Answer:
10 minutes
Step-by-step explanation:
This is somewhat of a trick question and also incomplete.
Assuming he walks his dog 1/6th of an hour each week, he walks his dog 10 minutes per week.
If this is incorrect please tell me the complete question
Answer:
<em><u>x=-6, y=-2</u></em>, (As a point) (-6, -2).....The point form is not necessary unless you want to solve the system (of equations) by graphing.
Step-by-step explanation:
By substitution:
x-y=-4 By adding y on both sides,
x=y-4
Now you can substitute x for the expression (y-4)
Plug the (y-4) as x in the other equation.
So -2x+3y=6 becomes
-2(y-4)+3y=6
Now solve:
-2(y-4)+3y=6 distributes out to be
-2y+8+3y=6 Now combining like terms
y+8=6 Subtract 8 on both sides to isolate the variable
<u><em>y=-2</em></u>
Now plug the value -2 in where the y is in any equation (preferably the easier/less complicated one) and solve for x.
So x-y=-4 becomes
x-(-2)=-4
=x+2=-4
=<u><em>x=-6</em></u>
Answer: 12.25
Explanation:
Answer: 6(17+14) or 186
Step-by-step explanation: I provide with you two answers since not sure what u mean .And the first answer is distributive it and the second answer is the sum.
Also 102 + 84 is an expression already so I don't know what your asking and if this help u are welcome !
