Answer:

4.05d+0.1i−4.2

Step-by-step explanation:

Let's simplify step-by-step.

1.6i+ 3/ 4 d−3( 1 /2 i−1.1d)−4.2

Distribute:

=1.6i+ 3/ 4 d+(−3)( 1/ 2 i)+(−3)(−1.1d)+−4.2

=1.6i+ 3/ 4 d+ −3/ 2 i+3.3d+−4.2

Combine Like Terms:

=1.6i+ 3/ 4 d+ −3/ 2 i+3.3d+−4.2

=( 3/ 4 d+3.3d)+(1.6i+ −3/ 2 i)+(−4.2)

=4.05d+0.1i+−4.2

Hope it helped!

2. XYZW is a parallelogram with diagonals XZ and YW that intersect at point A.

sergeinik [125]

Answer:

AW=10

Step-by-step explanation:

In a parallelogram opposite sides are congruent meaning XA and AZ are congruent. YA and AW are congruent. So...

Solving for XA and AZ

XA=AZ

3m=5m-4

-2m=-4

m=2

If YW=10m then 10 x 2 = 20

20 divided by 2 = 10

Explain how to add fractions with unlike denominators. Please be as specific as possible.

Gelneren [198K]

Answer:

Look below

Step-by-step explanation:

So I will use an example to try and show you how to do this.

If we have $1/2 + 1/3$ , we know that we don't have like denominators. We can change this by finding one. All we need to do is multiply our denominators. So in our example, that would be $2*3=6$ . Our new denominator would be 6. So now we would have $1/6 + 1/6$ which isn't the same as our old equation. That is because we haven't multiplied our top numbers yet. To do this, we need to multiply the top number by the opposite denominator like so, $3/6+2/6$ .

So our first fraction was

$1/2+1/3$

We then multiplied the whole fraction by the opposite denominator

$3/6+2/6$

Thanks! Hope you choose me for brainliest!!! Have a nice day!
