Answer: $18.75
Step-by-step explanation:
1 - 3/8 = 5/8
12 x 5/8 = 7.5
7.5 x 2.5 = 18.75
Answer:
D. –5.2 + (–6.4) = –11.6
Step-by-step explanation:
First, you can eliminate A and C because 5.2 is positive. Since the red arrow is pointing left, it indicates that the number (-5.2) is negative.
Then, you look at the second arrow, the green one. It is pointing left, so it would be -6.4.
I hope this helps :)
When x=-4:
2(-4)+3y=4
3y=4+8
3y=12
y=4
So the ordered pair is (-4,4), I think
Answer: a = 81
Explanation:
Geometric mean: sqrt a • b
sqrt a • 15 = 9 sqrt 15
Sqrt 15a = 9 sqrt 15
(Sqrt 15a)^2 = (9 sqrt 15)^2
15a = 81 x 15
a = 81
