So 10/2 simplified is 5/1 which is on point 5. -9/2 is already simplified so in decimal form it is -4.5 which is -4 1/2, so you go down from 0 and mark it right where the BLUE dot is and the GREEN dot is 5/1. Hope this helps! :)

Mark and Trisha are traveling in the same direction and Mark is going 16 miles per hour. Trisha is going 12 miles per hour but s

Lorico [155]

Answer:

32 miles

Step-by-step explanation:

Given data

Let the total distance be x miles

Marks speed= 16miles per hour

Trisha's speed= 12 miles per hour

Trisha has covered 8 miles and has (x-8) miles to finish line

We know that

Speed= distance/time

time= distance/speed

Hence the time taken for Mark to finish is

time= x/16---------------1

The time taken for Trisha to finish is

time= (x-8)/12-----------2

equate 1 and 2 above

x/16= (x-8)/12

cross multiply

16(x-8)= 12*x

16x-128= 12x

collect like terms

16x-12x= 128

4x=128

x= 128/4

x= 32 miles

Hence they will meet at exactly 32 miles along the way

X°,Y° and Z° are three angles lying on a straight line.If X°=2y° and Z°=3y°,find he value of y

maks197457 [2]

Answer: " y = 30° " .
_____________________________________
Note: The sum total of the measure of all angles lying on a straight
 line is 180°.

So; x + y + z = 180 .

Given: x = 2y ;
 z = 3y ;
__________________
Find the value of: " y " ;
_______________________
Since: x + y + z = 180 ;

Substitute: "2y" for "x" ;
 and: "3y" for "z" ;
_______________________
 2y + y + 3y = 180 ;

 6y = 180 ;
______________________
Divide EACH SIDE of the equation by "6" ; to isolate "y" on one side of the equation; and to solve for "y" ;
___________________________
 6y/ 6 = 180 / 6 ;

 y = 30 ;
____________________________
Let us check our work;
____________________________
 2y + y + 3y = 180 ;

Substitute our solved value: "30" ; for "y" ; in the equation; to see if the equation holds true:
____________________________
2(30) + 30 + 3(30) =? 180 ?
____________________________
 60 + 30 + 90 = ? 180 ?
____________________________
 90 + 90 = ? 180 ? Yes!

Help i tried and cant get the answer lol

zloy xaker [14]

Answer:

$209 \frac{3}{4} - {3}^{2} \times (8 {}^{2} - 38 \frac{1}{2} ) \\ = 209 \frac{3}{4} - 3 {}^{2} \times 25 \frac{1}{2} \\ = 209 \frac{3}{4} - 229 \frac{1}{2} \\ = - 19 \frac{3}{4}$
