Answer:
153
Step-by-step explanation:
<u><em>Box 1:</em></u>
180 = 124 + (5x + 11)
56 = 5x + 11
45 = 5x
x = 9
<em><u>Box 2:</u></em>
RT = QS
x + 9 = 2x - 5
x = 14
<u><em>Box 3: </em></u>
14x - 3 = 18x -19
16 = 4x
x = 4
<em><u>Box 4:</u></em>
180 = (9x - 8) + (7x - 4)
180 = 16x - 12
192 = 16x
x = 12
<em><u>Box 5:</u></em>
(6x + 34) = (12x - 8)
42 = 6x
x = 7
<em><u>Box 6:</u></em>
45 = 7x - 25
70 = 7x
x = 10
<em><u>Box 7: </u></em>
54 - x = 3x - 10
64 = 4x
x = 16
<u><em>Box 8:</em></u>
12x + 1 = 9x + 16
3x = 15
x = 5
<u><em>Box 9:</em></u>
3x + 2x - 5 = 90
5x - 5 = 90
5x = 85
x = 17
Final Code:
(9)(17) = 153
Answer:
The perimeter of △DEF 43
Step-by-step explanation:
Sin A/ a = Sin B / b = Sin C/ c
sin D/ d =
Sin E / e = sin F /f
sin 52/ e = sin 90 / 18
e = 18 x sin 52 / sin 90
e = 14.184 /1
e = 14.2
From phythagoras theorem ,
/hyp/² = /opp/² + /adj/²
18² = 14.2² + /adj/²
/adj/²= 18² - 14.2²
/adj/² = 324 + 201.64
/adj/² = 119.51
/adj/ = √122.36
= 11.1
Perimeter of Triangle = a + b +c
where a = side
b = base
c = side
Perimeter = 18 + 11.1 + 14.2
Perimeter = 43.3
Perimeter= 43

Step-by-step explanation:
Answer:
Aaliyah bought 3c and Mari bought 3
Step-by-step explanation:
Maria - 3 chocolates consider as variable Y
Aaliyah bought c times as Maria
