Remy walked to a friend’s house m miles away at an average rate of 4 mph. The m-mile walk home was at only 3 mph, however. Express as a fraction
a) Time Remy spent walking home.
b)Time Remy spent walking.

(Answer both (a) and (b).

Answers

Answer 1

Answer:

a) m/4 miles per hour

b) 7m/12 miles per hour

Step-by-step explanation:

Mathematically, at any point in time;

Time = distance/speed

The distance here at any point is m mph

a) For the time spent walking home

Time = m/4 miles per hour

b) We add the time walking to the friend’s house and the time that it took to walk home

That would be;

m/4 + m/3 = 7m/12 miles per hour

Given that f(x) = 4x - 7 and g(x) = 4x, find a simplified expression for
f(f(x)).

Answers

Given:

[tex]f(x)=4x-7[/tex]

[tex]g(x)=4x[/tex]

To find:

The expression for f(f(x)).

Solution:

We need to find f(f(x)).

[tex]f(f(x))=f(4x-7)[/tex]                             [tex][\because f(x)=4x-7][/tex]

[tex]f(f(x))=4(4x-7)-7[/tex]                             [tex][\because f(x)=4x-7][/tex]

Using distributive property, we get

[tex]f(f(x))=4(4x)+4(-7)-7[/tex]

[tex]f(f(x))=16x-28-7[/tex]

[tex]f(f(x))=16x-35[/tex]

Therefore, the expression for f(f(x)) is [tex]f(f(x))=16x-35[/tex].

What is the difference between –11x – 2 and 13x + 5?
24x + 7
-24x + 7
24x + 3
-24x - 7

Answers

Answer:[tex]\boxed{-24x-7}[/tex]Solution Steps:

____________________________

1.) Find the opposite of 13x + 5:To find the opposite of 13x+5, find the opposite of each term.[tex]13x=-13x[/tex][tex]5=-5[/tex]

 - We do this because when solving this they are in parenthesis, so you must get rid of the parenthesis by turning them negative.

Equation at the end of Step 1:

[tex]-11x-2-13x-5[/tex]2.) Combine −11x and −13x:[tex]-11x+-13x=-24x[/tex]

 - We do this since we can only have on variable at the end of the problem, so you just combine them if they have the same variable base.

Equation at the end of Step 2:

[tex]-24x-2-5[/tex]3.) Subtract 5 from −2:[tex]-2-5=-7[/tex]

 - We do this because we need one number left over to get a simplified version of this equation.

Equation at the end of Step 3:

[tex]-24x-7[/tex]

Melanie needs 5,000 chocolates for an event so far she has brought 2 cases of 1,125 chocolates each how many more does she need

Answers

Answer:

2750 chocolates

Step-by-step explanation:

Find how much she has bought already:

1,125(2)

= 2,250

Then, subtract this from 5,000

5000 - 2250

= 2750

So, she still needs 2750

Answer:

2,750

Step-by-step explanation:

2 cases of 1,125 chocolates = 2,250 chocolates

5,000 - 2,250 = 2,750 more chocolates needed

(that's also 3 cases of chocolates needed :p)

Yes, this is correct

WE can multiply 1*5 and 4*5 to get 5 to 20

19

Wrong

3 to 11, 1 to 3 isn't correct

For example, if we were to divide 3 by 3 to get one, 11/3 is 2. (6)

So, no

20

2/3 is 2 to 3

14/21 is 14 to 21

If we multiply 2*7 and 3*7, we get 14 to 21

21 25 to 30 is  equal to 35 to 42

The cellular connection buys new model Z-phones for $80 each and sells them for $200. What is the percent markup, n, for the model z-phone?

Answers

Answer:

250%

Step-by-step explanation:

Hi there!

In order to solve this problem, we have to divide 200 by 80.

When we do this, we get 2.5. The number in the ones spot, in this case 2, would be worth 200%.

Now we have the 0.5

A half is equivalent to 50%, so we add those two percentages together to get 250%.

Answers

Answer: Weight of sand in each bag = 3.17 lb.

Step-by-step explanation:

Given : Total weight of sand = 63.4 lb

Weight of sand in each small bag = ( 63.4) ÷ (20)

Weight of sand in each small bag = 3.17 lb

Hence, the weight of sand in each small bag = 3.17 lb.
