Mathematics

Dafna1 [17]4 years ago

Answer: -45, -43, -41, -39

Step-by-step explanation:

The four consecutive odd numbers are

x, (x + 2) , (x + 4) + (x + 6)

Therefore their sum

x + x + 2 + x + 4 + x + 6 = -168

                         4x + 12 = -168

                               4x  = -168 - 12

                               4x  = - 180

Divide by 4                x = - ¹⁸⁰/₄

                                  x  = -45

Now to determine the consecutive odd integers , we put the values in the above algebraic expression.

x, (x + 2), (x + 4), (x + 6) = -45, (-45 + 2), (-45 + 4), (-45 + 6)

                                     = -45 , -43, -41, -39

The numbers of cars (c) in the parking lot increases when the parking fee (f) decrease. Write the correct equation for this scen
vodka [1.7K]
So when one goes up, the other goes down. This is an inverse equation.

An inverse equation looks like this: y = 1/x

In this case, when parking fee (f) decreases, cars (c) increase.
You know which side to put each variable on using the chart they gave you.
f         | c
20.00  15        (20.00 = x/15) x=300
30.00  10        (30.00 = x/10) x=300

So your equation in this case is f = 300/c
Knowing that, plug in the fee of 6.00

6 = 300/c   Multiply both sides by c.
6c = 300    Divide both sides by 6.
c = 50 cars

0.2(10-5c)=5c-16 halp
iogann1982 [59]

Answer:

c= 3

Step-by-step explanation:

0.2(10 -5c)= 5c -16

<em>Expand</em><em>:</em>

0.2(10) +0.2(-5c)= 5c -16

2 -c= 5c -16

<em>Bring</em><em> </em><em>all</em><em> </em><em>c</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em>,</em><em> </em><em>constant</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>other</em><em>:</em>

5c +c= 2 +16

<em>Simplify</em><em>:</em>

6c= 18

<em>Divide</em><em> </em><em>by</em><em> </em><em>6</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

c= 18 ÷6

c= 3
