Answer:
[1] x - 6y = 3
[2] x + 2y = 5
Graphic Representation of the Equations :
-6y + x = 3 2y + x = 5
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -2y + 5
// Plug this in for variable x in equation [1]
[1] (-2y+5) - 6y = 3
[1] - 8y = -2
// Solve equation [1] for the variable y
[1] 8y = 2
[1] y = 1/4
// By now we know this much :
x = -2y+5
y = 1/4
// Use the y value to solve for x
x = -2(1/4)+5 = 9/2
Solution :
{x,y} = {9/2,1/4}
Answer:
33433.2
Step-by-step explanation:
504 - 300 = 204
204 + 800 = 1004
100 / 3 = 33.3

You can add them out
8.3 + 3.4y - 0.5 (12y - 7)
Answer:
-2.6y + 11.8
Step-by-step explanation:
Distribute -0.5 into 12y and -7 to get to this equation, 8.3 + 3.4y - 6y + 3.5. Combine the two like terms together to get your answer which is -2.6y + 11.8.

Evaluate the expression.
131 +-5
Answer:
126
Step-by-step explanation:
131 + - 5 can either be;
131 + 5 = 136
131 - 5 = 126
The question is probably asking what is 131 plus negative 5, hence the correct equation is; 131 - 5, and the correct answer is 126.

what's the ratio for 3 stars and 7 circles
Answer: 3:7
Step-by-step explanation:
There are 3 stars for every 7 circles, thus the ratio is 3:7.
Answer:
3 : 7.
Step-by-step explanation:
For every 3 stars, there are 7 circles. If 3 stars is written first, you'll need to write 3 first in your answer, and 7 second.
This is what it would look like: 3 : 7
With ratios, you could also write,
3 to 7
or
3 / 7
But 3 : 7 is most common :)
PLEASE HELP!! WHAT IS x???
9514 1404 393
Answer:
x = 90 degrees
Step-by-step explanation:
There are several ways to go about this (as is often the case with math problems). Here, we'll use the fact that an inscribed angle is half the measure of the arc it intercepts.
arc DE = 2×∠DFE = 60°
arc EF = 2×∠ECF = 60°
arc CF = 2×∠CEF = 60°
Then arc DEC is ...
arc DEC = arc DE +arc EF +arc FC = 60° +60° +60° = 180°
Angle DBC is half the measure of this arc, so is ...
∠DBC = 180°/2 = 90° = x

Using two or more complete sentences, describe how you can find a vector parallel to B = (-2,3) .
Answer:
To find a vector parallel to B, such vector must be a scalar multiple of B.
Step-by-step explanation:
Two non-zero vectors are parallel if they are scalar multiples of one another.
A vector parallel to B must be a scalar multiple of B.
let the vector parallel to B be A, then their scalar multiple is given as;
A = kB
A = k(-2, 3)
where;
k is scalar
Thus, to find a vector parallel to B, such vector must be a scalar multiple of B.

Which of the following expressions will help him determine the length of segment BE? BE = AD BE = CD BE equals CD times AD over AE BE equals CD times AB over AC
Answer:
BE equals CD times AB over AC
Step-by-step explanation:
took the test
Answer:
BE = CD times AB/AC
Step-by-step explanation:
I took the test. And also, we know that BE + CD. so, the only one that we can eliminate from that is BE =AD. That's about all the explanation I can give you, sorry, but that is the right answer.

A school has a capacity of 965 students. If 541 students are already enrolled in the school, how many students remain? Round to the nearest ten.
Answer:
420 students
Step-by-step explanation:
965-541=424
round to the nearest ten and you get 420
i hope this helped, please mark this as brainliest! thanks
Answer:
The answer is 420

You first do the equation 965 - 541. The answer to that is 424, but when you round it to the nearest ten, the answer would be 420.
A team of seven workers started a job, which can be done in 11 days. On the morning of the fourth day, several people left the team. The rest of the team finished the job in 14 days. How many people left the team?
Let x be the number of people who left the team.
(Hint: Focus on the work left after several workers left. )
Answer:
3 people leftStep-by-step explanation:
The job can be completed by 7 people in 11 daysThe job is equivalent of 7*11 = 77 people*daysAfter 3 days, job left:
(11 - 3)*7 = 56 people*daysThis was completed by 7 - x people as x people left
Time needed was 14 days, we have new equation:
14(7 - x) = 567 - x = 4x = 7 - 4x = 3As we found, 3 people left
