The right answer would be c. I can confirm it's c.4 because I received 100% on the test.
Answer:
150
Step-by-step explanation:
We perform addition.
a) The total of 48 added to itself
= 48 + 48 = 96
b) Its half plus half of the half
= 96 + (1/2 × 48) + (1/2 × (1/2 × 48)
= 96 + 24 + (1/2 × 24)
= 96 + 24 + 12
= 132
c) plus 18
= 132 + 18
= 150
Thus, adding 48 to itself, its half, and half of that to 18 results in 150.
Response: the equations are
0.02x + 0.07y = 156
y = 300 + x
Step-by-step explanation:
Let x denote the dollar amount from phone sales made by Josiah.
Let y indicate the dollar amount from his computer sales.
Josiah receives a 2% commission on his phone sales total and 7% on his computer sales. He accumulated a total of $156 in commission, leading to the equation
0.02x + 0.07y = 156 - - - - - - - - - - -1
Furthermore, it’s given that Josiah had $300 more in computer sales than in phone sales, expressed as
y = 300 + x
If these angles are complementary, their total adds up to 180°.
∠7=115°
∠7+∠2=180°
substituting the known values
115+∠2=180
deduct 115 from both sides
65°=∠2
Final answer=65°
