Answer:

RT = 86

Step-by-step explanation:

23x - 6 = 2(15x - 17)

23x - 6 = 30x - 34

23x - 30x = - 34 + 6

-7x = -28 |÷(-7)

x = 4

RT = 23x - 6 = 23 × 4 - 6 = 92 - 6 = 86

Answer:

Adding 7 to both sides of the equal sign

Answer:

Please see the explanation.

Step-by-step explanation:

As we know that the slope-intercept form of the equation is

[tex]y=mx+b[/tex]

Now, comparing the given equations with the slope-intercept form

a) y = 4/5x + 3

Here:

m = 4/5

Therefore, the slope of the equation y = 4/5x + 3 is: m = 4/5

b) y = -x + 1

Here:

m = -1

Therefore, the slope of the equation y = -x + 1 is: m = -1

b) y = 2x

Here:

m = 2

y-intercept = b = 0       ∵ y = mx+b here b is the y-intercept

Therefore, the slope of the equation y = 2x is:

m = 2 and

y-intercept = b = 0

Answer:

A 2-column table with 6 rows. Column 1 is labeled Tables with entries 1, 2, 3, 4, 5, 6. Column 2 is labeled Chairs with entries 6, 12, 18, 24, 30, 36.

Rachel is setting up for her birthday. Rachel wants to put the same number of chairs around each table. How many chairs will Rachel place around each table at her birthday party?

Answer:

-1/5

Step-by-step explanation:

6/5=-18/x

6/5×-1/18=x

-1/15=x

Answer:

-15

Step-by-step explanation:

[tex]\frac{6}{5} = \frac{-18}{x}[/tex]

cross multiply

6 × x = -18 × 5

6x = -90

x = -90/6

x = -15

Change 53% to a decimal. Doing so, we get 0.53.

Let n = the number we are looking for.

The word "is" in math means to use the equal sign.

135 = 0.53n

Divide both sides by 0.53.

135/0.53 = 0.53n/0.53

254.7169811321 = n

Rounding to the nearest tenths, we get

n = 254.72

Done!

Ok so the problem is what are we looking for how many miles was traveled? or what

Answer:

The answer is:

[tex]Q' = (-3, 3)\\\\R' = (-5, -3)\\\\S' = (-2, -2)\\\\T' = (0, 1)\\\\[/tex]

Step-by-step explanation:

All vertices of its quadrilateral were co-ordinated;  

[tex]T(-2, 1), \ Q(1, 3), \ S(0, -2), \ R(3, -3)[/tex] Therefore, we first undertake the operation correct: [tex]T(2, 0) \ QRST[/tex], there;

[tex]T(2, 0) \ QRST[/tex] [tex]\to T(-2 + 2, 1), \ Q(1 + 2, 3), \ S(0 + 2, -2), \ R(3 + 2, -3)[/tex]

[tex]T(2, 0) \ QRST[/tex][tex]\to T(0, 1), \ Q(3, 3), \ S(2, -2), \ R(5, -3)[/tex]

A preimage (x, y) will be the image in the next phase R-y-axis reflecting mostly on the y-axis (-x, y)  and we've got it;  

R y-axis [tex](T(0, 1), \ Q(3, 3), \ S(2, -2), \ R(5, -3)) = \ T'(0, 1), \ Q'(-3, 3), \ S'(-2, -2), \ R'(-5, -3)[/tex]From which we get [tex](Ry-axis \ T(2, 0)) \ (QRST = T'(0, 1), \ Q'(-3, 3), \ S'(-2, -2),\ R'(-5,-3).[/tex]

Answer:

There are 12 quarters and 16 dimes

Step-by-step explanation:

Firstly, we need to know that a quarter is worth $0.25 while a dime is worth $0.10

There are 4 more dimes than quarters;

So if there are x quarters, there are x + 4 dimes

From the question we can get;

0.25(x) + 0.1(x + 4) = 4.6

0.25x + 0.1x + 0.4 = 4.6

0.35x = 4.6-0.4

0.35x = 4.2

x = 4.2/0.35

x = 12

X + 4 = 12 + 4 = 16

Answer:

She must ride 4 or more times

Step-by-step explanation:

3t+ 10 ≥22

Subtract 10 from each side

3t+ 10-10 ≥22-10

3t ≥12

Divide each side by 3

3t/3 ≥12/3

t ≥4

She must ride 4 or more times

Let, number of small and big pumpkin are x and y.

So, mathematical equation is given by :

x + y = 29    ...1)

3x + 5y = 105     ...2)

Putting value of x from equation 1 to equation 2, we get :

[tex]3(29-y ) +5y=105\\\\2y = 18\\\\y = 9[/tex]

So, x = 20

Therefore, number of small and large pumpkins are 20 and 9 respectively.

Hence, this is the required solution.
