Angle 3 = angle 7 [alternate angles]
=> 4x+1 = 2x + 21
=> 4x-2x = 21-1
=> 2x = 20
=> x = 20/2
=> x = 10
After 19 months, the cost will be same for both memberships.
Step-by-step explanation:
Given,
Sign up fee at Power Plus = $22.00
Per month fee = $34.14
Let,
x be the number of months.
P(x) = 34.14x + 22
Sign up fee at Heavy Hulk = $34.50
As they have cut the cost into half.
Sign up fee = 
Per month fee = $34.39
H(x) = 34.39 + 17.25
For same cost ;
P(x) = H(x)
Dividing both sides by 0.25
After 19 months, the cost will be same for both memberships.

Answer:
measure of other diagonal is 30cm
Step-by-step explanation:
let the other diagonal be d .
- area of rhombus = 1/2 × 16 × d
- 240 = 8 × d
- d = 240 / 8
- d = 30
hence the other diagonal = d = 30 cm
Literally plugging in the time for each value, we can plug in 5 for t to get
22000+(-480*5)=22000+(-2400)=22000-2400=19800
Plugging in 10, we get 22000+(-480*10)=22000-4800=17200. We can turn 22000+(-480*10) into 22000-(480*10) using the distributive property, and adding a negative number to something essentially means to subtract that number.
I challenge you to do t=15 and 20 on your own!
