Answer:
is there a question in this? lol, if not, tyy!!
Step-by-step explanation:
1. use sin
inverse of sin(44/57) = 50.5 ---> 51°
2. use tan
inverse of tan(6/8) = 36.8 ---> 37°
3. use cos
inverse of cos(20/31) = 49.8 ---> 50°
4. use sin
inverse of sin(37/58) = 39.6 ---> 40°
A) S + D = 200
B) 85 S + 110 D = 18,250 we multiply A) by -85
A) -85 S -85 D = -17,000 then we add to B) and get
25 D = 1,150
Double Bed Rooms = 46
Single Bed Rooma = 154
*************************************************
Double Check
46 * 110 = 5,060 154 * 85 = 13,090
Total = 18,150
<span>2(b-5)+3(b-2)=8+7(b-4)
We simplify the equation to the form, which is simple to understand
<span>2(b-5)+3(b-2)=8+7(b-4)
Reorder the terms in parentheses
<span>+(+2b-10)+3*(b-2)=8+7*(b-4)
Remove unnecessary parentheses
<span>+2b-10+3+*(+b-2+)=+8+7+*(+b-4+)
Reorder the terms in parentheses
<span>+2b-10+(+3b-6)=8+7*(b-4)
Remove unnecessary parentheses
<span>+2b-10+3b-6=+8+7+*(+b-4+)
Reorder the terms in parentheses
<span>+2b-10+3b-6=8+(+7b-28)
Remove unnecessary parentheses
<span>+2b-10+3b-6=+8+7b-28
We move all terms containing b to the left and all other terms to the right.
<span>+2b+3b-7b=+8-28+10+6
We simplify left and right side of the equation.
<span><span>-2b=-4
</span>We divide both sides of the equation by -2 to get b.
<span>b=2</span></span></span></span></span></span></span></span></span></span></span>
