To get 3 5/6 - 4 5/12, you would have to get the denominators even. So 12 is the lowest, so lets use that.
3 5/6 - 4 5/12
3 10/12 - 4 5/12
3-4= -1
10-5= 5
Now, you have a -1 and a + 5/12, to do this you have to turn -1 into -12/12
-12/12 + 5/12 = -7/12
Your answer is -7/12
Hope this helped!
<span>y + 4 ≤ 0
----------------------
Subtract 4 from each side
</span><span>y + 4 - 4 ≤ 0 - 4
</span>y ≤ -4
y ≤ -4 is the answer

Answer:
30x +25y = 148
Step-by-step explanation:
We can use substitution to find the point of intersection of ...
Using the second equation, we can write an expression for y:
y = 6 -x
Substituting that into the first equation gives ...
3x +14 = 2(6 -x)
3x +14 = 12 -2x . . . . . eliminate parentheses
5x = -2 . . . . . . . . . . . add 2x-14
x = -0.4 . . . . . . . . . divide by 5
y = 6 -(-0.4) = 6.4
__
Now, we want an equation for a line through the point (-0.4, 6.4) that is perpendicular to 5x = 6y+1
The perpendicular line will have the coefficients swapped with one of them negated. The constant will accommodate the given point.
6x = -5y + c
6(-0.4) +5(6.4) = c = 29.6
The perpendicular line can be written ...
6x = -5y +29.6
In standard form, the equation is ...
30x +25y = 148
2 + 0.8
oof the first time i did it, i was thinking of something else
sorry
Elimination
2x+2y=10
2x-3y=5
multiply first equatn by -1
-2x-2y=-10
add to second equation
2x-3y=5
<u>-2x-2y=-10 +
</u>0x-5y=-5
-5y=-5
divide both sides by 5
-y=-1
muitply b-1
y=1
subsitue
2x+2y=10
2x+2(1)=10
2x+2=10
subtract 2
2x=8
divide 2
x=4
x=4
y=1
solution in (x,y) form is
(4,1)
