Ok for 22 you just have to add both of them together and set them to equal 90. ( 4z+ 3z+6=90). then you solve for z by combining like terms giving you 7z+6=90 then subtract 6from both side leaving you with 7z=84. then divide to get z=12. you thin plug 12 into the angles such as 4(12) and 3(12)+6 which give you 48 and 42 degrees and to double check just add your 2 degrees together to form 90.

on problem 20, add both angles together and set to 180 (4h+5+8h-5=180) since the line is like half a circle. then combine like terms (12h=180) divide by 12 and then after dividing 180 by 12 and getting 15 you substitute 15 in for h.

2x + 6 = 4x/2 + 12/2

To solve this, we need to transpose like terms to the same side.

2x - 4x/2 = 12/2 - 6

2x - 2x = 6 - 6

0 = 0

Since both sides are zero, it means that the equation has infinite number of solutions.

What is the greatest common factor of 90, 126, 180 and 990?
mylen [45]

9514 1404 393

Answer:

  18

Step-by-step explanation:

90 = 18·5

126 = 18·7

180 = 18·10

990 = 18·55

The greatest common factor of these numbers is 18.

<em>Comment on the GCF</em>

It can be useful to know Euclid's algorithm for finding the GCF:

  1. Determine the remainder from dividing the larger number by the smaller.
  2. If the remainder is zero, the smaller number is the GCF. If the remainder is non-zero, use it to replace the larger number and repeat from step 1.

For example, 126 mod 90 = 36; 90 mod 36 = 18; 36 mod 18 = 0, so 18 is the GCF of 126 and 90. (The modulo function 'mod' returns the remainder from division.)

If 1/2x+1/3=4 What is the value of 3x+2y
ivolga24 [154]

Answer:

x=3/22 ; y=-9/44

Step-by-step explanation:

1/2x+1/3=4

=>1/2x=4-1/3

=>1/2x=(12-1)/3

=>1/2x=11/3

=>22x=3

=>x=3/22....(1)

then,

3x+2y

2y=-3 . (3/22)

y=-9/44
