Answer:
x = 7
Step-by-step explanation:
The larger outside triangle and the smaller triangle on top are similar, hence the ratios of corresponding sides are equal, that is
=
= ( cross- multiply )
5(2x + 13) = 135
10x + 65 = 135 ( subtract 65 from both sides )
10x = 70 ( divide both sides by 10 )
x = 7
Given:
Anna’s cell phone plan charges her $30 per month plus a $150 one-time activation fee.
Evelyn’s cell phone plan charges her $20 per month, plus a $450 one-time activation fee.
To find:
The number of months after which the costs for the girls’ cell phone plans the same.
Solution:
Let x be the number of months.
Total cost = Fixed cost + Variable cost
According to the question, cost equation for Anna’s cell phone is
...(i)
Cost equation for Evelyn's cell phone is
...(ii)
Equate (i) and (ii) to find the time after which the costs for the girls’ cell phone plans the same.
Divide both sides by 10.
Therefore, the costs for the girls’ cell phone plans the same after 10 months.
You just need to multiply 35 by 2/7
35 x 2/7 = 10 so there are 10 blue socks
Answer:
The measure of angle A = 65°
Step-by-step explanation:
The sum of opposite angles of cyclic quadrilateral is 180°
From the figure we can see that,quadrilateral ABCD is inscribed in a circle.
<u>To find the value of x</u>
m<B + m<D = 180°
x + 148 = 180
x = 180 - 148 = 32°
<u>To find the value of angle A</u>
m<A = 2x + 1
x = 32
m<A = 2*32 + 1 = 64 + 1 = 65°
Therefore the measure of angle A = 65°
