3/5 / 4/5 = 3/5 * 5/4 = 3/4
c) cotg x = cosx / sen x = 1 / tgx = 1/ (3/4 = 4/3
d) sec x = 1/ cos x = 1 / 4/5 = 5/4
e) cossec x = 1 / sen x = 1/ 3/5 = 5/3

Answer:
x = -8
Step-by-step explanation:
to solve this kind of problem is very simple , just be very careful about the negative and positive signs.
-7+2x = -6x -71
we will collect the like terms or simply say that you will combine the like terms
we have,
-7 + 2x + 6x = -71
2x + 6x = -71 + 7
8x = -64
divide both sides by 8
8x/8 = -64/8
x = -8
