Previous question Rational numbers prior question delete your full name you accidently wrote in your question for rational numbers by pressing edit icon answered here so your edit is possible ok! Answer is -2t +7t = 5t Step-by-step explanation: question asks for addition only (4t-6t= -2t)+(8t-1t=7t) This question on page = 1) At 2:16 p.m.= -180ft - 40ft = -220ft 2) At 2:17 p.m = -175ft-40ft= -115ft 3) At 2:18 p.m. = -185ft - 40ft = -225ft 4) The difference is show your work by reversal 2:18-2:15 = 3 minutes so the distance is also reversed at (-225) - (-40 )= -225 + 40 = -175

Step-by-step explanation: This is minus - number minus- number = minus number counting bkwards but when when we subtract two minus number with another minus it becomes a plus + just between the brackets see question 4 brackets use. The work is using brackets for question 4.

Simplify.

bixtya [17]

Answer:

$\frac{3+i}{-2i}$ = -0.5 + 1.5i

Step-by-step explanation:

Given 3+i divided by -2i ⇒ $\frac{3+i}{-2i}$

By multiplying the numerator and the denominator by the conjugate of (-2i) which will be equal (2i)

So, $\frac{3+i}{-2i}$ = $\frac{3+i}{-2i} *\frac{2i}{2i} = \frac{i(3+i)}{-2i^2} = \frac{i^2+3i}{-2i^2}$

We should know that: i = √(-1) ⇒ i² = -1

∴ $\frac{i^2+3i}{-2i^2} = \frac{-1+3i}{-2*-1} = \frac{-1+3i}{2} = -0.5 + 1.5i$

∴ $\frac{3+i}{-2i}$ = -0.5 + 1.5i
