Answer:
C ; 7 and 8
Step-by-step explanation:
The correct question is as follows;
On a number line, between which two consecutive whole numbers would 7.8 be located?
Solution
Here, we want to know between which consecutive whole numbers will 7.8 be located .
As we know, 7.8 is a decimal, it is same as 7 + 0.8
It is greater than 7 but less than 8;
Thus it is between 7 and 8

Let's find the discriminant of <span>x^2+9x+14=0. Here, a=1, b=9 and c=14.
The discriminant is b^2-4ac. Substituting the above numeric values,
9^2-4(1)(14) = 81-56 = 25
The sqrt of 25 is 5. Thus, your polynomial has two unequal, real roots.
Off the point example: If the discriminant were zero, your poly would have two real, equal roots.</span>
Answer:
The answer is X = 18
Step-by-step explanation:
2x/3 - 7 = 5
Multiply both sides if the equation by 3 : 2x - 21 = 15
Move the constant to the right hand side and change its sign : 2x = 15 + 21
Calculate 2x = 15 + 21
2x = 36
Divide both sides of the eqaution by 2 : 2x = 36
x = 18
Answer X = 18
