Answer:
Length is 24 feet and width is 9 feet.
Step-by-step explanation:
It is given that length of a rectangular wall is 6 feet longer than twice its width.
Let x feet be the width of wall.
Length = 2x+6 feet
Area of rectangle is
It is given that area of a rectangular wall of a barn is 216 square feet.
Splitting the middle term, we get
Width can not be negative. So width is 9 feet.
Length
Therefore, length is 24 feet and width is 9 feet.
Answer:
it is proportional
i can't make the graph, but the table would go
x 0 1 2 3 4 5 6
y 3 4 5 6 7 8 9
and then plot those points on the graph
if you need to label, then x would be labeled weeks and y would be total money saved
Answer:
Step-by-step explanation:
The constant of proportionality is usually presented as the variable k. It is usually written as:
f(x) = kx
where f(x) means a function of x. It can also be another variable, for example, y,
We test each pair to find k,
24 = 6k
k = 24/6 = 4
72 = 18k
k = 72/18 = 4
216 = 54k
k = 4
648 = 162k
k = 4
Thus, the answer is A. yes and k=4.
Answer:
<h3>she should mix 1.2 quarts of sauce with 17% sugar with 1.4 quarts of sauce with 30% sugar</h3>
Step-by-step explanation:
X= quarts of sauce # 1 ( 17% of sugar)
Y= quarts of sauce # 2( 30 % of sugar )
General Balance
EQ (1)
SUGAR BALANCE
EQ (2)
replace Y from eq(1) into eq(2)
