Step-by-step explanation:
GIven data
Amount to be save= $175
Weekly allowance = $14
Hence the number of weeks it will take to save $175 is given as
=175/14
=12.5

Answer:
The population at the end of 2017 is 65,550
Step-by-step explanation:
step 1; find the population at the end of 2016
if 60,000 increases by 15% therefore final % = 100 +15 =115%
Therefore 60,000 = 100%
? = 115%
<em>by cross multiplication</em>
={ (115 % x 60,000) /100} =69,000
Step 2: find the population at the end of 2017
if 69,000 decrease by 5% therefore the final% = 100 -5 =95%
Therefore 69000 = 100%
? = 95%
by cross multiplication
= 69000 x 95/100 = 65,550
we are given
1.11, 2.54, 3.97, 5.40, ...
we can see that
first term is 1.11
now, we can find common difference
now, we can find second difference
we can see that
differences are same
so, this is arithematic sequence
now, we can find it's nth term
now, we can simplify it
and we get

Answer:
1. x = 6/-2b
2. x = -1
Step-by-step explanation:
X in terms of b just means solve for x but you don't have a specific number because one isn't given for b.
-2(bx - 5) = 16
-2bx + 10 = 16
-2bx + 10 - 10 = 16 - 10
-2bx = 6
-2bx/-2b = 6/-2b
x = 6/-2b
To find x when b = 3, just plug in 3 for b.
x = 6/-2(3)
x = 6/-6
x = -1
