This is solved for all values of
y = -x-3. (Assuming you meant that 2x+2y=-6).
Answer:
1) solution is y = -7
2.) DNE
3.) Solution is y = -2
Step-by-step explanation:
1.) 2+3 = y + 12
Add the LHS and make y the subject of formula
5 = y + 12
Y = 5 - 12
Y = - 7
The solution of the equation is - 7
2.) 2 + 13 = 1 +8
Since there is no unknown variable and the sum of the numbers in the left hand side ( LHS ) is not equal to the sum of the numbers in the right hand side ( RHS ), it will be concluded that there is no solution in the equation.
3.) y - 7 = 2 - 11
Sum the RHS and make y the subject of formula
Y - 7 = -9
Y = -9 + 7
Y = -2
The solution of the equation is -2
If you use PEMDAS, you’ll start with multiplication. so 54*96=5,184. 6*2=12.
so now the problem would be 96+5,184+32/98-12.
from here you would divide.
so, 32/98=0.33 (rounded up)
now you add.
96+5,184+0.33=5,280.33
so, 5,280.33-12=5,268.33.
the answer is:
5,268.33
hope this helped!!
Answer:1547.9 miles per hour
Step-by-step explanation:
Let the two trains leave in x direction and y direction
Velocity of train in x direction be v
therefore velocity of train in Y direction is v+29
because one train is 29 miles per hour slower than other.
Distance travel by train in x direction is(x) v(2)
Distance travel by train in y direction is(y) 2(v+29)
distance between them after 2 hours is 4420 miles
Now using pythagoras theorem


on solving

v=
v=1547.889 miles per hour
