Answer:
x=7
Step-by-step explanation:
CD=DA
5X-6=3X+8
5X-3X=8+6
2X=14
X=7
57-10.51=46.49
46.49-8.73=37.76
37.76-8.47=29.29
Therefore Daniel has $29.29 left.
Answer:
d) 86.2 degrees
x = 86.20°
Attached is the image used in the question;
Step-by-step explanation:
Applying the law of cosine;
Cos C = (a² + b² - c²)/2ab
Where;
Angle C = x
c = 13 ft
b = 9ft
a = 10ft
Substituting into the equation;
Cos x = (10² + 9² - 13²)/(2×10×9)
Cos x = 0.0667
x = cos⁻¹(0.0667)
x = 86.20°
Answer:
Step-by-step explanation:
4.2x+4.7=18.6
Multiple each term by 10
42x + 47 = 186
Collecting like terms
42x = 186 - 47
42x = 139
x = 139/42
x = 3 13/42 or 3.3
Answer:
Below.
Step-by-step explanation:
-5/8 * 1/3 = -5/24
-5/12 * 1/2 = -5/24
-5/6 * 1/4 = -5/24.
