How many solutions does this system
have?
x + 2y = 10
2x + 8y
8y = 16
A. None
B. One
C. Infinite
Answer:
B. One
Step-by-step explanation:
There is one solution for the given system. The correct answer would be an option (B).
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
The system of equations is given in the question, as follows:
x + 2y = 10 ....(i)
2x + 8y = 16 ....(ii)
From equation (i),
x + 2y = 10
x = 10 - 2y .....(iii)
Substitute the equation x = 10 - 2y in the equation (ii), and solve for y
Then we get the value of y = -1
Substitute the equation y = -1 in the equation (iii), and solve for x
So we get the value of x = 12
Thus, there is one solution for the given system.

Help me with this pls be honest I will mark the best answer
answer:
**the answer is the picture**
i plotted the dots in the order they're in on the chart
(the x axis is the time and the y axis is the distance)
so you would plot (1,4) which is the equivalent to time=1 distance=4
next (2,8) then (3,12) and lastly (4,16)
good luck :)
hopefully, this helps

Question 10
Liam wants to treat some friends to lunch. He has $50 and knows that lunch will cost $8 per person. For how many people can Liam buy lunch?
A
Liam can buy lunch for 7 or fewer people, including himself.
B
Liam can buy lunch for 7 or more people, including himself.
C
Liam can buy lunch for 6 or fewer people, including himself.
D
Liam can buy lunch for 6 or more people, including himself.
Answer:
C
Step-by-step explanation:
8 x 6 would equal 48, which results in not having enough money to buy lunch for more people.
Answer:
the answer should be c
Step-by-step explanation:
let's do a equation for this problem.
8x = 50
/8 /8
x = 6.25
x represents the amount of friends. we divide 8 by both sides to isolate x by itself.
since the final result gives us a decimal, we have to round it to the nearest whole number. it's not possible to have a decimal amount of friends. it should be 6. it cannot be 7 if you are wondering because 7 is bigger than 6.25. there's no way there can be 7 friends when there is a limit amount of 6. therefore, the answer is c.

Sofia is a construction manager.She builds 9 house frames, each at a different site. Each frame uses 256 beams. A bundle of 400 beams delivered to each site. How many beams dose it take to build the 9 house frames? How many beams are left over at 9 house sites altogether
Answer:
2304 beams
1296 beams
Step-by-step explanation:
Total beams to be used in the 9 houses = number of frames needed for a beam x total number of house frames
9 x 256 = 2304
Total beams left over = total number of beams delivered to the 9 houses - total number of beams to be used in the 9 houses
total number of beams delivered to the 9 houses = 400 x 9 = 3600
3600 - 2304 = 1296

Answer:
the correct answer to your question is A:38
Step-by-step explanation:
this math is pretty basic, all you have to do is subtract 90-54 and you get 38.
the angle you are working with is a 90 degree angle and it gives you one part of the whole angle that is split into two parts. one part is 54 and the other is 38 making 90.

Help please..................
Answer:
C. 12
Step-by-step explanation:
To change triangle PQR to XYZ you divide by 4. This can be seen in the change from 12 to 3 on the left side of the triangle. So, you divide 20 by 4 and get 5 and then divide 16 by 4 and get 4.
12/4=3
20/4=5
16/4=4
So, you add these values together to get the perimeter of 12.
I hope this helped!
A triangle has angles that measure 43°, 7 minus 3x.° and 6x.°. Which equation can be used to find the value of x?
Answer:
The value of [tex]x[/tex] is 15.222. We need to use the following equation: [tex]9\cdot x = 137^{\circ}[/tex]
Step-by-step explanation:
From Euclidean Geometry, we know that the sum of measures of internal angles in a triangle equals 180º. Then, we can find the value of [tex]x[/tex] by this formula:
[tex]43^{\circ}+3\cdot x + 6\cdot x = 180^{\circ}[/tex] (1)
[tex]9\cdot x = 137^{\circ}[/tex]
[tex]x = 15.222[/tex]
The value of [tex]x[/tex] is 15.222.

The width of a rectangle is the length minus 6 units. The area of the rectangle is 27 units. What is the length, in units, of the rectangle?
Answer:
l = 9
Step-by-step explanation:
Create equations w = l - 6, A = 27, so A = l (l-6) so 27 = [tex]l^{2}[/tex] - 6l
so [tex]l^{2}[/tex] - 6l - 27 = 0, by factoring (l-9)(l-3) = 0 so l = 9 or l = 3 since the width can't be negative then l has to be 9 so that w = 9-6 = 3, so width = 3 and l = 9
