‘z’ is subtracted from (-12) express the expression​

Answer:

32 Kilometers

Step-by-step explanation:

A Car travels 80 Kilometers in 2 and Half hours.

1 Hour =60 minutes, 2 & Half hours= 2.5*60= 150 minutes

Kilometers travelled by Car in a hour= 80/150*60= 32 Kilometers

Answer:

Step-by-step explanation:

7: Area=77km^2

8: Not sure I think Area=77cm^2

9: Area=56m^2

10: Area=43.51km^2

Im not too sure of this problem but I hope this helps

Answer:

The cross section of a pyramid that is perpendicular to the base will be a triangle.

Step-by-step explanation:

Answer:

8) x=9

10) 23 degrees

Step-by-step explanation:

8) vertical angles are congruent to each other so we can set the expressions as such and solve:

7x + 3 = 10x - 24

3 = 3x - 24

27 = 3x

9 = x

10) since the angles are complementary they equal 90 degrees, so we can set the expression like this and solve for x:

12x + 7 + 6x - 7 = 90

18x + 7 - 7 = 90

18x = 90

x = 5

now we plug it back into the expression equivalent to the measure of angle O:

6(5) -7

30 - 7

23 degrees

Answer:

hey i hope u are having a wonderful day its gonna be ok

here is the answer:

Answer:

1. [tex]y=\frac{2}{3}x-2[/tex]

2. [tex]y=\frac{-5}{4}x+5[/tex]

Step-by-step explanation:

all you are doing is solving for "y"

Answer:

ans 1. -2x = -6-3y

-2x = 9y

xy = -2/9

ans 2. 5x = 20 - 4y

5x = 16y

xy = 5/16

I hope it helps....

Answer:

43 m. Perimeter is all the sides added together.

Answer:

Its should be 1 because the graph shows you thats its 1

I'm confused because...

Step-by-step explanation:

The area of the triangle is 117.

So the surface area of the pyramid is 701.168.

Answer:

t = 1/3

Step-by-step explanation:

for this problem we have two different shapes, what we need to do is find out the proportional relationship between the two to solve for t, lets take one of the measurements from the smaller shape, we will go with... JK at 5

now all we need to do is divide that by the larger shapes same side, in this case that would be RP at 22.5, heres what that looks like so far

5 / 22.5 = 0.2-> (the two goes on forever, normally this is represented by a line above the infinite number, this is what they call a Repeating Decimal)

ok, so now that we have the rate of change between the two shapes figured out, now we just make the same change to the last side from the same side on the first shape, wich is LK to QR as shown

1.5 * 0.2-> = 0.3->

and if 0.3 is = to 1/3, so t = 1/3

i hope this helped you out, im sorry if im a little late lol, make note that all of this can be applied to similar situations, just figure out the change(s) that happened from one shape to the other, and make that same change on the unknown side or area

take care :D

Answer:

65

Step-by-step explanation:

2x + 25 + 25 = 180

2x + 50 = 180

2x = 180 - 50

2x = 130

2x / 2 = 130 / 2

x = 65

I think it is the second one i am so so so sorry if it wrong

Step-by-step explanation:

Answer:

y=3x-3

Step-by-step explanation:

insert the first point into y=mx+b

3=2m+b

----------------

Do it again with the other point

6=3m+b

-------------

Now put both equations in a system of equations

3=2m+b

6=3m+b

solve for m and b

m=3 and b=-3

y=3x-3

m=slope

b=y-intercept

Answer:

#3

Step-by-step explanation:

The line follows an inverted slope format, indicated by -2/3. Or down 2, and 3 to the right after going up by 4, creating the line. The other equations would flip the line horizontally because of a positive slope.
