5/6 divided by 7/8. please show work

Elis [28]

When you are dividing fractions you need to flip the second fraction and change the sign to multiply. So for this question you'd get:
5/6 x 8/7
then you multiply as normal.
getting you the answer of 40/48
this is equivalent to 5/6

Write an equation of the line in slop intercept form

Marat540 [252]

Answer:

$m=-\frac{4}{3}$

Step-by-step explanation:

to find the slope use the formula $m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{0-4}{0-(-3)}$

simplify

$m=\frac{0-4}{0+3}$

$m=\frac{-4}{3}$

move the negative in front of the fraction

$m=-\frac{4}{3}$

Are 2(6.1x+25.3y+2.1x-3.9y) and 4(4.1x+ 10.7) equivalent

Vlada [557]

Answer:

Multiply the number outside the parentheses by each term inside the parentheses

=2(6.1x+25.3y+2.1x-3.9y)

=(2*6.1x)+(2*25.3y)+(2*2.1x)+(2*-3.9y)

=12.2x + 50.6y + 4.2x - 7.8y

combine like terms

= 16.4x + 42.8y

=4(4.1x+ 10.7)

=(4*4.1x) + (4*10.7y)

=16.4x + 42.8y

Yes, the two expressions are equivalent.

A phone company offers two monthly plans. Plan A costs $25 plus an additional $0.07 for each minute of calls. Plan B costs $16 p

Blizzard [7]

Answer:

1) For 450 minutes of calling the two plans cost the same.

2) The cost when the two plans cost the same is $56.5.

Step-by-step explanation:

The cost of both plans can be modeled by linear functions.

Plan A:

$25 plus an additional $0.07 for each minute of calls.

So, for t minutes of calls, the cost is:

$A(t) = 25 + 0.07t$

Plan B:

$16 plus an additional $0.09 for each minute of calls.

So, for t minutes of calls, the cost is:

$B(t) = 16 + 0.09t$

Q1: For what amount of calling do the two plans cost the same?

This is t for which:

$A(t) = B(t)$

$25 + 0.07t = 16 + 0.09t$

$0.02t = 9$

$t = \frac{9}{0.02}$

$t = 450$

For 450 minutes of calling the two plans cost the same.

Q2: What is the cost when the two plans cost the same?

This is A(450) or B(450), since they are the same.

$B(450) = 16 + 0.09*450 = 56.5$

The cost when the two plans cost the same is $56.5.
