Answers
Answer:
240; 24
Step-by-step explanation:
Given that:
Sum of two numbers = 264
One number ends with '0'
Second number = first number without '0'
Let the first number be 'a'
Since the second number is the first number with '0' erased, then,
Second number = (a ÷ 10)
Therefore, the expression becomes :
a + a/10 = 264
Multiply the equation by 10
10a + a = 2640
11a = 2640
a = 2640/11
a = 240
Therefore ;
a = 240 ;
a/10 = 240/10 = 24
The numbers are 240 and 24

Subtract 2 from the both sides,
x - 2 = 3g + 2 - 2
x - 2 = 3g
Now, Divide 3 from both sides,
(x-2)/3 = 3g/3
g = x-2 / 3
In short, Your Answer would be x-2 /3
Hope this helps!
The concept of the linear system, subtraction, and division is applied.
g is taken as a subject then the equation is .
What is the linear system?
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
x = 3g + 2 is a single linear variable equation.
Rearrange x = 3g + 2 to make g the subject.
Subtract 2 from the equation.Then
x - 2 = 3g
Divide the equation by 3. Then
Thus, g is taken as a subject then the equation is .

Answer:
Draw a graph that joins the points (100, 155) and (200, 245) and has a slope = 0.9
Step-by-step explanation:
x variable represents total megabytes of data used
y variable represents total monthly charges
The company charges $155 (y) for 100 megabytes (x) means that the point (100, 155) belongs to the equation.
The company charges $245 (y) for 200 megabytes (x) means that the point (200, 245) belongs to the equation.
With these two points, the slope is computed as follows:
(245 - 155)/(200 - 100) = 0.9

Step-by-step explanation:
if ax^2 +bx + c ====>discriminant formula is b^2 - 4ac from the quadratic formula
x2 + 3x + 1 = 0
Then;
a=1
b=3
c=1
b^2 - 4ac = 3^2 -4*1*1
= 9-4
= 5
