Answer:

Step-by-step explanation:

Sam bought a chocolate. He ate some and leaving 0.75 for Alice.

Alice ate 18.50 grams of chocolate and return the rest to Sam, which was 65% of the original chocolate.  How much chocolate did Sam had at the beginning?

Now solve the equation:

0.75x - 18.50 = 0.65x

Combine the like terms:

0.75-0.65x = 18.50

0.1x= 18.50

x = 18.50/0.1

x=185

This shows that Sam had 185 grams of chocolate...

Vika [28.1K]

The solution would be like this for this specific problem:

 

a + 20 = 5/7 (3a - 20) <span>
a + 20 = (15a - 100)/7 </span><span>
Multiply both side by 7, </span><span>
7a + 140 = 15a - 100 </span><span>
8a = 240<span> 
</span></span>a = 30

3a = 90

a + 20 = 50

3a - 20 = 70

<span>5/7 x 70 = 50</span>

Ben used 10 1/2 gallons to drive 4 3/4 hours. How many gallons did Ben use in 1 hour?
Kryger [21]

Answer:

About 2.2 gallons

Step-by-step explanation:

Create the following proportion:

\frac{10.5}{4.75} = \frac{x}{1}

Cross multiply.

10.5 x 1 = 10.5

4.75 x X = 4.75x

4.75x = 10.5

Divide both sides by 4.75x.

10.5/4.75 = 2.2

What fraction represents 0.1875 ft?
aliya0001 [1]

Answer:

There is not much that can be done to figure out how to write 0.1875 as a fraction, except to literally use what the decimal portion of your number, the .1875 , means. Since there are 5 digits in 1875 , the very last digit is the "100000th" decimal place. So we can just say that .1875 is the same as 1875/100000.

Answer:

  48

Step-by-step explanation:

Evaluate each of the functions by putting the number where x is.

  g(x)=x^2-4\\\\g(-7)=(-7)^2-4=49-4\\\\\boxed{g(-7)=45}\\\\f(x)=x+4\\\\f(-7)=-7+4\\\\\boxed{f(-7)=-3}

Then the difference is ...

  g(-7) -f(-7) = 45 -(-3) = 45 +3 = 48
