What is the answer to this equation: 7.4 - 9 - 2r =18

lorasvet [3.4K]

We can get the answer to this equation by solving for the variable (r).

7.4 - 9 - 2r = 18

We want to get r on one side, so we want to push everything else to the other side.

-2r = 18 - 7.4 + 9

-2r = 19.6

2r = -19.6

r = -9.8

sesenic [268]

There are 200 students in the group.

To find this, you divide 70 by 0.35 (35%). This will give you 200. To check this, multiply 200 by 0.35 and you will get 70. Thus making 200 the answer.

I hope this helps!

Examine the fraction 3+2i4−2i. Which expression is the first step to simplify the fraction? 3+2i4−2i⋅3−2i3−2i

umka2103 [35]

Answer:

The correct answer is the last option.

Step-by-step explanation:

When you have a fraction with complex numbers, the first step to simplify is to multiply up and down the conjugate of the denominator, this will eliminate the complex part of the denominator, and in this way you can separate the expression in its real and complex part.

For the expression:

$\frac{3 + 2i}{4-2i
}$

The denominator conjugate is 4 + 2i

When multiplied, the denominator is:

$4 ^ 2 -4i ^ 2 = 16 -4 (-1) = 20$
