The complement is equal to 90 so the complement to 70 is 20. the supplement adds to 180 so the supplement to 70 is 110. if you are talking about x... it’s an isosceles triangle so the base angles are the same and the angles in a triangle add to 180 so 180-(70+70)=40 so x=40 so the complements is 50 and the supplement is 150

Step-by-step explanation:

By angle sum property ,

x = 40⁰

Complement = 90 - 40 = 50⁰

Supplement = 180 - 40 = 140⁰

A phone company has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minu

jok3333 [9.3K]

Answer:

Linear equation for the monthly cost of the cell plan is $10+0.15x$

Step-by-step explanation:

Let u denotes a flat monthly fee and v denotes amount charged per minute.

As the monthly cost is $71.50 if a customer uses 410 minutes,

$71.50=u+410v$ (i)

As the monthly cost is $118 if a customer uses 720 minutes,

$118=u+720v$ (ii)

Subtract (i) from (ii)

$118-71.50=u+720v-u-410v\\46.5=310v\\v=\frac{46.5}{310}\\ v=0.15$

Put $v=0.15$ in (i)

$71.50=u+410(0.15)\\71.50=u+61.5\\u=71.50-61.5\\u=10$

As x denotes the number of monthly minutes used,

linear equation for the monthly cost of the cell plan is $10+0.15x$
