Answer:

The amount of time it takes Shelly to clean each house is 3.6 hours or 2 hours 36 minutes.

Step-by-step explanation:

Shelly cleans 5 different houses in 18 hours.

To compute the amount of times Shelly spends cleaning one house divide the total hours spend by the number of houses cleaned.

The number of hours it takes Shelly to clean a single house is:

Number of hours spent cleaning 1 house = \frac{18}{5}=3.6 hours.

Thus, the amount of time it takes Shelly to clean each house is 3.6 hours or 2 hours 36 minutes.

Solve the system of linear equations below.<br><br> y = -2x + 19<br> y = x + 7
ASHA 777 [7]
Hey there!

y = -2x + 19
y = x + 7

We gonna solve this system of equation by using the substitution method.

We wanna solve y = -2x + 19 for y

Let start by substitute -2x + 19 for y in y = x + 7

y = x + 7
-2x + 19 = x + 7

Subtract x from both sides

-2x + 19 - x = x + 7 - x

-3x + 19 = 7

Now subtract 19 on both sides

-3x + 19 - 19 = 7 - 19

-3x = -12

Then divide both sides by -3

-3x/-3 = -12/-3

x = 4

We have the value of x. Now we gonna use that same value to find the value for y.

We gonna do that by substitute 4 for x in y = -2x + 19

y = -2x + 19

y = -2(4) + 19

y = -8 + 19

y = 11

Thus,

The answer is: x = 4 and y = 11

Is 5 + 3x1 - x) equivalent to 8 – 8x?
nalin [4]

Answer:

no

Step-by-step explanation:

5+3x is equal to 8x.

if there is no number in front of a variable, it is understood to be a one. so 1-x would basically be 1-1. this cancels out the x, making it impossible for the equivalent equation to be 8 - 8x
