(2+___i) + (___+3i) = 6 + 8i

Answers

Answer 1

Answer:

(2+  5i) + (4 + 3i) = 6 + 8i

Step-by-step explanation:

2 + xi  + y + 3i = 6 + 8i

(2 + y) + xi + 3i = 6 +8i

(2 + y) + (x + 3)i = 6 + 8i

Compare real numbers

2 + y = 6

     y = 6 - 2

    y = 4

Compare imaginary numbers

x + 3 = 8

     x = 8 - 3

    x = 5

Stores often mark up items each year to cover inflation.
Last year, a CD at Juan's Tunes cost $12.95. This year,
the cost was marked up 8%. The store also gave anyone
who bought four CDs this
year a 10% discount. Explain
the steps to find the final cost for the four CDs this year.

Answers

Answer:

so you have $12.95. then you multiply it by 8% which gives you $13.986. Then you take 10% off of it, which gives you $12.5874.

Answer:

The new price would be 108% of last year’s price. Multiply the new price by 4 and then multiply that amount by 90% to find the sale price.

Garett uses 5 apples to bake an apple pie. On sunday, he bakes 2 pies. How many apples does Garett need on Sunday. Write an equation that could be use to find the answer to this problem.

Answers

To work it out, use ratios.
If
2
pounds of apples are required to make
5
pies, then
20
pies, which is
4
times as many pies you are making, will also require
4
times as many apples.
Therefore,
2
×
4
=
8
You will require
8
pounds of apples.
Garrett needs 10 apples on Sunday. The equation is 5+5=10 or 5x2=10.
5 apples = 1 pie
Garrett needs to make two pies so 5x2 or 5+5
5+5=10/5x2=10

Answer: False

Step-by-step explanation:

Economic equilibrium simply refers to a scenario where the economic forces are equal and balanced. It is the condition whereby the demand and the supply of goods and services are equal.

We should note that economic equilibrium is only theoretical. In reality, this isn't true as the market doesn't reach equilibrium, Eben though it moves towards it.

Therefore, the statement in the question is false.
