This is the ACTUAL math problem: -2.3f + 0.4f - 16 - 9

HOW AM I SUPPOSED TO DO THIS

Answers

Answer 1
I think the answer is -2.7f-25 because if you subtract -2.3 F + .4 F then you do -16-9 I could be wrong warning
Answer 2

Answer:

− 1.9 f − 25

Step-by-step explanation:

You have to simplify the terms -2.3f + 0.4f and  16 - 9

Answers

Answer:

Step-by-step explanation:

The midpoint between two points is the average of the coordinates.

mp=((x2+x1)/2, (y2+y1)/2)

In this case we are given one end point and the midpoint.

Just look at the x coordinate first.

If the mid x is 8 and the x from j is 10 we have

(10+x)/2=8

10+x=16

x=6, now for the y for j when y=6 and mid y of 5

(6+y)/2=5

6+y=10

y=4

So the coordinates of K are (6,4)

Brainliest to whoever answers first!!!Z'(5, -7) is the image of Z after a reflection
in the line y=x. What are the coordinates
of Z?

Answers

Answer:

I think its Z (-5, 7)

Step-by-step explanation:

Here :)

The coordinates of Z is (7, -5).

Given that, Z'(5, -7) is the image of Z after a reflection in the line y=x.

We need to find the coordinates of Z.

What is the reflection in the line y=x?

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

So, the coordinates of Z become (7, -5).

Therefore, the coordinates of Z is (7, -5).

Answers

Answer:

Bill is 9.80 km apart from Concert

Step-by-step explanation:

It's given in the question,

m∠B = 75°

m∠C = 45°

By triangle sum theorem,

m∠A + m∠B + m∠C = 180°

m∠A + 75° + 45° = 180°

m∠A = 180° - 120°

m∠A = 60°

By sine rule,

[tex]\frac{\text{sin}(\angle A)}{BC}=\frac{\text{sin}(\angle C)}{AB}[/tex]

[tex]\frac{\text{sin}(60)}{BC}=\frac{\text{sin}(45)}{8}[/tex]

BC = [tex]\frac{8\text{sin}(60)}{\text{sin}(45)}[/tex]

     = 9.80 km

Therefore, Bill is 9.80 km apart from Concert.

What is XY? .........................

Answers

Answer: B i guess

Step-by-step explanation:

The hypotenuse side XY of given right angle at Z is [tex]5\sqrt{2}[/tex].

Given that in triangle XYZ :

∠X=45°

∠Y=45°

XY=5

And right angled at Z, that is, ∠Z=90°.

Since, ∠X=∠Y=45°

Therefore, XZ=YZ=5

Now,

[tex]\sin \theta = \dfrac{hypotenuse}{opposite}[/tex].

Here, θ=45°.

Therefore,

[tex]\sin \theta=\dfrac{5}{XY}\\\\\sin 45\°^=\dfrac{5}{XY}\\\dfrac{1}{\sqrt{2} } =\dfrac{5}{XY}\\\\XY=5\sqrt{2}[/tex]

Thus, the side XY=[tex]5\sqrt{2}[/tex].

How do I determine which method is used for this and what is it? (Thorough explanation please)

Answers

Answer:

x = -18

y = 4

Step-by-step explanation:

x + y = 4

2x + 3y = 30

You can do any math operation to each side of the equal sign as long as you do the same operation to both sides.

change x + y = 4       to        x = 4 - y  

Now substitute (4 - y) into the second equation, in place of x.

2(4-y) + 3y = 30

multiply the 2(4-y) part:

8 -2y + 3y = 30

simplify:

8 + y = 30

subtract 8 from each side:

y = 22

now substitute the value of y back into the first equation to solve for x:

x + 22 = 4

subtract 22 from both sides:

x = -18

Check:

x + y = 4

22 -18 = 4  

4 = 4       (this checks)

2(-18) + 3(22) = 30

-36 + 66 = 30

30 =30     (this checks also)

PS: you could have solved for y first if you had wanted to. The results would be the same.
