The values of x and y in the following equation system are 20 and 110, respectively.
What are System of equation?simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods to solving systems of equations: graphing, substitution, elimination and matrices.
given a system of equation:
30x + 4y = 1,040.....(1)
12x + 16y = 2,000...…(2)
We will solve it by using substitution method,
Multiply with 2.5 in equation (2) and subtract it from equation (1)
30x + 4y - 30x - 40y = 1040 - 5000
36y = 3960
y = 110
Substitute this value of y in equation (1)
30x + 440 = 1040
30x = 600
x = 20
Therefore, The value of x and y are 20 and 110 respectively for the given system of equation.

A rectangular football field is 6x meters long and 3x meters wide. If its
perimeter is 360 meters, then the value of x is
Answer:dgrgfhtbsdvdsvs
Step-by-step explanation:dssfdfd
Answer:
x = 20
Step-by-step explanation:
perimeter = 2(width) + 2(length)
2(6x) + 2(3x) = 360
12x + 6x = 360
18x = 360
divide both sides by 18
x = 20

Answer:
B 1/3 then reflection across y axis then move figure 2 units to down and 1 right.
Step-by-step explanation:
The figure ABC is bigger than FED so the scale factor is less than one since we are going to ABC to FED. Let look at corresponding sides, AB and FE. AB distance is 3. FE distance is 1 so let divide
[tex] \frac{fe}{ab} [/tex]
[tex] \frac{1}{3} [/tex]
The scale factor is 1/3.
The new points are at A'(-2,0) B'(-2,1) C'(-1,0).
Then we apply reflection.
Since FED is in the 4th quadrant, we are going to reflect across the y axis.
That becomes using formula
(x,y) goes to (-x,y) when reflecting across yaxis.
A''(2,0) B''(2,1) C''(1,0)
Now we will apply the translation. We can simply just move the figure 2 units down and 1 unit to the right.

ΔADE ≈ ΔABC
set up a proportion based on corresponding sides
AD/AE = AB/AC
9/4 = 11/(4 + EC)
9(4 + EC) = 44
36 + 9EC = 44
9EC = 8

Answer:
the pythagoream theorem, a^2+b^2=c^2
1. 13in.
2. 31.6 yd.
3. 16.1 m.
Step-by-step explanation:
c is the hypotonus (the diagonal line on a right triangle)
if you are trying to find c, you square the two sides that are given and then add them up.
For example number 1:
So 5x5=25 and 12x12=144
add those two values together, 25+144=169
the last step is to find the square root of that last sum (169)
√169 = 13.
If we reflect the point (-2,3) over the line y=1, what is the new point?
Answer:
(-2,-1)
Step-by-step explanation:
Since this is a reflection over the y-axis you'll keep the x-coordinate Making it (-2,?) and then since 3 is two away from y=1 on the plane you'd just count downwards two more giving you -1, so the answer is (-2,-1)

Write a simplified equation to solve for X.
Using the equation, solve for x
Answer:
x = 40
Step-by-step explanation:
x + 100 + x = 180 {Straight line angles}
2x + 100 = 180 {subtract 100 from both sides}
2x = 180 - 100
2x = 80 {Divide both sides by 2)
x = 80/2
x = 40
Answer:
x=40
Step-by-step explanation:
2x+100=180
2x=180-100
2x=80
x=40
