Somebody help me with this question, please!
Two lines, A and B, are represented by the following equations: Line A: 3x + 3y = 12 Line B: x + y = 4 Which statement is true about the solution to the set of equations? (4 points)
Select one:
A. It is (12, 4).
B. There are infinitely many solutions.
C. It is (4, 12).
D. There is no solution.
Answer:
it is definitely the option of C
Answer:
b infinite solutions
Step-by-step explanation:
3x+3y= 12
when divided by three you get
x+y=4
This can have many solutions such as
x=1 y=3
x=1.5 y=2.5
x=3.99
y=0.01
etc
The wholesale price for a chair is $124. A certain furniture store marks up the wholesale price by 16%. Find the price of the chair in the furniture store.
Round your answer to the nearest cent, as necessary.
Answer:
$143.84
Step-by-step explanation:
Given the following question:
Initial price of the chair was $124....
Marked up 16% (which means the price has increased by 16%)
Find the new price of the chair...
In order to find the answer, we find 16% of a given number in till it equals 124 which was the initial price.
[tex]\frac{143.84-124}{124} \times100=143.84-124=19.84\div124=0.16\times100=16[/tex]
16% of 143.84 is 124
143.84 is already rounded to the nearest cent
Which means the new price of the chair is "$143.84"
Hope this helps.

What is the missing Angle
Answer:
31°
Step-by-step explanation:
As there is a z shape: we can deduce that:
5x+12+x=180
So now we solve this to get x
6x=180-12
6x=168
x=168÷6
x=31
31°
Answer:31

can some help i cant figure this out
Answer:
240cm²
Step-by-step explanation:
area of a triangle:
½ x b x h
= ½ x 6 x 4
= 3 x 4
= 12.
since there are 8 of the same triangles, they will all have the same area. so to work out the total area of a triangles, we times the area of one triangle by the 8 triangles in the polygon.
12 x 8 = 96.
for the square in the middle:
area of a square = length x width
area of a square = 12 x 12 = 144.
all we need to do is add these two totals together.
144 + 96 =240cm².
we use the units cm², because we have been multiplying xcm x ycm which can be simplified to cm² :)

Answer:
Not completely sure about A but I know the rest!
Explanation:
a) burritos are the independent variable because it is labeled as x. X will always be the independent variable. The reason I am confused is because all throughout my learning I was told "time" will always be independent and it had always proved to be true. I would just go with burritos though.
b) linear function is y=0.75x, with 0.75 being the slope representing the amount of time taken to make x amount of burritos. I see you already did most of the work! You just have to remember that to find slope (or m), that you do change in y/change in x.
c) when graphing, draw a point at the origin, (0,0). Then count 0.75 units up, and move 1 unit to the right. Your line should be from left to right going "upward".
d) your answer for d is correct

Marie drives for___________________hours.
Answer:
Marie drives for 3 hours.
Step-by-step explanation:
Equation d = rx
d = distance traveled
r = rate of speed
x = # of hours driven
35x = 105
x = 105 / 35
x = 3
Marie drives for 3 hours.
Solve each inequality. Graph the solution on a on a number line.
p-7/12>3/10
Answer:
so to solve an inequality you just treat the inequaltity sign like an equals sign except if you multiply by negative 1 you flip the direction of the sign.
p-7/12>3/10
add 7/12 to both sides
p>7/12+3/10
p>35/60+18/60
p>53/60
so if you had to graph this on a number line you would have an open circle on 53/60 and an arrow coming off pointing to the right

Enter your answer as a decimal in the box.
3 and 7.5 are the box lengths
Answer:
2.5
Step-by-step explanation:
If you multiply 3 by 2.5, you get 7.5. I'm assuming the number 3 is the original and the 7.5 is the result? If so, this answer is definitely correct. Hope that helps :)
Javier walks up to a tank of water that can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Javier first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water.
At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.
How many more minutes will it take for the tank to drain completely? Explain or show your reasoning.
How many minutes before Javier arrived was the water tank completely full? Explain or show your reasoning.
Answer:1) Gallons per minute change is -2/3 gallons per minute since it decreases by 2 gallons in 3 minutes
2) we have 5 gallons and lose 2/3 gallons per minute
(2/3 gal/minute)(x minutes) = 5 gallons
x = 5(3/2) = 15/2 = 7.5 minutes to drain the other 5 gallons
3) There were 10 gallons when the tank is full
That is 3 gallons more than the 7 gals there when Jada arrived.
(2/3)(x) = 3
x = 3(3/2) = 9/2 = 4 1/2 minutes
The tank was full 4 1/2 minutes before Jada arrived.

simplify: -2(4 -3y) + 5 (4y - 1)
- 13 + 26y
Answer:
1 is 10x - 8,( 2 is 14n + 15,( 3 is 20y +11,( 4 is -5x - 17,( 5 26y - 13
Step-by-step explanation:
1 you use distributive property so 2 * 5x and 2 * 4, 2 you use distributive property again and add 10n and 4n, 3 you use distributive property and since you multiplying with 2 negatives it makes them positive, 4 you use distributive property and subtracting -15 by two becomes -17, 5 you use distributive property on both and add the rest together.

Trapezoid WXYZ is shown on the coordinate grid.
Trapezoid WXYZ is dilated with the origin as the center of dilation using the rule (x, y) --> (4x, 4y) to create Trapezoid W'X'Y'Z'.
Which statement is TRUE?
A. Trapezoid W'X'Y'Z' is smaller than Trapezoid WXYZ because the scale factor is less than one.
B. Trapezoid W'X'Y'Z' is smaller than Trapezoid WXYZ because the scale factor is greater than one.
C. Trapezoid W'X'Y'Z' is larger than Trapezoid WXYZ because the scale factor is less than one.
D. Trapezoid W'X'Y'Z' is larger than Trapezoid WXYZ because the scale factor is greater than one.
Answer:
D
Step-by-step explanation:
in the question the scale factor is 4 so that means it is a dilation (getting larger) because the scale factor is >1
