Answer:
x=9
Step-by-step explanation:
y=3x+18=5x
thus 3x+18=5x
subtract 3x from both sides 18=2x
simplify for x x=9
The required solution to the given system of equations is (x, y) = (9, 45).
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The system of equations is given the question as:
y = 3x + 18
y = 5x
To solve this system of equations by substitution, we can start by substituting the equation y = 3x + 18 into the second equation, which gives us:
5x = 3x + 18
Then we can solve this equation for x:
2x = 18
x = 9
Now that we have found the value of x, we can substitute it back into either of the original equations to find the value of y:
y = 3x + 18 = 3(9) + 18 = 27 + 18 = 45
Therefore, the solution to the system of equations is (x, y) = (9, 45).

A cylinder has a total surface of 3,41946cm2 and a diametre of 0,66cm. What is its height? Step by step
Answer:
Total surface Area(A) = 2pi*r(r+h)
Diameter D= 2r
r=0.66/2=0.33cm
A=3.41946
3.41946=2*3.143*0.33(0.33+h)
3.41946=2.0744(0.33+h)
3.41946/2.0744=(0.33+h)
1.6484=0.33+h
1.6484-0.33=h
h=1.3184cm
Step-by-step explanation: Total surface area is different from area around the cylinder.

Sammy earns money for college by walking dogs and mowing lawns. She earns $3 for each dog she walks and $25 for each lawn she mows. Which expression can be used to determine the amount of money she earns from walking w dogs and mowing m lawns
Answer:
x = 3w + 25m
Step-by-step explanation:
The number of dogs she walks (w) and the number of lawns that Sammy mows (m) need to be multiplied by the amount of money that Sammy makes from each individual action. Both of these products are then added together to equal the total amount of money that Sammy has earned. All of this can be represented with the following expression where x is the total amount of money earned...
x = 3w + 25m

Help plssss
Answer:
-5
Step-by-step explanation:
we distribute the 3 and 2 on both sides to get:
3x+3=2x-2
we can subtract 3 on both sides to get
3x=2x-5
Now we subtract 2x on both sides to get
x=-5

Leah is training for a bike race she start by biking 8 miles during every training session each week she plans to increase the distance of her training session by 3/4 mile W the number of weeks write an expression to show the distance Leah bikes in a training session after W weeks
Answer: 8 + 3/4W
Step-by-step explanation:
From the question, we are informed that Leah is training for a bike race she start by biking 8 miles during every training session and that each week she plans to increase the distance of her training session by 3/4 mile W the number of weeks.
The expression to show the distance Leah bikes in a training session after W weeks will be:
= 8 + 3/4W
For example, after 4 weeks, the distance biked will be:
= 8 + 3/4W
= 8 + (3/4 × 4)
= 8 + 3
= 11 miles

Help, please! In the diagram, FH = 1/3AC and 3FG = AB. What additional information is necessary to prove that ΔABC is similar to ΔFGH, using the SSS similarity theorem?
1.
2.
3. BC/GH = 3
4. BC/GH = 1/3
=======================================================
Explanation:
The order of the letters is very important. This is because the order tells us how the angles pair up and that leads to telling us how the sides correspond to one another.
Note with ABC and FGH, the first and last letters are AC and FH respectively. These sides correspond. We're told that FH is 1/3 as long as AC when your teacher wrote FH = (1/3)*AC; we can solve for AC to get AC = 3*FH.
Going back to ABC and FGH, we see that the first two letters of each are AB and FG. This is another pair of corresponding sides. We're told that 3*FG = AB. So AB is three times longer than FG.
So far we can see that
AC = 3*FHAB = 3*FGThe missing information we need is that BC = 3*GH. If we know this, then we can use the SSS similarity theorem to prove the triangles are similar. Note how BC are the two last letters of ABC while GH are the last two letters of FGH.
Starting with BC = 3*GH, we can divide both sides by GH and we get BC/GH = 3.

Carmen enters a painting in an art contest. The contest rules say that all paintings must be rectangular with an area no greater than 3,003.84 cm2 . Carmen's painting is 16 cm wide.
What is the greatest length the painting can have and still have an area within the contest rules?
Answer:
[tex]187.74\:\mathrm{cm}[/tex]
Step-by-step explanation:
The area of a rectangle is given by [tex]l\cdot w[/tex]. Therefore, we can set up the following inequality:
[tex]l\cdot 16 \leq 3,003.84[/tex].
Solving this inequality, we have:
[tex]l \leq 187.74[/tex].
Therefore, the largest length Carmen's painting can be is [tex]\fbox{$187.74\:\mathrm{cm}$}[/tex].

can someone pls help me i need to know what is 2x - 1 = 7
Answer:
The solution for x would be 4.
Step-by-step explanation:
2x - 1 = 7
The value of x is unknown, but you do know that you are multiplying 2 by x. So, if you rewrite the equation as 7+1=2x, you know that 8=2x. If you then divide both sides by 2, you're left with 4=x which would mean that the variable x has a solution of 4
