loris book has 6 times more pages than sals book. the combined number of pages for the two books is 532. how many pages loris bo

julia-pushkina [17]

Your equation would be x+6x=532. You would add the "x's" together to get 7x=532. You would then divide each side by 7 resulting in x=76. This means Sal's book has 76 pages. To get Lori's book, you just times Sam's by 6 (76×6) which is 456. Lori's book has 456 pages.

Write an equation of a line that passes through the point (1. -4) and has a slope of -3

Anna71 [15]

To answer this, you need to know the slope point formula:
y - y1 = m (x - x1)

In this case, (1, -4) represent y1 and x1. m is equal to the slope, which is -3.

y - (-4) = -3 (x - 1)
y + 4 = -3x + 3
y = -3x + 3
-4
y = -3x - 1

Answer: y = -3x -1

The Martinez family walked three over five of a mile in three over eight of an hour. What is their unit rate in miles per hour?

Vikki [24]

Answer:

three-fifths over three-eights equals one and three-fifths miles per hour

Step-by-step explanation:

The martinez family walked three over five of a mile; this means they walked 3/5 of a mile.
They walked such distance in in three over eight of an hour, this means 3/8 of an hour.

To find the rate in miles per hour, we have to divide 3/5 divided 3/8.

$\frac{3}{5} /\frac{3}{8}$

TO make division of fraction, we must invert the second fraction and multiply them:

$\frac{3}{5} *\frac{8}{3} =\frac{8}{5}$

The ratio is 8/5 miles per hour. In the answer given it is expressed as a mixed numer 1 3/5 that is equal to 8/5.

To transform a fraction to a mixed number, you have to divide numerator by denominator. Explanation is in figure attached.
