Answer:
2) x = 2
3) x = 40
Step-by-step explanation:
Complementary angles add up to 90° and supplementary angles add up to 180°
2) 7x + (34x + 8) = 90°
(2x - 9) + (3x - 11) = 180°
<h3>
Answer: 4 people</h3>
Work Shown:
2/5 = 0.4
(10 people)/(1 hour) = (x number of people)/(0.4 of an hour)
10/1 = x/0.4
10*0.4 = 1*x
4 = x
x = 4
She can check out 4 people in 2/5 of an hour.
Note: 2/5 of an hour = (2/5)*60 = 24 minutes
Answer:
d. 70
Step-by-step explanation:
Substituting the value of x=-4, in the given quadratic expression,
3* (-4)^2 - 5*(-4) + 2
= 3*16 - (-20) + 2
= 48 + 20 + 2
= 70
Yes it is proportional for a table
