Answer:

x=5

Step-by-step explanation:

If the sum of the measures of angle M and R is 90 degrees, and you know that angle R is 55 degrees, subtract angle R from the total angle. Then, solve for M

90 - 55 = 35

5x + 10 = 35

5x = 25

x = 5

-114=-5x-2(4x+18)<br> ????????

SVETLANKA909090 [29]

Primeiro multiplica o -2 com tudo que tem dentro do parenteses (chuveirinho) -114 = -5x -2(4x+18)

-2 . 4x = -8x + -2 . 18 = -36 = -8x-36

Agora soma os números com incógnitas (no caso x)

-114 = - 5x - 8x -36

Joga a incógnita do outro, tornando positiva

-114 = -13x - 36

13x -114 = -36

e o 114 do outro lado, ficando positiva também

13x -114 = -36

13x = - 36 + 114

13x = 78

x = 78 /13

x= 6

The set of points R(-1, 1), S(2, 4), T(6, 8) are collinear. true or false

Harlamova29_29 [7]

R, S and T are collinear if they are in the same exact line.

It is enough to show that slope of RS is equal (or not) to the slope of ST,

slope of RS $=m_R_S= \frac{4-1}{2-(-1)}= \frac{3}{3}=1$

slope of ST $=m_S_T= \frac{8-4}{6-2}= \frac{4}{4}=1$

the lines through R, S and S, T have the same slope so the three points are collinear.

Answer: TRUE
