Answer:
x=63
z=72, y=45
Step-by-step explanation:
Angles "z+y" and "x" add up to 180°, so they are supplementary angles.
angle B=72+b+63=180⇒b=180-135=45
angle B=72+45=117
angle A+angle B=180
x+117=180
x=180-117=63
angle D+angle A=180
z=72, y=45 alternate angles (opposite angle of parallelogram are congruent)
x+z=117 = angle B
Answer:
y= 3x+8
Step-by-step explanation:
y=3x+8

The formula for the circumference of a circle is π x diameter
Since we already know the circumference, we divide that by π to get the diameter:
circumference = π x diameter
so
circumference / π = diameter
Now lets do this:
31.4 / π = 9.9949... (this is the diameter)
-----------------------------------------------------------------------
The formula for the area of a circle is π r²
To get the radius, we just halve the diameter:
9.9949.. / 2 = 4.99746...
Now that we know the radius we can use the formula:
π x r²
= π x 4.99746²
= 78.46ft²
So the area is:
78.46ft²
Bode paid on average $1200 × 11% = $132 each month in interest. If Bode made 12 mortgage payments last year, he paid
... 12 × $132 = $1584
in mortgage interest.
Kecia has 12 nickels and 9 dimes.
This is true because...
12 x 5 = 60
9 x 10 = 90
90 + 60 = 150
In other words $1.50
