P = 5 .............................................
this is how=
first you expand the second equation
<span>25 + 4p = -18 + -12 + 6p + 9p
</span>
then you add the like terms in the second equation:
25 + 4p = -30 + 15p
then this is how=
25+30 = 15p -4p
55=11p
p= 5
Um b is maybe 9n + 5 = 15n
um c is maybe 3 - 5 to the third power =3 - 125 = -122 + 7 = -115
maybe you have to add the positive 15n to -115 = -100n
um d is maybe 3b + 2c - 10c = 3b + -8c = -5 <span />
Okay, Jackie starts with 350 mailboxes, but has delivered to 150, so she only has to deliver to 200 more. She can deliver to 50 mailboxes per hour. So 200/50 = 4. The answer is 4 hours.
Number of swings = x
Number of slides = y
First condition:
number of slides must be more than 3 times number of swings
This means that: y > 3x
Second condition:
each swing cost 275$ and each slide costs 168$. They cannot spend more than 1250$. This means that the sum of costs of swings and slides should not exceed 1250$ (should be less than or equal to 1250$)
This means that: <span>275x+168y ≤ 1250
Based on this:
The correct choices are: b and d</span>
Answer:
Therefore,
The height is 23.3 ft.
Step-by-step explanation:
Given:
ΔABC ~ ΔXYZ
AC = 108.5 ft
BC = h
XZ = 14 ft
YZ = 3ft
To Find:
h = ?
Solution:
Δ ABC ~ Δ XYZ….Given
If two triangles are similar then their sides are in proportion.
Substituting the values we get
(nearest tenth)
Therefore,
The height is 23.3 ft.
