Answer:
13
Step-by-step explanation:
to find the length between two point you've got to use the formula
√(x2-x1)^2 +(y2-y1)^2
√(-2-3)^2 + (-4-8)^2
√(-5)^2 + (-12)^2
√ 25+144
√169
13
520*.04=20.8, or closer to 21 spam emails.
T=16x+96 so if he wants to receive 130$ a day he must work at least 3 hours of over time.
X/6 >= 9
x >= 6 x 9
x >= 54
Therefore, 60, 72 and 54 satisfies the inequality.
