What would be the best method to solve
the system of equations below?
6x + 3y = 21
2x – 3y = -13

Answers

I would change 6x+3y=21 to y=-2x+7.
You can isolate the y value by subtracting the x to the other side. All the numbers have 3 in common, so you need to divide all of them by 3. I would then substitute the new equation into the 2x-3y=-13, making it 2x-3(-2x+7)=-13
You wove the equation, and once you get your x value, you needles to substitute it in the equation: y=-2x+7
The final answers will be x=1 and y=5

Elimination method is the best method to solve the system of equations below

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given system of equations

6x + 3y = 21...(1)

2x – 3y = -13...(2)

Add equations (1) and (2)

6x+3y+2x-3y=21-13

8x=8

Divide both sides by 8

x=1

Now plug in x value in equation 1

6+3y=21

Subtract 6 from both sides

3y=15

Divide both sides by 3

y=5

By Elimination method we find the values of x and y.

Hence, Elimination method is the best method to solve the system of equations below

You can text 44 words in 1 minute. Write a proportion to help you find
how many words you can type in 4 minutes. Which choice sets up the
proportion correctly and has the correct solution?

Answers

Answer:

176 words

Step-by-step explanation:

1) well we want to find the amount of words we'd be able to type in 4 minutes. so, what i did was:

44 words = x

1 minutes = 4 minutes

2) now look at how i set up the proportion, notice how i left a variable of x for the value i didn't know.

3) we also know that 1 times 4 is 4, so it'd also make sense to also multiply the numerator by 4 too!!

4) multiplying 44 by 4 would get us our answer which is 176

i belive it would be D

Step-by-step explanation:

none of the above are the correct answer. 5(x-4) + 29 would be correct which is an answer option since i see that 5x(x -4) + 9 is listed twice, i think 5(x-4)+29 is an option and there’s just a typo

the length of a boat is 10.8 m Boris buys a scale model of the boat the scale of the model is 1 to 18 work out the length of the scale model of the boat give your answer in centimetres​

Answers

Answer:

The size of the scale model is 60 centimeters.

Step-by-step explanation:

Given that the length of a boat is 10.8 m, and Boris buys a scale model of the boat whose ratio is 1 to 18, to determine the length of the scale model of the boat in centimeters the following calculation must be performed:

1m = 100cm

10.8 m = (10.8 x 100) = 1080 cm

1080/18 = X

60 = X

Therefore, the size of the scale model is 60 centimeters.

What is ¨0.83% of n is 18.26¨ (just tell me the value of n)

Answers

Answer:

N = 2,200

'Percent (%)' means 'out of one hundred':

0.83% = 0.83 'out of one hundred',

p% is read p 'percent',

0.83% = 0.83/100 = 0.83 ÷ 100

Calculate percentage:

'Percentage' is obtained by multiplying 2,200 by 0.83%

0.83% × 2,200 =

(0.83 ÷ 100) × 2,200 =

(0.83 × 2,200) ÷ 100 =

1,826 ÷ 100 =

A line includes the points (-1,0) and (-2,-9). What is its equation in slope-intercept form?​

Answers

Answer:

y = -7x -7

Step-by-step explanation:

If (-1, 0) and (-2, -9) are on the same line then that means their slope is the same. We can find slope with (y1 - y2)/(x1 - x2)

(-2 - (-9)) / (-1 - 0) = 7 / -1 = -7

then we can use the formula y = mx + b

we know that forthe first instance y = 0 and x = -1 and m(slope) = -7

0 = -7*-1 + b

0 = 7 + b

b = -7

our formula then becomes y = -7x -7
