Y + 9d = (5) + 9(7) = 68
12/68 = 6/34 = 3/17
The solution is 3/17

In triangle ABC angle "A" equals 92° and "C" equals 24°. Whats the exterior angle of "B"?

garik1379 [7]

Hey there! :D

All angles in a triangle equal 180 degrees. An exterior angle is supplementary to the interior angle next to it. (also equal to 180 degrees)

92+24+<B= 180

116+<B= 180

Subtract 116 on both sides.

<B= 64

So,

180-64= 116

The exterior angle of <B is equal to 116 degrees.

I hope this helps!

Units are simplified first when measurements are multiplied because the units can sometime be very large or small and do not have to be exact when measurements are precise.

It costs $50.00 to deliver 6 floral arrangements. It costs $80.00 to deliver 12 floral arrangements. What is the constant rate o

german

The constant rate for 1 floral arrangement is $5.00 and inital value is $20.00

Equation: f(z)=20+5z

Step-by-step explanation:

Given,

Delivery cost of 6 floral arrangements = $50.00

Delivery cost of 12 floral arrangements = $80.00

Let,

x be the constant rate for each floral arrangement.

y be the initial value.

According to given statement;

6x+y=50.00 Eqn 1

12x+y=80.00 Eqn 2

Subtracting Eqn 2 from Eqn 1

$(12x+y)-(6x+y)=80.00-50.00\\12x+y-6x-y=30.00\\6x=30.00$

Dividing both sides by 6

$\frac{6x}{6}=\frac{30.00}{6}\\x=5.00$

Putting in Eqn 1;

$6(5.00)+y=50.00\\30.00+y=50.00\\y=50.00-30.00\\y=20.00$

The constant rate for 1 floral arrangement is $5.00 and inital value is $20.00

Equation for the function;

Let z be the number of floral arrangements.

f(z) = initial fee + 5*Number of floral arrangements

f(z) = 20+5z
