Solve:
t + 15 = 5

-4 = p - 6

5/y = -2

84 = 7d

three times a number is less than or equal to 12

Four less than a number is greater than negative one

n≤−4

k >5

1/2 x = 5/6

0.3a = -51

Please Show all work.

-10 is the correct answer

Step-by-step explanation:

t+15=5

-15 -15

t= -10

(1) t + 15 = 5

    5 - 15 = t

     t = -10

(2) -4 = p - 6

    -4 + 6 = p

    p = 2

(3) 5/y = -2

    5 ÷ -2 = y

    y = -2.5

(4) 84 = 7d

     84/7 = d

    d = 12

(5) three times a number is less than or equal to 12

      3n < 12

     12/3 = n

      n = 4

(6) Four less than a number is greater than negative one

      4 - p > -1

     4 + (-1) = p

     p = 3

(7) n≤−4

i dont know what to do for this equation

(8) k >5

i dont know what to do for this equation

(9) 1/2 x = 5/6

    5/6 ÷  1/2 = x

    x = 5/3

(10) 0.3a = -51

    -51 ÷ 0.3 = a

     a = -170

Hope this helps

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
