Mathematics

qaws [65]3 years ago

Answer:

B. 52°

Step-by-step explanation:

You need to add both equations and set them equal to 90 degrees because the other side is 90 degrees and the entire line must equal 180.

So...

5x-22+4x+4=90\\

Combine like terms

5x+4x= 9x and -22+4= -18

So:

9x-18=90\\

Add 18 to both sides

9x=108\\

Divide 9 on each side to get X=12.

Then you must plug in the 12

(4(12)+4)\\(48+4)\\52

5 - 6 - 9 - 8 - 5 - 4 + 5 - 5 -5 -5 - 32 = ?
musickatia [10]

5 - 6 = -1

-1 - 9  = -10

-10 - 8 = -18

-18 - 5 = -23

-23 - 4  = -27

-27 + 5  = -22

-22 - 5 = -27

-27 -5 = -32

-32 -5  = -37

-37 - 32 = -69

Makovka662 [10]

Answer: 64% of garbage was plastic over there when he was collected garbage.

Step-by-step explanation:

Since we have given that

Total amount of garbage collected by them = 25 pounds

Total amount of garbage which consisted of plastic = 16 pounds

Percent of the garbage was garbage is given by

\frac{ plastic}{total}\times 100

=\frac{16}{25}\times 100\\\\=16\times 4\\\\=64

Hence, 64% of garbage was plastic over there when he was collected garbage.

What is the domain of the function graphed below?​
vlabodo [156]

Answer:

x < 7

Step-by-step explanation:

the domain of a function defines the valid x values for the function.

as we go from left to right through all possible values of x, we see all values incl. x=-1 are creating a valid function result (y) for this function. until we reach x=7.

the empty ball indicates that there is no y value defined here. and for any value x>7 there is no y value defined.

so, x < 7 is the right one.
