Answer:
Step-by-step explanation:
4x -39 > -43 8x + 31 < 23
Add 39 to both sides Subtract 31 from both sides
4x -39 + 39 > -43 + 39 8x + 31 - 31 < 23 - 31
Simplify Simplify
4x > -4 8x < -8
Divide both sides by 4 Divide both sides by 8
4x / 4 > -4 / 4 8x / 8 < -8 / 8
Simplify Simplify
x > -1 x < -1
Answer: A
An equation is formed of two equal expressions. The quadratic equation that can be used to find x, the smaller number is x²+x-272.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the first number be x.
Now since the two numbers are consecutive numbers the other number will be (x+1). Also, it is mentioned in the problem that the product of the two numbers is 272. Therefore, the equation that can represent the product will be,
Thus, the quadratic equation that can be used to find x, the smaller number is x²+x-272.

Answer:
28 bikes are blue
Step-by-step explanation:
Set up the ratio:
Blue : Black
4 : 5
Find the total # of bikes in the ratio:
4 + 5 = 9
Find the relationship between 63 and 9:
63/9 = 7
Multiply both sides of the ratio by 7:
4(7) = 28
5(7) = 35
28 : 35
Therefore, the number of blue bikes is 28.
When dealing with negatives, the higher the number is, the lower the value is. therefore, -34 is less that -9.
