I don't understand the y after the 4... but would it be x=2 y=1 ?

X is 2 and y is 1 ;)

You know 4 is really close to six, so even if you put y as two, 4x2 is 8 and you can't add anything to get to six, so you can automatically tell it is 1.
Knowing that, you can easily solve X.
Ask yourself "What do you add to 4 to get 6?) and you get 2.
In the next problem, 1+2 is 3, which proves your answer.

Hope this helped

It takes the high-speed train x hours to travel the z miles from Town A to Town B at a constant rate, while it takes the regular
tatyana61 [14]

Answer:

S=  z (y-x)/(x+y)

Step-by-step explanation:

Lets the speed of high speed train = u

Lets the regular speed train = v

We know that

Distance = Speed x time

For high speed train

 z = u .x      

    u= z/x                  ----------1

For regular speed train

 z = v .y    

v = z/y             -------------2

Both are traveling in opposite direction so relative speed

Vr = z / x+ z /y

Lets in time t they will meet

z = (z / x+ z /y) t

t= xy/ (x+y)

Lets take distance  cover by high speed train is m when it moves A to B and  speed cover by regular train is n when it is moving B to A.They meet at time t.

m = u .t

m = z / x .xy/ (x+y)

m = zy/ (x+y)            -----------3

n = v .t

n = z / y .xy/ (x+y)

n = zx/ (x+y)              -----------4

From equation 3 and 4

So

m - n= zy/ (x+y)   - zx/ (x+y)      

S=  z (y-x)/(x+y)

Option a is correct.

Janell ran a race 11.4 seconds faster than Hilda. Hilda ran the race 7.2 seconds slower than Gracie. If the average (mean) of th
yulyashka [42]

Answer:

X= Gracie

X+7.2=Hilda

X+7.2-11.4=Janell

(X+X+X+7.2+7.2-11.4)÷3=62.6

(3x+3)÷3=62.6

3X+3=187.8 (I arrive at 187.8 because I multiple 62.6 by 3)

3X=187.8-3

3X=184.8

3X/3=184.8/3

X=61.6

Step-by-step explanation:

GRACIE X=61.6

Hilda X+7.2=61.6+7.2=68.8

Janell X+7.2-11.4=61.6+7.2-11.4= 57.4

Consider the expression 12 + 12/13. Using words explain what this problem means. Solve and defend you answer.
Tems11 [23]
This problem is stating that 12 should be added to the quotient of 12 and 13. Since PEMDAS is an expression ' golden rule, first you would divide 12 by 13 to get an approximate answer of 0.92. Then, you would add 12 to 0.92. The sum of 12 and 0.92 is 12.92.
