Answer:
Step-by-step explanation:
first look at all the equation and solve them. When you get the all of there answer then divide the answers by the sides. And then you will find your answer!
Answer:
The screenshot shows the correct answers; 5x + 5y = 25 is linear.
For a equation to be linear:
- The equation should not have square root, cube root, etc.
- The value of x is not greater than one. X should not have an exponent.
- X is not in a denominator of a fraction.
- "xy" should not be in the equation.

The number is -10.4
<u><em>Explanation:</em></u>
Assume that the number we are looking for is x.
Now, we want to get 10 times te sum of half the number and 6 and equate this expression to 8. Then we can solve for x
<u>Let's take this step by step:</u>
half the number is 0.5x
the sum of half the number and 6 is 0.5x + 6
10 times the sum of half the number and 6 is 10(0.5x +6)
10 times the sum of half the number and 6 equals 8 is 10(0.5x+6) = 8
<u>Now we can solve for x as follows:</u>
10(0.5x + 6) = 8
5x + 60 = 8
5x = 8 - 60
5x = -52
x = -52/5
x = -10.4

cut the shape into a square and triangle.
square: 9 x 11= 99
triangle: (6x11)/4 =16.5
99+16.5=115.5
