Answer:
3/5 is the number that can be distributed across two terms inside parentheses.
you might not need it but:
x = 5
Step-by-step explanation:
<u>3/5(x - 10)</u> = 18 - 4x - 1
using distributive property, open the parentheses:
<u>3/5x - 6 </u>= 18 - 4x - 1
Simplify:
3/5x + 4x = 17 + 6
4⅗x = 23
x = 5
Cost of the 3 shirts before tax = 2*49.96 + 1/2 * 49.96
= $124.90
After adding 7.1% tax total cost = 124.90 * 1.071 = $133.77
So the cost od each shirt = 133.77 / 3 = $44.59 (answer)
Answer:
We have sinθ = 12/13
The method here is to figure out the value of θ
Using a calculator sin^(-1)(12/13) =67.38°
67.38° is in quadrant 1 so we must substract 67.38° from 180° wich is π
- 180-67.38= 112.61° ⇒ θ= 112.61°
Now time to calculate cos2θ and cosθ using a calculator
- cosθ = -5/13
- cos2θ = -0.7
The values we got make sense since θ is in quadrant 2 and 2θ in quadrant 3
