When Legs jumps 2 times and takes 13 steps forward, he lands in the same place as when he jumps 4 times and takes 5 steps backwa
tangare [24]

Answer:

9 steps

Step-by-step explanation:

Let x be the number of jumps

and y be the number of steps

So the first case

2x+13y

Second case

4x-5y

Both cover equal distances so

2x+13y=4x-5y

\Rightarrow 2x-4x=-5y-13y

\Rightarrow 2x=18y

\Rightarrow x=9y

So, one jumps is 9 steps.

Oil that costs 22.50/barrel is mixed with oil that costs 35.00/barrel. How many barrels of each oil should be included in 1250 b
timama [110]
So 22.5 per barrel



so 22.5
x represents the number of 22.5 barrels

y represents the number of 35 barrels

so
x+y=1250

then find the total cost
1250 barrels
27.5 per so mutiply by 1250 and get 34375 total cost

22.5x+35y=34375

we have 2 senctances
x+y=1250
22.5x+35y=34375

elimination
mulitply first equation by -35 to clear y
-35x-35y=-43750
add to second equation
-35x-35y=-43750
<u>22.5x+35y=34375    +</u>
-12.5x+0y=-9375
-12.5x=-9375
multiply -1
12.5x=9375
divie both sides by 12.5
x=750


subsitute
x+y=1250
750+y=1250
subtract 750
y=500


750 barrells of the 22.5 oil should be included and
500 barrells of the 35 oil should be included

217+37(3x−5)=−4 Drag and drop the statement that shows the solution to the equation into the box.
babunello [35]
Distribute on the left
217+111x-185=-4

Combine like terms
111x+32=-4

Sybtract 32 from both sides
111x=-36

Divide both sides by 111
x= -36/111
x=-12/37

Final answer: x=-12/37

Which points are a distance of 5 units from (2, 3) if d = square root (x2 - x1)2 + (y2 - y1)?
qwelly [4]

Answer:

Step-by-step explanation:

hello :

note :

note : distance between A(X1,Y1) an B (X2,Y2) is :  

AB= √((X2 - X1)² + (Y2 - Y1)²)    (given point  B(2 , 3)

in this exercice : X1 = 2     X2 = ?      Y1 = 3      Y2 = ?   d=AB=5

d² = (X2 - 2)² + (Y2 - 3)² =25

the points are a distance of 5 units from B (2, 3) if d = 5 :

the points are located on a circle with center B and radius 5
