Mathematics
1 answer:
PSYCHO15rus [73]3 years ago
8 0

Answer:

Step-by-step explanation:

3)\frac{5x}{2}+125 = 180\\\\\frac{5x}{2}=180-125\\\\\frac{5x}{2}=55\\\\        5x    = 55*2\\\\          x    =\frac{55*2}{5}\\\\         x = 11*2 = 22

4) 3x+ 42 + 90= 180

3x + 132 = 180

        3x = 180 -132

        3x = 48

          x = 48/3

         x = 16

Find the balance in an account with $7,000 principal earning 5% interest compounded quarterly
nadya68 [22]

Answer:

The balance is \$11,505.34  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=10\ years\\ P=\$7,000\\ r=0.05\\n=4  

substitute in the formula above  

A=\$7,000(1+\frac{0.05}{4})^{4*10}=\$11,505.34

Solve for h<br><br> can someone please answer and explain thank you &lt;33
Oxana [17]

Answer: h=\frac{2A}{(a+b)}

Step-by-step explanation:

To solve for h, we want to get h alone. We need to use our algebraic properties.

A=\frac{1}{2} h(a+b)                             [multiply both sides by 2]

2A=h(a+b)                              [divide both sides by (a+b)]

h=\frac{2A}{(a+b)}

Now that we have h alone, we know that h=\frac{2A}{(a+b)}.

On monday ,jan made wgitmddrawls of $25,$45 and $75 from her savings account .On the sane day, het twin sister lola made withdra
Dafna11 [192]
Part (a):
We will assume that the total amount is Jan's saving account is "m"
Now, "withdrawal" means that she took money from her account, which means that the amount of money in her account decreased by the amount she withdrew.
Sum of negative integers to show her withdrawals = -25$ - 45$ - 75$
Amount of money remaining in her account = m - 145$
The amount of money Jan withdrew = 25$ + 45$ + 75$ = 145$

Part (b):
We will assume that the total amount is Lola's saving account is "n"
Now, "withdrawal" means that she took money from her account, which means that the amount of money in her account decreased by the amount she withdrew.
Sum of negative integers to show her withdrawals = -35$ - 55$ - 65$
Amount of money remaining in her account = n - 155$
The amount of money Lola withdrew = 35$ + 55$ + 65$ = 155$
