2x + 3y/4 = 5....multiply everything by 4
8x + 3y = 20
3y = -8x + 20
y = -8/3x + 20/3 or y = (-8x + 20) / 3
1 pound = 16 ounces
8 * 16 = 128 ounces
Answer:
The length of the rectangular field is 12 ft and the width is 5 ft.
Step-by-step explanation:
The area of a rectangle is:

The area of a rectangular field is, <em>A</em> = 60 ft.
The length of the field is:
l = w + 7
Compute the width of the field as follows:


Factorize the last equation by splitting the middle term as follows:

Now, since the width of rectangular field cannot be negative, the width is 5 ft.
Compute the length as follows:
l = w + 7
= 5 + 7
= 12
The length of the rectangular field is 12 ft.
Answer:
A, C and E
Step-by-step explanation:
Simplify each expression to lowest terms. Equivalent expressions will be any expressions which are equal after simplifying to lowest terms.
A. -1/9 * 6 = -6/9 = -2/3
B. -15/10 = -3/2
C. 12/-18 = -2/3
D. -3/4 * 2/1 = -6/4 = -3/2
E. -8/9 * 3/4 = -24/36 = -2/3
The answer to 10 is A......the answer to 11 is D...the answer to 12 is
