Need a little help please !
Answer:
x=11
Step-by-step explanation: since all the angles in the triangle equal 180, you take the angle you already have, 76, But because the sides are equal, the angle adjacent to the 76 is also 76. Now you add 76 and 76, 152, then you subtract that from 180, which is 28. You now take the 28 and put it equal to the 3x-5 and solve for x.

A store called Surfmania sells a $170 surfboard for 30% off. Another store, Coolwaves, advertises the same $170 surfboard for 10% off, but then offers to reduce that sale price by 20%. Which store has the better deal, and what is the savings compared to the other store? Surfmania, $3.40 in savings Surfmania, $3.40 in savings Surfmania, $5.60 in savings Surfmania, $5.60 in savings Coolwaves, $3.40 in savings Coolwaves, $3.40 in savings Final prices are the same. Final prices are the same.
Answer:
Surfmania, $3.40 in savings
Step-by-step explanation:
First, find the price with Surfmania:
170(0.7)
= 119
Find the price with Coolwaves now:
170(0.9)
= 153
153(0.8)
= 122.4
Now, find the amount in savings:
122.4 - 119
= 3.4
So, Surfmania has the better deal with $3.40 in savings.
$750 loan 7% a year three years of no payments how much interest are you paying?
Answer:
$157.50
Step-by-step explanation:

I = 750 × 0.07 × 3 = 157.5
I = $ 157.50
The simple interest accumulated
on a principal of $ 750.00
at a rate of 7% per year

We have,
The number of hours driven by Kelly.
= 5/6 hours
The number of hours driven by Joshua.

= 13/30
Thus,
Kelly drove 13/30 hours longer.
