Answer:

n = 1

Step-by-step explanation:

Represent the number by n. Then "seven less than twice a number is -5 becomes 2n - 7 = -5

Next we must solve for n. Adding 7 to both sides yields 2n = 2, so that

n = 1

Yara has 2 rectangular gardens in her backyard. The smaller garden is 1/2 foot long and 2/3

dimulka [17.4K]

Dimension of smaller garden :

l = 1/2 ft.

b = 2/3 ft.

Dimension of bigger garden :

L = 4 ft.

Let , breadth be x ft.

We know , area is given by :

Area = L×B.

Area of small garden = $\dfrac{1}{2}\times\dfrac{2}{3}=\dfrac{1}{3}\ ft^2$

Area of big garden $=4\times x=4x\ ft^2$

Hence, this is the required solution.
