Step-by-step explanation:

Step 1: Simplify

$4+9x^2/3 - 1$

$=4+3x^2+-1$

Step 2: Combine Like Terms:

$= 4+3x^2+1-1$

$= (3x^2)+(4+-1)$

Answer: $= 3x^2+3$

Explanation in words (Short Form)

- The first step is to use the formula and simplify it. So first we will Rewrite the division as a fraction.

- The second step is to Cancel the common factor of 9 and 3. Then Factor 3 out of 3. After that Cancel the common factor.

- The third step is to divide $3x^2$ by 1. Then at the end, subtract 1 from 4. The answer will result as $3x^2+3$

Answer:

$=3x^2+3$

Hope this helps.

Answer:

$\frac{16}{195}$

Step-by-step explanation:

To obtain the result of a fractions multiplication we need to multiply both numerators and the divide by the multiplication of the denomitators. In general, given a,b,c,d real numbers with b and d not zero, we have that

$\frac{a}{b}*\frac{c}{d}=\frac{a*c}{b*d}$

Substituting a,b,c and d for 8,15,2 and 13 we obtain that

$\frac{8}{15}* \frac{2}{13} =\frac{16}{195}$

The balance of a loan is $2,570 in January, and the monthly payment is $125.50. The relationship between the loan balance, y, an

Hoochie [10]

1600<2570-125.5x<2000 subtract 2570 from all terms...

-970<-125.5x<-570 divide all terms by -125.5 (and reverse signs because of division by a negative!)

7.73>x>4.54 and x is months since January, and since months can only be integers...

x=[5,7]

So January + 5, 6, and 7 respectively are the three months that satisfy the equation...

June, July, and August.

Solve the equation 0.2(d-6)=0.3d+5-3+0.1d for d

WINSTONCH [101]

Answer:

d= -16

Step-by-step explanation:

To answer this question you'll have to first simplify the equation to

0.2d+-1.2=0.3d+5-3+0.1d

then combining like terms you get

0.2d-1.2=(0.3d+0.1d)+(5+-3)

0.2d-1.2=0.4d+2

then subtract 0.4d from both sides leaving you with

-0.2d-1.2=2

then add 1.2 to both sides

-0.2d=3.2

after you divide both sides by -0.2

leaving you with the answer

D= -16

Which is largest 3.3 times 10^5 or 3.1 times 10^5

erik [133]

Answer: 3.3 times 10^5 is bigger

Step-by-step explanation: 10^5= 10*10*10*10*10=100,000.

so 100,000 multiplied by 3.3 = 330,000

or 3.1 multiplied by 100,000 = 310,000 so it's obvious that 330,000 is bigger.
