Selection D is the only one that works to give a1 = 12.5.
Answer:
C)78.5
Step-by-step explanation:
∠BOZ = X
∠WOB = 7X - 4
X + 7X -4 = 180 {STRAIGHT LINE }
8X = 180 + 4
8X = 184
X = 184/8
X = 23
∠WOB = 7X - 4 = 7*23 - 4 = 161 - 4 = 157
OA bisects ∠WOB. So, ∠WOA =∠AOB
∠AOB = 1/2 of ∠WOB = 157/2 = 78.5
Answer:
He had $56.
Step-by-step explanation:
$46 + $10 = $56
you can also solve it like this:
x = 46 + 10
x = 56
Answer:
1) x = -y + 5
y = - 3/5x + 3
2) y = 0
Step-by-step explanation:
In ax+by=c form
slope=-a/b
a paralel line has same slope
4x+y-2=0
4x+1y=2
slope=-4/1=-4
therefor the other line has to have a slopt of -4
y=mx+b
m=slope
b=y intercept
slope=-4
y=-4x+b
input a point tha we ar given (4,-3)
x=4
y=-3
-3=-4(4)+b
-3=-16+b
add 16
13=b
y=-4x+13
get to ax+by=c form
add 4y both sides
4x+y=13 is the euation
