Answer:

2 3/4

<u> - 3/7</u>

 3 5/28

Step-by-step explanation:

First, Find the common denominator of 4 and 7 which is 28. 28 will be the denominator of your difference.Then, now time to multiply, now you multiply 7 by 21 because you multiplied 7 by 4  to get 28. You do the same for the others one but a bit different because this time you multiply 4 by 3= 12 now you have 21/28 and 12/28. Now you add 21 and 12 not 28 because you don't multiply denominators in this case. After that you get 33/28, this is an improper fraction so you divide. 28 goes into 33 once so you have a whole number 1 then you have 5 left over making it the numerator. Result 1 5/28, because you have the whole number 2 left from the equation you add it ending up with 3 5/8

Hope this helps :D !!

Answer:

(00)^{*} | (00)^{*}  1 (00)^{*}

Step-by-step explanation:

The best way would be to have 00 begin then a 1 and 00; starting with the possibility of 00 or 1 means that we might not get 1 in some formation.

How to find the value of x and z
Setler79 [48]

Answer:

z = 86 °

and, x = 2

Step-by-step explanation:

We know that a straight line is a 180 degree-angle. So, we know that

94 + z must equal 180, because they are the only two angles that make up the straight line.

from this information, (that 94 + z = 180) we can easily find z.

(this is typically an intuitive method of subtracting 94 from 180)

94   +   z   =   180

-94                  -94

z = 86 °

-- we know that the relation between z and (10x + 74) must also be equal to 180, as they make up a straight line

if z = 86, then we can know that (10x + 74) must be equal to

(10x + 74) + 86 =    180

                - 86        -86

(10x + 74) = 94

10x + 74 = 94

      - 74   - 74

  10 x     =    20

÷ 10            ÷ 10

     x    =   2

so, z = 86 °

and, x = 2

(I am assuming that this "unprotected placement assessment" has already taken place, and you would like to understand a question. Or, this is a practice assessment. Because there is no point to cheating on a placement assessment--you will just skip over material you don't know. And, it wouldn't align with Brainly's honor policy. Hope you learn from this!!)

Help me with this geometry
KiRa [710]

Answer:

x= (5X+3) DEGREES = 90 degrees (right angle)

5x=90 degrees - 3 degrees =87 degrees

5x÷5 =87 degrees ÷ 5

x=17.4 degrees

we now know our angles x = 17.4 degrees so we can know substitute into the give formula

wxz=5 (17.4)+ 3

wxz =90 degrees

zxy=we know the size of x

zxy=

8 (17.4)-4

zxy=135.2 degrees
