1. 5x-y=4
2. -4/3+1/3y-2/3z
3. x=5+1/2y -3/2z
And/or the answer to the whole thing could be that the statement is incorrect.
Answer:
<h2>APPLY THIS METHOD→→</h2>
- x+y=4 ___(1), 2x−5y=1__(2)
multiply eq. (1) by 2.
and then subtract eq. (2)
2x+2y=8
2x−5y=1
- + -
____________
7y=7
y=1
x+y=4
x+1=4
x=3
Answer:
S
Step-by-step explanation:
Answer:
<h2>The answer is 15 units</h2>
Step-by-step explanation:
The distance between two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(5, -5) and (-7,4)
The distance between them is
We have the final answer as
<h3>15 units</h3>
Hope this helps you
(A) 10:20 - 10:45
45-20= 25 min
(B) average speed = distance / time
25min/ 60 = 0.42hr
75 km/ 0.42 hr = 178.57 km/hr
Ans: 178.57 km/hr
