Since the left side of the equation says f(5), then plug in 5 for x.

So, it is:

-4|5| + 3
= -20 + 3
= 23

My sister can walk from school to home in 35 minutes. I can walk from school to home in 20 minutes. But today I stayed for some

Verizon [17]

Answer:

you both will reach the home at the same time.

I) You can catch your sister.

ii) Reason: you both will reach home at the same time.

Step-by-step explanation:

Let "d" be distance from school to home.

Let's find the speed of you and your sister.

Speed = $\frac{Distance}{Time}$

Your speed = $\frac{d}{20}$

Your sister's speed = $\frac{d}{35}$

Today, You stayed for some extra help by the time your sister covered $\frac{3}{7}$ of the way home.

Remaining distance to reach the home = $1 - \frac{3}{7}d = \frac{7-3}{7}d = \frac{4}{7}d$

Now let's find the time to be taken your sister to reach the home.

Time = $\frac{distance}{speed}$

= $\frac{\frac{4}{7}d }{\frac{1}{35} d} = \frac{4}{7} *\frac{35}{1} = 20$

So, your sister will take 20 minutes to get home by the time your start.

We know that it takes you 20 minutes to reach your home.

Therefore, you both will reach the home at the same time.

I) You can catch your sister.

ii) Reason: you both will reach home at the same time.

3 times what equal 19?

MissTica

Answer:

6 1/3

Step-by-step explanation:

3 times what equals 19 can be in the form of an equation as shown below. It shows that the value we are finding for is unknown, therefore it is a variable. A variable is the unknown value in an equation.

Equation: 3x = 19

With the equation in hand, we can now solve the problem easily.

3x = 19

Carry the 3 to the 19(Carry over the like terms across leaving the variable or the unknown)

x = 19÷3

x = 6.33333 or 6 1/3

To check if the answer was correct:

3 × 6 1/3 = 19

You regain the answer <em>19</em>

Pleaseeee answer correctly <br> Will mark Brianliest !!! HELP !

Paha777 [63]

Answer: 11

The code would print 11 as x=x-4 basically sets x to what x was and subtracts it by 4 which means 15 was its previous value and it takes 4 away from it so it is now 11. Then because the loop condition is x=11 the loop condition has been met and will now go and display x.
