Solve the following equation: * -9 (t – 2) = 4(t – 15)

Mathematics

Answer:

6 =t

Step-by-step explanation:

-9 (t – 2) = 4(t – 15)

Distribute

-9t +18 = 4t -60

Add 9t to each side

-9t +18+9t  = 4t+9t -60

18 = 13t -60

Add 60 to each side

18+60 = 13t-60+60

78 = 13t

Divide each side by 13

78/13 = 13t/13

6 =t

Answer:

The interest rate of the account is 3\%

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=14\ years\\ P=\$1,863\\ A=\$2,830.97\\n=4  

substitute in the formula above  and solve for r

\$2,830.97=\$1,863(1+\frac{r}{4})^{4*14}  

(2,830.97/1,863)=(1+\frac{r}{4})^{56}  

(2,830.97/1,863)^{1/56}=(1+\frac{r}{4})

[(2,830.97/1,863)^{1/56}-1]=\frac{r}{4}    

r=4*[(2,830.97/1,863)^{1/56}-1]\\ \\r= 0.03

Convert to percent

r= 0.03*100=3\%

Tell whether the angles are adjacent or vertical. Then find the value of x.
krok68 [10]

Answer : The angles are vertical angles and the value of x is 25^o

Step-by-step explanation :

Adjacent angles : It is defined as the two angles that have the common arm and common vertex.

Vertical angles : It is defined as the two lines intersect each other and form angles. The opposite angles are known as vertically opposite angles.

And we know that the vertically opposite angles are equal.

In the given image, the angles are vertical angles and vertically opposite angles are equal.

So,

(4x-25)^o=75^o

4x-25^o=75^o

4x=75^o+25^o

4x=100^o

x=\frac{100^o}{4}

x=25^o

Therefore, the angles are vertical angles and the value of x is 25^o
