you want to make a rectangular dog pen using 20 yards od fencing. The side lengths must be in whole yards. create as many differ

Marina CMI [18]

Rectangular with whole numbers
perimiter=legnth+legnth+width+width=2l+2w
therefor
p=2l+2w=2(l+w)
p/2=l+w

perimiter=20
20=2l+2w
divide by 2 to make simpler
10=l+w
find all combos
l>w so
l=9 and w=1
l=8 and w=2
l=7 and w=3
l=6 and w=4

Does anybody know how to solve for “C”?.

Jobisdone [24]

Answer:

c = (b+3a)/2

Step-by-step explanation:

Solve for c:

1/ac = 2/ab - 3/bc

Multiply both sides by abc:

abc/ac = 2abc/ab - 3abc/bc
b = 2c - 3a
b + 3a = 2c
2c = b + 3a
c = (b + 3a)/2

1/7 x X =1 X x 1/11=1 1 divided by 1/5=

guajiro [1.7K]

Answer:

x = 7
x = 11
5

Step-by-step explanation:

$\frac{1}{7} \times x = 1$

$7 \times \frac{1}{7} x = 7 \times 1$

$7 \times \frac{1}{7} x = 7$

$\boxed{\green{x = 7}}$

◇◇•◇◇

$x \times \frac{1}{11} = 1$

$\frac{1}{11} x = 1$

$11 \times \frac{1}{11} x = 11 \times 1$

$11 \times \frac{1}{11} x = 11$

$\boxed{\green{x = 11}}$

♤♤•♤♤

$1 \div \frac{1}{5} = 1 \times \frac{5}{1}$

$1 \times 5$

$\boxed{\green{= 5}}$
