10. b - 16.6 = -3.7.....add 16.6 to both sides
b - 16.6 + 16.6 = -3.7 + 16.6
b = -3.7 + 16.6
b = 12.9
14. 18.91 = -7.9 + x.....add 7.9 to both sides
18.91 + 7.9 = -7.9 + 7.9 + x
26.81 = x
16. 295.8997 = -10.1k....divide both sides by -10.1
295.8997 / -10.1 = (-10.1/-10.1)k
- 29.297 = k
18. -94.4724 = 3.3x....divide both sides by 3.3
- 94.4724 / 3.3 = (3.3 / 3.3)x
- 28.628 = x
20. -29.4x = -148.764...divide both sides by -29.4
(-29.4 / -29.4)x = - 148.764 / -29.4
x = 5.06

Step-by-step explanation:

Answer:
The perimeter is 56mm
Step-by-step explanation:
N/B: the figure is not given, nevertheless we can infer that the figure is a triangular figure given that the lengths provided is just three.
So the perimeter is the distance around the object.
Perimeter =20+20+16= 56mm
Step-by-step explanation:
x = $5
y = $1
4x + 10y = $30
4(5) + 10(1) = 30
$20 + $10 = $30
5x + 5y = $30
5(5) + 5(1) = 30
$25 + $5 = $30
<span>3^3 ÷ 9 / 11 - 2^2
=27 </span>÷ 9 / 11 - 4
= 27 * 11/9 -4
= 297/9 - 4
=33-4
=29
