Answer:
Both sides are equal, true for all 'b'
Step-by-step explanation:
Add similar elements: b + 0.17b = 1.17b
1.17b = 1.17b
Multiply both sides by 100
1.17b * 100 = 1.17b * 100
Refine
117b = 177b
Subtract 117b from both sides
117b - 117b = 117b - 117b
Refine
0 = 0
Both sides are equal, true for all 'b'

Answer:
17) 288
18) $69.30
19) $56.00
20) $135.00
21) $132.00
22) $4,515
23) 6.9%
Step-by-step explanation:
17)(3 × 4) × (6 × 4) = 288
18) 18% + 8% + 100% = 126%.
$55 × 1.6 = $69.3
19) $32 × 175% = $56
20) 100% - 15% - 10% = 75%
$180 × 0.75 = $135
21) $3,300 × 0.04 = $13
22) 2.5% × 3 = 7.5%
$4,200 × 1.075 = $4,515
23) 58 × 1.069 = 62.002
X= unknown variable (original tuition cost)
12% of x=$138
can also be written as
0.12x=$138
Divide both sides by 0.12 to isolate x
x=138/0.12
x= 1150
Answer:
![tan A=\frac{8}{15}](https://tex.z-dn.net/?f=tan%20A%3D%5Cfrac%7B8%7D%7B15%7D)
Step-by-step explanation:
According to the trigonometric ratios the tangent of an angle is the ratio of perpendicular to base, i.e.
![tan\theta=\frac{Perpendicular}{Base}](https://tex.z-dn.net/?f=tan%5Ctheta%3D%5Cfrac%7BPerpendicular%7D%7BBase%7D)
In the provided triangle the perpendicular is 8 and base is 15.
Compute value of tan <em>A</em> as follows:
![tan\theta=\frac{Perpendicular}{Base}\\tanA=\frac{8}{15}\\](https://tex.z-dn.net/?f=tan%5Ctheta%3D%5Cfrac%7BPerpendicular%7D%7BBase%7D%5C%5CtanA%3D%5Cfrac%7B8%7D%7B15%7D%5C%5C)
Thus, the value of tan <em>A</em> is
