we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=Kx
where
K is the constant of proportionality or slope of the linear equation
In this problem
x ----> is the number of months
y -----> is the total amount savings
we have the ordered pairs
(4,80) and (7,140)
so
Find the value of K
K=y/x
For (4,80)
K=80/4=20
For (7,140)
K=140/7=20
The value of K is the same for both ordered paits
that means------> is a proportional relationship
therefore
the linear equation is
y=20x
the answer is the option A, C and D

Step-by-step explanation:
0.3:0.1
Step-by-step explanation:
first convert the % to decimals.
75%=0.75
25%=0.25
then look for a common factor and divide be that, in this case its 5.
0.75/5=0.15
0.25/5=0.5
now since these arent in the simplified form, you gotta divide again by 5.
0.15/5=0.3
0.5/5=0.1
Explanation:
Remember the following properties of real numbers:
Reflexive property:
This property states that a number is always equal to itself.
This property is different from the equivalent equations property. In fact, two equations that have the same solution are called equivalent equations,
Division property of equality:
This property states that when we divide both sides of an equation by the same non-zero number, the two sides remain equal.
Substitution property of equality:
This property states that if x = y, then x can be substituted in for y in any equation.
We can conclude that the correct answer is:
Answer:Drop Down 1: reflexive property
Drop Down 2: division property of equality.
Drop Down 3: substitution
Answer:
<u>The correct answer is x = 3/2</u>
Step-by-step explanation:
2 √2x = 2√3, what is the value of x?
Let's solve for x, this way:
2 √2x = 2√3
√2x = √3 (Dividing by 2 at both sides)
(√2x) ² = (√3) ² (Raising both sides at the 2nd power)
2x = 3
x = 3/2 (Dividing by 2 at both sides)
<u>The correct answer is x = 3/2</u>
