Answer:
2 small notebooks and 4 large notebooks
Step-by-step explanation:
$8 × 2 = $16
$10 × 4 = $40
2 + 4 = 6
$40 + $16 = $56
Hope that helps.
Answer and Step-by-step explanation:
To solve, we need to find how many miles are driven in an hour.
<u>Divide 132 by 3.</u>
132/3 = 44
<u>Now, we need to find how many hours it would take to drive 110 miles.</u>
<u>Cross multiply.</u>
<u />
<u />
<u>Divide by 44.</u>
<u />
<u />
<u />
<u>So, it would take 2.5 hours to drive 110 miles.</u>

2cos²x+cos x-1=0
cos x=t
2t²+t-1=0
t=[-1⁺₋√(-1+8)]/2=(-1⁺₋3)/4
We have two possible set solutions:
First set solutions.
t₁=(-1-3)/2=-4/4=-1
cos x=-1 ⇒x=cos⁻¹ (-1)=π +2kπ or 180º+360ºk (k=(...-2,-1,0,1,2...)
Second set solutions:
t₂=(-1+3)/4=2/4=1/2
cos x=1/2 ⇒ x=cos⁻¹ 1/2=π/3+2kπ U 5π/3+ 2kπ or
60º+360ºK U 300º+360ºK (k=...-2,-1,0,1,2,...)
solutions: first set solutions U second set solutions:
Answer in radians : π +2kπ U π/3+2kπ U 5π/3+ 2kπ (k=...-1,0,1,...)
Answer is degrees: 180º+360ºk U 60º+360ºK U 300º+360ºK (k=...-2,-1,0,1,2,...)

Answer:
S = 13 - x
T = (18 + x) / 2
Step-by-step explanation:
S = 18
T= 18
Sue gives away x, so subtract it from 18. But Tony gets x, so add it to 18 in his expression.
S = 18 - x
T= 18 + x
Sue eats 5 so subtract 5 from her expression. Tony eats half, so divide his expression by 2.
S = 18 - x - 5
T = 18 + x / 2
Simplify 18-5.
S = 13 - x
T = (18 + x) / 2
