Answer: x= 80
Step-by-step explanation:
it’s an isoceles triangle so bottom 2 angles are 50
50+50= 100
180-100= x
4y - y + 7y
4y - y = 3y
3y + 7y = 10y
10y is your answer

Kid tickets = 3d
D = adult tickets
448 = (3 * d) + d
448 = 4d
448/4 = 112
112 = d
3 * d = 336
There are 336 kid tickets and 112 adult tickets sold.
Based on the number of times that Caleb writes checks, uses his debit card, and uses the ATM, his monthly bank fees are $11 and $15.70 at NeoBank and Arbor Bank respectively.
<h3>What are Caleb's bank fees?</h3>
The question is incomplete so I will use a similar question to answer it.
Caleb's fees at Neobank would be:
= (12 checks x 0 per check) + (10 debt card uses x 0 per use) + (6 ATM uses x 1 per use) + 5 Monthly fee
= 0 + 0 + 6 + 5
= $11
Caleb's fees at Arbor Bank:
= (12 checks x 0.10 per check) + (10 debt card uses x 0.25 per use) + (6 ATM uses x 2 per use) + 0 Monthly fee
= $15.70
