Answer:
16
Step-by-step explanation:
Given
4c + d and c = 5, d = - 4, then substitute values into the expression
= (4 × 5) + (- 4) = 20 - 4 = 16
Answer:
x° = 139
step 1 :
180 - (37 + 38)
= 180 - 75
= 105°
step 2 :
180 - 105
= 75°
step 3 :
180 - 116
= 64°
step 4 : this step to find the value of x
x° = 180° - (64 + 75)°
= 180° - 139°
= 41
x° = 41

Answer:
3
Step-by-step explanation:
2(x + 1) = 3(5 - x) + 2
Distribute,
2(x + 1) = 3(5 - x) + 2
2x + 2 = 3(5 - x) + 2
Rearrange terms,
2x + 2 = 3(5 - x) + 2
2x + 2 = 3(-x + 5) + 2
Distribute,
2x + 2 = 3(-x + 5) + 2
2x + 2 = -3x + 15 + 2
Add the numbers,
2x + 2 = -3x + 15 + 2
2x + 2 = -3x + 17
Subtract 2 from both sides,
2x + 2 = -3x + 17
2x + 2 - 2 = -3x + 17 - 2
2x = -3x + 17 - 2
2x = -3x + 15
Add 3x to both sides,
2x = -3x + 15
2x + 3x = -3x + 3x + 15
5x = -3x + 3x + 15
5x = 15
Divide both sides by the same factor (15),
5x = 15
5x/5 = 15/5
x = 15/5
x = 3
Hence, the answer is 3.
