Answer:
Maybe 60
Step-by-step explanation:
I don't know just please guess sorry but can you mark as brainiest.
To solve for the solution of this system of linear equation, it is best to use substitution. From the first equation, x = 3y
Substituting the expression on the right for the value of x on the second equation,
-2(3y) + 3y = 16
Solving for the value of y gives y = -5 1/3
With this value of y, solving for x gives x = -16
Thus, the solution for this system of linear equation is (-16, -5 1/3)
First let’s reword this to, 40% of what number is 8.8.
When we say this, it means that 2/5x=8.8.
Once we solve we get x=22
Given expressions:
Area of a rectangle = L W
Area of a triangle = 
Problem;
Create problems using the formula;
Solution:
Problem 1; Find the area of a rectangle whose length is 10cm and the width is half the size of the length?
Given parameters:
Length of rectangle = 10cm
Width of rectangle =
x length =
x 10 = 5cm
So, the area of the rectangle = 10cm x 5cm = 50cm²
2. A triangle with a base length of 30cm and a height of 2cm will have an area of what?
Given parameters:
base length = 30cm
height = 2cm
Solution:
Area of a triangle =
x b x h
Area of a triangle =
x 30 x 2 = 30cm²
The area of the triangle will be 30cm²
