A local concert promoter purchases 2 3/4 pages of ads. When one of the concerts is cancelled, the promoter cancels 1 5/8 pages o

Lynna [10]

Answer:

1 $\frac{1}{8}$ pages

Step-by-step explanation:

Since the concert promoter started with 2 $\frac{3}{4}$ pages of ads but had to cancel 1 $\frac{5}{8}$ , subtracting the cancelled amount from the original amount will give the amount of advertising space the promoter is now actually using:

2 $\frac{3}{4}$ = 2 $\frac{6}{8}$

- <u>1 $\frac{5}{8}$ </u> - <u>1 $\frac{5}{8}$ </u>

1 $\frac{1}{8}$ pages

In order to subtract fractions, you need to have like denominators, so you need to convert $\frac{3}{4}$ into an equivalent fraction with a denominator of '8'. Since 4 x 2 = 8, then you also need to multiply the numerator by the same factor: 3 x 2 = 6.

Alonzo wrote the equation x = 2+4y-5. Which equation is equivalent?

Rainbow [258]

Consider the equation $x = 2+4y-5$ , it can be expressed as $x = 4y-3$ .

Now, we have to write the equivalent equation.

Since, Equivalent equations are those equations which have exactly same solution. We can say that the two equations are equivalent if solution of one equation is the solution of other equation.

So, consider the equation $x = 4y -3$
