Answer:
-9y + 7 = -9y + 6
Step-by-step explanation:
-9y + 7 = -9y + 6
Has no solution
add 9y to both sides
7 = 6 which is false
therefor no y exists that can result in a solution
X-2(-4)=2
X+8=2
-8. -8
X=-6. (-6,-4)
4-2y=2
-4. -4
-2y=-2
Divide both sides by-2
Y=1. (4,1)
Answer:
521418
Step-by-step explanation:
The value of x+y+z = 93
<u>Explanation:</u>
<u></u>
angle 1 = 18x
angle 2 = x+y
angle 3 = 30z
In rhombus, the diagonals intersect at 90°
Therefore,
angle 1 : 18x = 90
x = 90/18 = 5
angle 2: x+y = 90
5+y = 90
y = 85
angle 3: 30z = 90
z = 90/30 = 3
Value of x+y+z = 5+85+3 = 93
Thus, the value of x+y+z = 93
2 gallons 25% of 4 is 1 so there is about 1 gallon of pure in there no so adding two will make 3 gallons of antifreeze bringing total to 6 gallons 3/6 = .5 boom bam 50%
