-32= 4c -12   
-32+12= 4c     Isolated 4c
4c= -20           Collected like terms
c= -20/4          Divided both sides by 4

Can someone please help me with this question
zlopas [31]

Answer:

15 kilometers

Step-by-step explanation:

So we know:

For 4 days she runs 1500 meters each day.

For 3 days she runs 3 kilometers each day.

First off, lets convert 1500 meters into kilometers.

There are 1000 meters in a kilometer, so pluggin in 1500 meters:

1500/1000 = 1.5

So for 4 days she runs 1.5 kilometers each day.

Now, to find the total kilometers, we must find multiply the 1.5 kilometers by the 4 days, the 3 kilometers by the 3 days, then add those two together.

So lets do this:

1.5*4 = 6

So she ran 6 kilometers in the first 4 days.

Next we have:

3*3 = 9

So she ran 9 kilometers in the last 3 days.

Now finally add them together:

6 + 9 = 15

So she ran a total of 15 kilometers.

Hope this helps!

Answer:

Part A) The percentage increase was 6.1\%

Part B) Michael is financially better off this year than last year

Step-by-step explanation:

Part A)

we know that

Using proportion

Let

x-----> the percentage increase

\frac{100\%}{33,000}=\frac{x\%}{35,000-33,000}\\ \\x=2,000*100\%/33,000\\ \\x=6.1\%

Part B) Compare the percentage increase with the inflation

6.1\%>5\%

The percentage increase is greater than the inflation

therefore

Michael is financially better off this year than last year

99. What is the greatest prime factor of 5,355?<br> A. 17<br> B. 51<br> C. 119<br> D. 131<br> E. 153
NemiM [27]
Hello,

5355 is divisble by 3 since 5+3+5+5=18 is divisible by 3
5355=3*1785
1785 is divisble by 3 since 1+7+8+5=21 is divisible by 3
1785=3*595
595 is not divisible by 3 but by 5
595=5*119
119 is divisible by 7 since 1*2+1*3+9*1=14 is divisible by 7.
119=7*17

17 is prime
Answer A

13. Let A = the amount of money in the given time, P = principal amount; the amount of money you start with, T = time in years, R = interest rate, and N = amount of times interest is compounded each year.

The formula for compound interest is:

A = P(1 +  \frac{R}{N} )^{NT}

Now, we find in the information from the description needed to plug in. P = $1000, R = 7% or 0.07, N = 1 time a year, T = 3 years

A = 1000(1 +  \frac{0.07}{1})^{1(3)}

This simplifies to:

A = 1000(1 + 0.07)^{3}

And again to:

A = 1000(1.07)^{3}

Plug this into a calculator:

A = 1225.043 or ≈1,225.04

14. (x² + 3)(x - 3)(x + 3)

I'm going to do FOIL method on the second and third binomials first and simplify. This gives you:

(x² + 3)(x² - 9)

Then you do the FOIL method again to get:

x⁴ - 9x² + 3x² - 27

And combine like terms for your answer:

x⁴ - 6x² - 27

Number 15 doesn't give you a number to set the polynomial (that results from multiplying those two binomials) equal to so I'm guessing it wants you to set said polynomial equal to zero and solve for x then plug back in. 

If not, your area is found by the equation 3x² - 5x - 12
