Answer:x=12 and x=2

Step-by-step explanation:

2.2x-10=0.2x+14

2.2x-10-(0.2x+14)=0

2.2x-0.2x-14-10=0

2x-24=0

2x=24

x=24/2

x=12

-4x+5=x-5

-4x+5-(x-5)=0

-4x-x+5+5=0

-5x+10=0

-5x=-10

x=-10/-5

x=2

The amount of money Sharita makes varies directly with the number of hours she works. If she earns $41.25 for 5 hours of work, h
fgiga [73]
Let M be the amount she earns and H the hours worked;
M\alpha H
M=aH
Where a is a constant of proportionality;
Given that M=41.25 and H=5
41.25=5a
a=\frac{41.25}{5}
a=8.25
The equation then is;
M=8.25H
When she works 8 hours;
M=8.25*8
=66 dollars

The midpoint is the average of the endpoint coords.
If (x,y) is F, then -6=(-14+x)/2 and 7=(13+y)/2.
-14+x=-12 so x=2, and 14=13+y, so y=1 and F is (2,1).
so the answer is (2,1)

Mrs. Jackson put a total of $10,000 into two accounts one account earns 6% simple annual interest the other account earns 6.5% s
kozerog [31]

Answer:

The money invested in account at 6 % rate is $ 9230.77

The money invested in account at 6.5 % rate is $ 769.23

Step-by-step explanation:

Given as :

The total amount saves in two account = $ 10,000

The two rate of interest are 6 % and 6.5 % at simple interest

The interest earn at 6 % rate = $ 632

The interest earn at 6.5 % ate = $ 50

Now, Let The amount deposit at 6 % rate = $ x

And The amount deposit at 6.5 % rate = $ 10,000 - $ x

<u>From Simple Interest method</u>

Simple Interest = \dfrac{\textrm principal \times \textrm Rate\times \textrm time}{100}

or, At 6.5 % rate

$ 50 =  \dfrac{\textrm (10,000 - x ) \times \textrm 6.5\times \textrm 1}{100}

or, 10000 - x =  \frac{5000}{6.5}

Or, 10000 - x = 769.23

∴  x = 10000 - 769.23

I.e x = $ 9230.77

So , At 6.5 % the amount deposit = 10,000 - 9230.77 = $ 769.23

So, At 6 % The amount deposit  = $ 9230.77

Hence The money invested in account at 6 % rate is $ 9230.77

And  The money invested in account at 6.5 % rate is $ 769.23 Answer
