Answer:
55 decrease by 5 is 50, or 55 - 5 = 50.
Step-by-step explanation:
Let x represent the missing number.
When you hear the words decrease, minus, that tells you to subtract.
Before we subtract, if there is a variable, we must do the opposite of subtraction, we need to add.
50 + 5 = x
Which means x = 50 + 5.
50 + 5 = 55.
Therefore, x = 55.
Answer:
<h3>d. The roots are real, rational and equal.</h3>
Step-by-step explanation:
The discriminant of a quadratic equation is expressed using the equation:
D = b²-4ac. It talks about the nature of the roots of a quadratic equation.
If D>0, then the roots is real and unequal/distinct
If D<0 the roots are unreal and imaginary
If D = 0, the roots are real and equal (one real root)
According to this question, since the root given is a real value and also one value, then the the roots are real, rational and equal. Note that the root is rational since we can write it as a ratio of two integers e.g 34 = 34/1. 34 and 1 are integers
The value of V illustrated in the ratio V : 33= 7 : 11 is 21.
<h3>What is a ratio?</h3>
It should be noted that a ratio is simply used to show the relationship between the variables and illustrate the comparison.
In this case, the value of V can be illustrated as:.
V/33 = 7/11
Cross multiply
11V = 33 × 7
V = (33 × 7) / 11
V = 21
Therefore, V is 21.
