Is it possible to solve the following system by using substitution? Which method, substitution or elimination is more efficient? Complete the explanation.
braceleftze 3x − 2y = 11
x + 2y = 25
possible to use substitution. Solve the second equation for x to get x =
y + 25. Substitute x in the first equation and solve for y. Then substitute this value for y in either original equation to get a solution of (
). The elimination method is
efficient because there are
calculations and they are
to do.
Answer: x = 5.5 and y = 2.75
Adele also must choose between leather or cloth seats for her vehicle. Leather seats come in three color choices; brown, black, and blue. Cloth seats come in two color choices; tan and gray. Using multiplication, Adele says she has (2)(3)(2), or a total of 12, choices for seat covers. Is she correct? Explain why or why not.
Answer:
6 choices
Step-by-step explanation:
Adele has to choose between leather or cloth seats for her car.
Leather has three colors, those being brown, black, and blue.
Cloth has two color choices, tan and gray.
You multiply the amount of choices for leather and cloth:
2 x 3 = 6
Adele is not correct.

Land developers are dividing a property into several sections to develop a new neighborhood, as shown below.
• Find the area, in square blocks, of the mall section of the property. Show all your work.
• Find the area, in square blocks, of the park section of the property. Show all your work.
• Find the total area, in square blocks, of the sections with homes. Show all your work.
• If the developers paid $500.00 per square block, how much did they pay for all the property being developed? Explain your answer.
Answer:
$97500.00
Step-by-step explanation:
the homes of the homes facing south is 10 times (7 plus 3) = 100 blocks
the area of the east facing homes is 8 times 10= 80 blocks
and the area of the trapezoid is 5 plus 3 times 3 = 15 blocks
so 100+80+15= 195 square blocks
195 times 500 = $97500.00

Jayden bought a playstation 4 for $396.62, including sale tax. He made a down payment of $35.00 and paid the balance in 12 equal monthly payments. What was Jayden's monthly payment for the playstation 4?
Answer:
$30.135 or if rounded up $30.14
Step-by-step explanation:
subtract 35 from 396.62
396.62 - 35 = 361.62
divide 361.62 by 12
361.62/12 = 30.135
Answer:
e
Step-by-step explanation:
Jayden bought an item for $396.62 with sale tax.
He already payed $35 as a down payment.
396.62 - 35 = 361.62
He pays the item in 12 equal monthly payments.
361.62 / 12 ≈ 30.14
(really equal to 30.135)
he pays abt $30.14 each month

Hey there!
Let's solve this equation for N.
First, let's work out 36+9:
45
45-N=1
subtract 45 from both sides:
-N=1-45
-N=-44
Divide both sides by -1:
N=44 (Option B)

Write an equation that you can use to solve for x.
Enter your answer in the box.
Answer:
40 degrees
100-60=40
Step-by-step explanation:
The angle x is in another angle that looks like 100 and 100 minus 60 is 40.
Hope this helps and if it is correct.
Answer:
Step-by-step explanation:
Remark
x + 60 together make up an angle that is vertically opposite the 100 degree angle.
Vertically opposite angles are equal.
Equation
x + 60 = 100
Solution and Answer
x + 60 = 100 Subtract 60 from both sides.
x + 60-60 = 100 - 60 Combine
Answer: x = 40

(20 POINTS) One side of a trapezoid is extended and the dotted line forms a right angle with the extended line.
Answer: p = 115* (degrees)
Explanation:What we know:
The trapezoid forms a right triangleThe right triangle has the angles 25*, 90*, and an unknownThe internal angles of a triangle add up to 180*The unknown value p is a supplementary angle to the right triangle's unknown angleHow to solve:
By finding the degree of the 3rd angle in the right triangle, we can use the rules of supplementary angles to find the value of p.
We will use D to represent the total amount of degrees, which will equal 180*. X will represent an unknown angle. An asterisk represents the degree symbol.
Process:Missing right triangle angle
Set up equation D = 25 + 90 + x
Substitute 180 = 25 + 90 + x
Simplify 180 = 115 + x
Isolate variable -115 -115
Solution 65* = x
Value of p using supplementary angles
Set up equation D = x + p
Substitute 180 = 65 + p
Isolate variable -65 -65
Solution 115* = p
Answer: p = 115*Check:
We can do a check based on estimation. Assuming that the trapezoid and triangle form a box with all 90* corners and that p = 115*, then adding p and all of the other trapezoid angles should result in 360*
Firstly, we need the values of these 4 angles.
The first angle, labeled p, should be 115*. If our equation is untrue, then this value will fail the check.
The second angle will be the one at the bottom-left, which is 90* according to our box statement.
The third angle is the one located at the bottom-right, which is also 90* from the box statement.
The fourth angle is not 90* or 115*, but we can solve its value.
Because we have stated that the right triangle and trapezoid form a box with 4 90* corners, the sum of the fourth angle and the 25* from the right triangle must form a right angle. Let's find the value:
D = 25 + x
90 = 25 + x
(90 = 25 + x) - 25
65* = x
Therefore, the fourth angle has 65*
Now, adding the degrees from all 4 angles should result in a total of 360*. If it does, then our value of p = 115* will pass the check.
D = 90 + 90 + p + x
360 = 90 +90 + 115 + 65
360 = 180 + 180
360 = 360
Therefore, p = 115*
Answer:
C
Step-by-step explanation:
A and B are out because we can already tell that 65 and 75 are smaller than the 90 degrees whichs this angle is even higher than.If you see or use a protrater you can see it seems more likely to 115 because 155 would be much more open.

Answer: ∠DOB: 48°
Step-by-step explanation:
1. we need an equation first. the sum of all angles (108°, n°, 2n°) is equal to 180°. we can depict this with the equation: 108°+2n°+n°=180°
2. now we can solve for the missing variable, n.
108°+3n°=180° → subtract both sides by → 3n°=72° → divide both sides by 3 → n=24°
3. now that we know that n=24°, we can solve the value of ∠DOB. we can see that ∠DOB is 2n° which we just plug the number we got for n into the equation. 2*24=48° meaning ∠DOB is 48°
