3.1 is like a example when it is hiding a zero behind it and you find this when you do a math problem and you don't put zero in front of a number like 100-89 you don't write "011" so that is why it is like that
Answer:
In what?
Step-by-step explanation:
Using the substitution method to solve the linear system the value of x and y is 1 and 2 respectively.
<h3>What is the linear system?</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width.
Given
The equations are shown below.
y = 5 - 3x .....1
5x - 4y = -3 .....2
Substitute equation 1 in equation 2. Then

Then substitute the value of x in equation 1.

Thus, the value of x and y is 1 and 2 respectively.

Answer:
The answer is 6 × 5 × 5 square inches.
Step-by-step explanation:
For each square, the area is 5 x 5 inches and there 6 squares in the picture.
Answer: 8 units^2
Step-by-step explanation:
Since both length and width are cut in half by the overlap the new width and lenghth become 8/2=4 and 4/2=2 so 4 and 2
So find area=lxw so 4*2=8
