Answer:
y is already isolated in the top equation
x = 4
y = 12
(4,12)
Step-by-step explanation:
y is already isolated in the top equation
plug y = 3x into bottom equation
5x + 2y = 44
5x +2(3x) = 44
5x + 6x = 44
11x = 44
x = 4
plug x = 4 into y = 3x
y = 3(4)
y = 12

The value of w varies jointly with x and y, and w = 5 when x = 3/4 and y =2. What is the value of w when x = 4 and y = 3?
Answers
Answer:
A ∝ BCD or A = kBCD (k = constant ), then A varies jointly as B, C and D.
Step-by-step explanation:
The value of 'w' when x = 4 and y = 3 is, 40.
What are ratio and proportion?In its most basic form, a ratio is a comparison between two comparable quantities.
There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.
If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.
Given, The value of w varies jointly with x and y.
Let, w ∝ xy ⇒ w = kxy.
5 = k×(3/4)×2.
5 = (3/2)k.
k = 10/3.
Now, x = 4 and y = 3.
Therefore,
w = (10/3)×4×3.
w = 40.

A countertop is 11 feet long and 4 fee t wide.
What is the area of the countertop in square meters? Use the conversion 1 foot = 0.305 meter. Round your
final answer to 2 decimal place
Answers
Answer:
4.09m^2
Step-by-step explanation:
A countertop is 11 feet long and 4 fee t wide.
Using the conversion
1foot = 0.305 meter
11fet = 11(0.305)
11feet = 3.355 m
4 feet= 4 * 0.305
4feet = 1.22m
Area of the countertop = Length * Width
Area of the countertop = 3.355 * 1.22
Area of the countertop = 4.0931m^2
Hence the required area is 4.09m^2 to 2 decimal places
