Answer:
4
Step-by-step explanation:
We can see that 9 households are represented in the data, 4 of them are zeros. This means 4 households in Cam's neighborhood have 0 children.
Started at 2000....after 6 hrs it grew to 2400...that means in 6 hrs, it grew 400.
6/400 = 16/x ....6 hrs to 400 = 16 hrs to x
this is a proportion, so we cross multiply
(6)(x) = (400)(16)
6x = 6400
x = 6400/6
x = 1066.67 <==
Answer:
x = -3
y = 6
z = -5
Step-by-step explanation:
A) x + y + 2z = -7
B) -5z = 25
C) 3x - 3y - 6z = 3
B) -5z = 25
z = 25/-5
(z = -5)
A) x + y + 2(-5) = -7
x + y = -7 + 10
x + y = 3
(x = 3 - y)
C) 3x - 3y + 6(-5) = 3
3x - 3y + 30 = 3
3x - 3y = -30-3
3x - 3y = - 27
C) 3 (3-y) - 3y + 30 = 3
9 - 3y - 3y+ 30 = 3
-6y + 39 = 3
-6y = -39 + 3
y = -36/-6
(y = 6)
x + 6 = 3
x = 3 -6
(x = -3)
Answer:

Step-by-step explanation:
Amount if retired at 66 = $2460/mo
Less 25 % = 0.25 × 2460 = <u> -615
</u>
Amount if retired at 62 = $1845/mo
John would receive
