Hi!

<h3>First, we can remove the parentheses. </h3>

-3 - i + 5 + 6i

<h3>Combine like terms</h3>

-3 + 5 - i + 6i

-3 + 5 - 1i + 6i

<h3>Now to make it easier for you, I will add parentheses again. </h3>

(-3 + 5) + (-1i + 6i)

<h3>Solve inside the parentheses</h3>

(2) + (5i)

<h3>Remove the parentheses once more</h3>

<h3>And there's your answer!</h3><h2>The answer is 2 + 5i</h2>

Hope this helps! :)

Mary wants to put 1/10 of a kilogram of bird seed in each of the bird cages in her pet shop. She has 3/10 of a kilogram of bird

alex41 [277]

Answer:

A) 3

Step-by-step explanation:

If you simply look at the given numbers, it should be pretty clear that 3 tenths is 3 times 1 tenth.

When Mary puts 1/10 kg in each cage, she can do that for 3 cages with 3/10 kg of bird seed.

If you let c represent the number of cages, then the amount of bird seed used will be (1/10)c. This will be equal to the amount available when we use it all for filling cages:

(1/10)c = (3/10)

Multiply both sides of the equation by 10:

c = 3

Mary can fill 3 cages with available seed.

I’ve been stuck can someone explain

MariettaO [177]

Answer:

Option (3)

Step-by-step explanation:

From the figure attached,

AB and CD are two chords intersecting at O.

m∠AOD = 37°

m∠AOC + m∠AOD = 180° [Since these angles are supplementary angles]

m∠AOC = 180° - 37°

= 143°

By the theorem of intersecting chords,

Measure of angle formed is the half of the sum of measures of the arcs intercepted by the angle and vertical angle.

m∠AOC = $\frac{1}{2}(\widehat{AC}+\widehat{BD})$

143° = $\frac{1}{2}[(x+5)+(x-5)]$

143° = x

Therefore, Option (3) will be the answer.
