What is the first step to solving this algebraic equation?
-5c + 6 = -4

Answer:

x= -3

Step-by-step explanation:

f(x)=0 when x= -3

Answer:

X=1

Step-by-step explanation:

If you look at the graph you can see that it intercepts 1 on the X axis so that would be the coordinates (1,0)..and f(x) would be the y and that equals 0.

Answer: C.  [tex]26.2\div1\dfrac{31}{100}[/tex]

Step-by-step explanation:

Given:  A marathon is 26.2 miles long.

There is a water station every[tex]1\dfrac{31}{100}[/tex] miles along the race route.

Total number of water stations = (marathon distance) ÷ (distance between any two water stations)

The expression represents the total number of water stations[tex]=26.2\div1\dfrac{31}{100}[/tex]

Hence, the correct option is C.

He can wrap 6 gifts using the spool of ribbon

Step-by-step explanation:

Here, we want to know the number of gifts of the same dimension that Franklin can wrap using the spool of ribbon

Per gift 1.25m of ribbon is needed

Now in the spool, there is 25 feet of ribbon

1 m = 3 feet

x m = 25 feet

x = 25/3 meter

so the number of gifts of the same dimension he can wrap using the spool of ribbon will be;

25/3/1.25 = 25/3.75 = 6.67

Since he cannot wrap a gift fractionally, the number of gifts he can wrap is thus 6

Answer:

A: days: 2 and rental cost: 480

B: y=60x

Step-by-step explanation:

The daily rental cost is 60 dollars, because 180/3=60 and 300/5=60. Now you can say that y(rental cost) = 60x(daily cost times x(days).

Step-by-step explanation:

I'm not sure but it might be because, while not in a vapor state yet, the molecules are moving faster as they get hotter and are getting closer to being a gas.  Because they aren't vibrating in place anymore, they will need more room to more around.  Again, I'm not positive but I think that this might work.

x < -2 means that x is any number that is less than -2.

Is -2 less than -2? Answer: No.

A number is equal to itself. A number is not greater than itself or less than itself.

When the solution to an inequality is x < -2, the only values of x that are valid are numbers less than -2. -2 itself is not a valid solution.

Can I have brainliest?

Answer:

8.7cm

Step-by-step explanation:

From the question, we know that:

10 km = 2 cm(on the map)

43.5 km = x cm

Cross Multiply

10 × x cm = 43.5km × 2

x cm = 43.5 km × 2/10

x cm = 8.7 cm

The length in centimetres of Galveston Island on Quincy's map is 8.7cm

Layla takes 32 minutes to ride 8-mile long trail.

Given Last week, Layla took 24 minutes to ride a trail that is 6 miles long.

So Speed of Layla to cover 6 miles is , [tex]\frac{6}{24} =0.25[/tex] miles per minute.

Now, Layla kept same speed of 0.25 miles per minute to rode 8-mile trail.

So, Time taken by Layla to cover 8 miles is [tex]\frac{distance}{speed}[/tex][tex]=\frac{8}{0.25} = 32[/tex] minutes.

Hence Layla takes 32 minutes to ride 8-mile long trail.

Answer:

50 new fish in total

so lets say 25 per month

Rate: 25 fish per month

Step-by-step explanation:

The rate is the population increasing is  0.135 or 13.5% .

Growth rates refer to the percentage change of a specific variable within a specific time period.

Growth rate= [tex]\frac{Present value - Past value}{Past value}[/tex]

According to the question

The population of fish increased from 370 to 420

i.e

Present value = 420

Past value = 370

over the months of March and April

By using Growth rate formula :

Growth rate= [tex]\frac{Present value - Past value}{Past value}[/tex]

Now,

Substituting values in formula

Growth rate= [tex]\frac{420 - 370}{370}[/tex]  

                    = [tex]\frac{50}{370}[/tex]

                    = 0.135 or 13.5%

Hence, the rate is the population increasing is  0.135 or 13.5% .
