Answer:

84 regular light bulbs

Step-by-step explanation:

When there are 7 regular light bulbs to every 1 energy saving one, there will be 7 more added for every 1 energy saving light bulb that there is. So if there is 12 energy saving light bulbs, just multiply 7 by 12 and you will get your answer.

An ostrich can run 25 miles in 40 minutes. How many minutes will it take the ostrich to run 40 miles if it runs at the same spee
fenix001 [56]

The Ostrich will take 64 minutes to cover 40 miles.

Data;

  • rate = 25 miles in 40 minute

<h3>Rate</h3>

To calculate the time it will take the ostrich to cover 40 miles, we have to compare it with the rate (speed).

25mi = 40 min\\40 mi = x min

Cross multiply both sides

x * 25 =40 * 40

simplify the value

x*25=40*40\\25x = 1600\\

divide both sides by the coefficient of x

25x = 1600\\25x/25 = 1600/25\\x = 64

From the calculations above, it would take the ostrich 64 minutes to cover 40 miles.

Find the slope-intercept form of the equation of the line that passes through
yawa3891 [41]

Answer:

Step-by-step explanation:

12x - 3y = 10

-3y = -12x + 10

y = 4x - 10/3....the slope here is 4

parallel lines will have the same slope

y = mx + b

slope(m) = 4

(-5,3)...x = -5 and y = 3

now we sub and find b, the y int

3 = 4(-5) + b

3 = -20 + b

3 + 20 = b

23 = b

so ur equation is : y = 4x + 23 <==
