Answer:

  x = 4c-3d

Step-by-step explanation:

Cross multiply, separate variables terms and constant terms.

  [tex]3(x-d)=4(x-c)\\\\3x-3d=4x-4c\\\\4c-3d=x\qquad\text{add $4c-3x$}\\\\\boxed{x=4c-3d}[/tex]

Answer:

A (-4,9) B (-4,11) C (-6,10)

Last option is correct

Step-by-step explanation:

To rotate the vertices about the given point at 90 degrees, we follow the procedures below;

Mathematically, if we have a point (m,n) and we want to rotate it 90 degrees about a given point (x,y). Then the new transformation point will be;

( -(n-y) + x , (m-x) + y)

Let’s now take the points individually;

(3,2 ) about (-4,2)

This becomes

(-(2-2) + (-4), (3+4) + 2) = (-4 , 9)

The point (5,2) about (-4,2) becomes

(-(2-2) + -4, (5 + 4) + 2 )= (-4, 11)

and lastly

The point (4,4) about (-4,2) becomes

(-(4-2) + (-4), (4 + 4) + 2) = (-6, 10)

7/4 ÷ (3/2)

=7/4 × (2/3)

=(7×2)/(4×3)

=14/12

=(14÷2)/(12÷2)

=7/6

=1 1/6

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Monthly Payment (PMT) = 200 at the end of each period

interest rate = 2.9% = 0.029/12 = 0.0024166

Period (n) = 43 years x 12 = 516

Using the future value(FV) of an ordinary annuity:

FV = PMT[(1 + r)^n - 1] / r

FV = 200[(1 + 0.0024166)^516 - 1] / 0.0024166

FV = 200[(1.0024166)^516 - 1] / 0.0024166

FV = 200(2.4745372) / 0.0024166

FV = 204,794.93

Amount which will be in saving plan towards retirement = $204,794.93

Interest amount :

$204,794.93 - total monthly deposits

$204,794.93 - (200 * 516)

$204,794.93 - $103,200

= $101,594.93

Did this help??

Step-by-step explanation:

a.) 5x = m

5x = you and four friends.

m = money for food

b.) Plug in

5(5.25) = m

26.25 = m

Answer:

m = 16 2/3

Step-by-step explanation:

Let m = maries age

3m = 50

Divide by 3

3m/3 = 50/3

m = 16 2/3

Answer:

Marie's age is 16.7 years

Step-by-step explanation:

3 times Marie's age is equal to 50, so you divide 50 by 3.

50 ÷ 3 = 16.6666666 repeating, round it to 16.7

Marie's age is 16.7 years.

Check: 3 x 16.7 = 50.1 so you round it to 50.

Answer:

$0. 25

Step-by-step explanation:

2. 95 ÷ 12 = 0.24583333

Round the number and you would get

0. 25

Answer:

D. $0.25

Step-by-step explanation:

the whole pack costs $2.95 and there are 12 sticks, so you divide the total cost ($2.95) by the amount of sticks (12) and get the answer $0.2458, or $0.25 rounded up. :)

Answer:

The y-intercept is -2

Step-by-step explanation:

Here, we want to find the y-intercept of the function that passes through the given points

The first thing to do here is to get the coordinates of the needed point;

That would be ; (12,2) and (15,3)

It is just like writing f(x) = a ; x would

be x-value while a will be the y-value

The equation of the line passing through the points will be

y = mx + b

where b represents the y-intercept

Let us start by looking at the slope m

m = (y2-y1)/(x2-x1)

m = (3-2)/(15-12) = 1/3

So the line would be;

y = x/3 + b

now to get b, select any of the points, input the x value and the y value

2 = 12/3 + b

2 = 4 + b

b = 2-4

b = -2

Have a Spoopy Halloween lol its 9x-3

Step-by-step explanation:

(6x+1/2)+(3x-3 1/2)

= 6x+3x-3 1/2+1/2

= 9x-3

Answer:

[tex]9x - \frac{6}{2} [/tex]

Step-by-step explanation:

[tex](6x+1/2)+(3x-3 \: 1/2) \to \\ ( 6x + \frac{1}{2} ) +( 3x - 3 \frac{1}{2} ) \to \\ 9x + \frac{1}{2} - \frac{7}{2} \to \\ 9x - \frac{6}{2} [/tex]

Answer:

(a) [tex]x= \frac 2 3\div \frac 1 6[/tex]

(b) [tex]x= \frac 2 3\times \frac 6 1[/tex]

(c) 4 pounds

Step-by-step explanation:

Let the capacity of the container is [tex]x[/tex].

The container has coffee which is 1/6 of the capacity of the container and the amount of coffee is 2/3 pounds.

So, 1/6 of the capacity of the container has 2/3 pound of coffee, i.e

[tex]\frac 1 6 \times x = \frac 2 3\cdots(i)[/tex]

(a) From the equation (i), the required division expression for the capacity of the box, x, is

[tex]x= \frac 2 3\div \frac 1 6[/tex]

(b) The division expression can be changed to multiplication expression by interchanging the numerator and the denominator of the divisor. So, from part (a), the required multiplication expression for the capacity of the box, x, is

[tex]x= \frac 2 3\times \frac 6 1\cdots(ii)[/tex]

(c) From equation (ii), the capacity of the box is

[tex]x= \frac 2 3\times 6= 4[/tex] pounds.

i wanna go back to school

Answer: A6/ 2/3= 9

Step-by-step explanation:

We know that one tile is 2/3 ft long and we want to cover 6 ft (which is the given measure of the back of the shower).

To know the number of tiles needed, we will simply do cross multiplication as follows:

1 tile ...............> 2/3 ft

?? tiles ...........> 6 ft

Number of tiles = (6*1) / (2/3)

Number of tiles = 6 / (2/3)

Number of tiles = 9 tiles

Answer:

A). 6 ÷ 2/3 = 9

The second graph ( one with the coordinates (3,1) and (6,3))

Step-by-step explanation:

Answer:

The answer is B.

Step-by-step explanation:

Answer:

y = 15.9

Step-by-step explanation:

y = 3 - 4.3x

y = 3 - 4.3(-3)

y = 3 + 12.9

y = 15.9

Answer:

Step-by-step explanation:

y=3-4.3x

y=3-(4.3*3)

y=3-12.9

y=-9.9

y = 3x + 0 is the answer I believe.

Answer:

67 and -1

Step-by-step explanation:

You always multiply first so its 7+64-4 and that becomes 67

You have to distribute first so the problem would be 5-21+15   which is -1
