Answer:

-7y - 35

Step-by-step explanation:

-3 ( y) = -3y

-3 ( 5) = -15

-4 ( 5) = -20

-3y -4y = -7y

-15 -20 = -35

-7y -35

Find ten rational numbers between -1 by 5 and 1 by 2

uysha [10]

Answer:

Step-by-step explanation:

First both the rational numbers should have same denominators. So, find least common denominator

Least common denominator is 10

$\frac{-1}{5}=\frac{-1*2}{5*2}=\frac{-2}{10}\\\\\\\frac{1}{2}=\frac{1*5}{2*5}=\frac{5}{10}\\\\\\$

Now multiply the numerator and denominators of the both the numbers by 10.

$\frac{-2*10}{10*10}= \frac{-20}{100} \ and \ \frac{5*10}{10*10}=\frac{50}{100}\\\\\\Now\ 10 \ rational \ numbers \ between\frac{-20}{10} \ and \ \frac{50}{100} \ is \\\\\\\frac{-19}{100},\frac{-18}{100},\frac{-17}{100},\frac{-16}{100}.\frac{-15}{100},\frac{-14}{100},\frac{-13}{100},\frac{-12}{100},\frac{-11}{100};\frac{-10}{100}$

: Mark wants to fence 4 rectangular gardens, each with a length of feet 9/1/4 and a width of feet 4/1/2 . What is the total leng

Anastaziya [24]

Answer:

Mark needs 110 ft. fencing to surround all 4 gardens.

Step-by-step explanation:

Mark wants to fence 4 rectangular gardens. So we calculate the perimeter of the each garden by this formula

P = 2(L) + 2(W)

Total Length of the garden = $9\frac{1}{4} + 9\frac{1}{4}$

= $\frac{37}{4}+ \frac{37}{4}$

Length = 18.5 feet

Total width of the garden = $4\frac{1}{2} + 4\frac{1}{2}$

= $\frac{9}{2}+ \frac{9}{2}$

Width = 9.0 feet

Perimeter of the garden = 18.5 + 9 = 27.5 feet

Mark wants to fence 4 garden

Therefore, 27.5 × 4 = 110 feet.

Mark needs 110 ft. fencing to surround all 4 gardens.
