Answer:
We are given that:
variables x and y vary directly, this means that:
y = kx where k is the constant of proportionality
Now, we are also given that:
y = 45 at x = 40.
We will use these values and substitute in the above relation to get k as follows:
y = kx
45 = 40k
k = 45/40 = 9/8 = 1.125
Based on the above calculations, the equation that relates x and y is:
y = 1.125x

Answers
Answer:
2. yes; the equation can be written as y = kx; k = 1
Step-by-step explanation:
x-y = 0
That means x and y have to be the same value.
If you multiply a number by 1, you get the same thing.
If you multiply x by one, you get y (the same value).

x−8.2=−9.09
What is the solution to the equation?
Enter your answer in the box.
Answers
Explanation: In order to solve for X we will need to do inverse operation and add 8.2 to -9.02 which would give us -0.89. You can always check if your answers correct by plugging your final answer in for X
The value of x in x−8.2=−9.09 is 0.89.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
x−8.2=−9.09
Now, we have to solve for x
Add 8.2 on both side
x-8.2 + 8.2 = -9.09 + 8.2
x= 0.89
hence. the value of x is 0.89.

Answers
Answer: 29.5 inches tall.
Step-by-step explanation:
If Eva was 1.5 inches taller than her original height, she would be half of Maria’s height. So, we divide Maria’s height by two to find the height Eva would be if she was 1.5 inches taller.
62 / 2 = 31 inches
Next, to find Eva’s real height, we subtract 1.5 inches from the 31 inches. This is because Eva would only be half Maria’s height IF she was 1.5 inches taller, but she is not, so therefore we can deduct it.
31 - 1.5 = 29.5 inches
Therefore, Eva’s height is 29.5 inches tall. We can prove this, as well.
29.5 + 1.5 = 31 inches
31 * 2 = 62 inches
Therefore, Eva is 29.5 inches tall.

Concept used:
- The sum of the internal angles of a triangle is 180
- With two parallel line and one oblique, the angles internal and opposite are congruent (ex: m3 and m4)
- An isosceles triangle has the base angles congruent
Step-by-step explanation:
m1 is a rectangle angle
m2 is 180-m1-22
m3 is 180-m2
m5 is 180-m4
m6 is 180-m5-m5
m3 = m4 = m7 = m8

Could somebody please help me find the answers for 'x' for these pictures?
**Please let me know which one you solved along with the answer**
Answers
Answer:
(in order) #1
for the first one you have a vertical angle. Vertical angle is basically any 2 lines who intersect each other. The opposite sides will be congruent.
So in this case
2x+8 and 110 are oppostie sides.
2x+8=110
Which is x= 51
#2
For the second one you have supplementray angles
Now for supplementary angles its basically 2 angles added up that form a straight line And 180 degress is always the measure of a straight line. SO in this case we do
9x+12x+75=180
Which is x=5
#3
This is also a vertical angle pair and their congruent just like #1
So 5x+5=65
x=12
1. x=51
2. x=5
3. x=12
