Hi there! :)
<u><em>Answer:</em></u>
<u><em>x=23</em></u>
<u><em>*The answer must have a positive sign.*</em></u>
Step-by-step explanation:
This lesson it's about addition property of equality.
First, you add by 8 from both sides of an equation.

And then, you add by the numbers. Simplify and solve.

Final answer: → 
Hope this helps!
Thanks!

Answer:
C
Step-by-step explanation:
change decimetres into metres
length - 7.3m
Width - 4.2m
to find an area, do length times width
7.3 x 4.2 = 30.66 square metres
I hope this helped :)
Answer:
x = 48 and y = 104
Step-by-step explanation:
Given equations are:

From equation 1:

Putting the value of y in equation 2

Now we have to put the value of y in one of the equation to find the value of x
Putting y = 104 in the first equation

Hence,
The solution of the system of equations is x = 48 and y = 104
The value of variable which was assumed for number of hats, is the total number of hats.
Using proportions, the coordinates of the point 3/4 of the way from P to Q are: (0,4).
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
We want to find the coordinates of point M(x,y) 3/4 of the way from P to Q, hence the rule is given by:
M - P = 3/4(Q - P)
For the x-coordinate, we have that:
x + 6 = 3/4(2 + 6)
x + 6 = 6
x = 0.
For the y-coordinate, we have that:
y + 5 = 3/4(7 + 5)
y + 5 = 9.
y = 4.
The coordinates are (0,4).
