a rectangle's length is three more than two times its width if the perimeter of a rectangle is 66 ft what is the measurement of

Lemur [1.5K]

Answer:

The measure of the length is $23\ ft$

Step-by-step explanation:

Let

x-----> the length of rectangle

y-----> the width of rectangle

we know that

The perimeter of rectangle is equal to

$P=2(x+y)$

$P=66\ ft$

$66=2(x+y)$

Simplify

$33=x+y$ -----> equation A

$x=2y+3$ ----> equation B

Substitute equation B in equation A and solve for y

$33=(2y+3)+y$

$2y+y=33-3$

$3y=30$

$y=10\ ft$

Find the value of x

$x=2(10)+3=23\ ft$

Keisha is reading a 350 page book at a rate of 27 pages per day. Use a point-slope equation to determine how many pages she will

Scrat [10]

Answer:

She will still have 80 pages left to read after 10 days.

Step-by-step explanation:

Keisha is reading the book at a rate of 27 pages per day. The book has 350 pages. So , after x days , the no. of pages remaining to read is,

$y = 350 - 27 \times x$ ---------------(1)

Here, the given value of x is 10. So, putting x = 10 in (1) we get,

$y = 350 - 27 \times 10$

= 80

Which table does not represent a proportional relationship? A 2-column table with 3 rows. Column 1 is labeled x with entries 9,

MrMuchimi

Answer:

the one with 12, 18, 22

Step-by-step explanation:

in the first one, 9-3=6 and 6-3=3 so -3 is the constant of the proportionality

in the second one 3-1=2, 2-1=1 so here the constant of proprtionality is -1

in the third one 16+2=18, 18+2=20 so the constant of proportionality is 2

fourth one 4 + 0.5= 4.5 and 4.5+0.5= 5, constant of proportionality is 0.5

fifth one 12+6=18, but 18+6=24

and the rest are all proportional
