Answer:

<u>h</u><u> </u><u>is</u><u> </u><u>4</u><u>.</u><u>5</u>

Step-by-step explanation:

15 - 2h = 6

make 2h the subject:

- 2h = 6 - 15 \\  - 2h =  - 9

divide all sides by -2:

\frac{ - 2h}{ - 2}  =  \frac{ - 9}{ - 2}  \\  \\ h =  \frac{9}{2}  \\  \\ h = 4.5

Answer:

h=4.5

Step-by-step explanation:

15-2h=6   Get rid of any constants of the side of the variable.

<u>-15    -15</u>

-2h=-9      Divide -2 from both sides to isolate h.

<u>/-2  /-2</u>

h=4.5

Hope this helped you out! Have a wonderful day :)

Make up an equation of the form y = kx +b, the graph of which passes through the following points: A (8, –1) and B (–4, 17)
igor_vitrenko [27]

Answer:

One equation would be y= -1.5x +11

Step-by-step explanation:

Here's a table to show the coordinates

x:             y:

8              -1

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

-4             17

the x coor. 8  goes down by 12 to get to the next x coor. -4.

8-12= -4

the y coor. -1 goes up by 18 to get to the next y coor. 17.

-1+18= 17

therefore 18/-12 is -1.5 which can be your k in y=kx+b.

Check your answer.

-1.5*8= -12 but when you add 11, you get the y coor. -1

Do the same with the other x coor.

-4*-1.5= 6 + 11 =17

11 can be your b in the slope-intercept form equation.

One equation may be y = -1.5x +11

Anna is making a banner out of 4 congruent triangles as shown below. How much blue trim will she need for each side
Ede4ka [16]

Answer:

The length of each blue trim is 17.2 inches

Step-by-step explanation:

Given

See attachment for banner

Required

The length of each blue trim

Since all 4 triangles are equal, then the dimension of 1 triangle is:

Side\ 1 = 10

Side\ 2 = 14

The hypotenuse (x) of the triangle blue trim is represented by the blue trim

So:

x^2 = Side\ 1^2 + Side\ 2^2

This gives

x^2 = 10^2 + 14^2

x^2 = 100 + 196

x^2 = 296

Take square root

x = \sqrt{296

x = 17.2in

Shilpa bought 30 T-shirt at a clothing store. 20% of the t-shirt were blue and 1/2 of the t-shirts were black. Howmany of the t-
k0ka [10]
The number of T-shirt bought by Shilpa from a clothing store = 30
Percentage of T-shirt that were blue = 20%
Then Number of T-shirt that were blue in color = (20/100) * 30
                                                                           = 2 * 3
                                                                           = 6
Number of T-shirts that were black in color = (1/2) * 30
                                                                     = 15
Then
The total number of T-shirts that were black and blue = (15 + 6)
                                                                                     = 21
Then
The total number of T-shirts that were neither black nor blue = 30 - 21
                                                                                                 = 9
So the number of T-shirts that were neither black nor blue was 9.
