Hey there!
The main concept of pre-algebra is solving equations for variables in them.
For example, let's say you have the algebraic equation below.
x+1=3
With algebra, you need to figure what x is equal to. To do so, you will use inverse operations on both sides of the equation to isolate x one side, showing what it is equal to.
We would subtract 1 to both sides to isolate x on one side.
x+1-1=3-1
As you can see, +1-1=0, therefore, this would give us x+0, or just x. Now it is isolated and will show us what it is equal to.
x=3-1
x=2
Therefore, in our equation x+1=3, x would be equal to 2.
I hope this explanation helps! Have a great time here at Brainly!
3) you’re subtracting 9 each time.. the 3 missing numbers are -39,-48,-57
Answer:
26cm
Step-by-step explanation:
Radius is half of diameter
In order to get the diameter of the circle with a radius of 1e cm you multiply it by 2
13*2=26cm
So, with that being said, your diameter is 26cm
Answer:
Step-by-step explanation:
Given
Find the length of HG
First, it should be noted that the displayed figure is a trapezium
<em>The area of a trapezium is calculated by multiplying the sum of parallel sides by half its height;</em>
In this case;
Substitute the values of Area, HE and EF
Divide both sides by 4
Subtract 12 from both sides
<em>Hence, the length of HG is 5mm</em>
For this case we have the following functions:
m (x)
p (x)
Where,
x: independent variable
m, p: dependent variables
For the value of x = 7 we have:
m (7)
p (7)
For this case it is true that:
m (7) = p (7)
Therefore, both functions have the same output argument for the same input value.
Answer:
C) Both m (x) and p (x) have the same output value at x = 7.
