Answer:
x + y =5 .......eqn (1)
x - y =3 .......eqn(2)
using substitution method
x + y = 5
-
x - y = 3
0 + 2y=2
y = 2/2
y = 1
substitute y in egn(1)
x + 1 = 5
x = 5-1
x = 4
then (x, y) = (4,1)
Does x=5 satisfy the equation 3x + 2 +5x= 95 explain
Answer:
No
Step-by-step explanation:
3x + 2 +5x
if x=5
3(5)+2+5(5)
=15+2+25
=42 which is not equal to 95
No, it doesn't satisfy the equation
Step-by-step explanation:
3x + 2 +5x = 95
Now putting the value of x
3×5 + 2 + 5×5 = 95
15 + 2 + 25 = 95
42 ≠ 95
Hence, x = 5 doesn't satisfy the equation 3x + 2 +5x= 95

The area of each small square is 16 square centimeters. What is the side length of the window? Explain
Answer:
Length=4 cm
Step-by-step explanation:
Solve for L
L*W=A
16 cm^2=L*W
Since this a square. W will equal L.
So [tex]\sqrt{16} =4[/tex]
Meaning that the length is 4
The area of a square is given by:
Area = Side²
If the area of a square is 16 square centimeters, the side length of the window is 4 cm.
What is a square?A square is a four-sided polygon, whose all sides are equal in length and whose opposite sides are parallel to each other.
We have,
Area of the square = 16 square centimeters
The area of a square is given as:
Area = side²
Area = 16 cm²
16 cm² = side²
Square root on both sides
[ 4² = 16 ]
√16 cm² = √side²
Side = 4 cm
Thus if the area of the square is 16 square centimeters, the side length of the window is 4 cm.

Answer:
If you rotate the triangles so that they look the same, one side of both of them are labeled. This gives you the fraction 9/12, or 3/4. The smaller triangle is 3/4th of the larger one. If the larger triangle has 4 on one side, then let's make the equation 3/4 = y/4. The length of y is 3. :)

Graph the linear equation 5x-4y < 20
Answer: (See attached image file)
Step-by-step explanation:
Start by plotting given key featuresBased on the problem, we know that the x-intercept is (0,4) We find this by plugging in 0 for y, and solving for x (5x = 20)(x = 20/5 = 4) (4, 0) We can also easily solve for the y-intercept, which is (0,-5)We find this by plugging in 0 for x, and solving for y(-4y = 20)(y = -5) (0, -5) Since we know that the equation is linear, seeing as the highest exponent is 1, we know that these two points have to be connected by a single, straight line.Finally, we shade in the side to the LEFT of the line. This is because the equation asks for LESS THAN. If however the question had been 5x-4y>20, we would shade in the region to the right.

You are a graphic artist. You are given an image that is 1.2 inches tall and 2.1 inches wide. Your customer wants the image enlarged to create a banner 7 feet wide. Calculate how tall your banner should be to create a proportional image. Remember to include correct units in your answer!
Height / Width = 1.2in / 2.1in
Height / Width x / 84in (7feet)
Solve for X using cross multiplation
2.1x = 1.2 * 84
2.1x = 100.8
x (height) = 48 inches or 4 feet.
