Answer:

You can tell if two fractions are proportional by using cross multiplication. Only equivalent fractions are proportional. To do this, multiply the denominator, the bottom number in the fraction, of the first fraction with the numerator, the top number in the fraction.

Step-by-step explanation:

If you get 1 dollar every 2 week how many weeks will it take to get 800 dollars
ipn [44]

Step 1 ) Apply numbers into fraction form. Include variables to represent numerator and denominator.

\displaystyle\frac{2w}{1d}

Note: w = week; d = dollars

Step 2 ) Multiply both sides by 800 to change 1d into 800d.

\displaystyle\frac{2w}{1d}

\displaystyle\frac{2w}{1d} * \frac{800}{800}

\displaystyle\frac{1,600w}{800d}

This means that the amount of weeks it'll take to reach 800 dollars is...

<u><em>1,600 weeks.</em></u>

Suppose your average, after taking 4 quizzes, is 71 (out of 100). what must your average be on the next 5 quizzes to increase yo
Anton [14]
Short answer: 98
Remark

when you have an average of 71, it's like saying that you took 4 quizzes and got 71 on all of them. 
Step One
Find the total point count for the 4 quizzes.
T_4 = 71 * 4 = 284

Step Two
Create an equation that will give you the necessary point count to average 86.

284 + 5*x = 86 * 9
Why did we do this? It is because you have 9 quizzes altogether. All nine must be something that gives a point count of 86 on each quiz.  You have to put together 9 such quizzes with a total count of 774.

Step three 
Solve the equation.
284 + 5x = 774  Subtract 284 from both sides.
5x = 774 - 284
5x = 490   Divide by 5
x = 490/5
x = 98

You must get an average of 98 on the next 5 quizzes
