Answer:  X=9-y

Step-by-step explanation:

Answer:

x = 9 - y

y = 9 - x

Step-by-step explanation:

[tex]3(x + y) = 27[/tex]

[tex]x + y = \frac{27}{3} [/tex]

[tex]x + y = 9[/tex]

[tex]x = 9 - y[/tex]

[tex]3(x + y) = 27[/tex]

[tex]x + y = \frac{27}{3} [/tex]

[tex]x + y = 9[/tex]

[tex]y= 9 - x[/tex]

Hence, the answer for x is x = 9 - y and the answer for y is y = 9 - x.

Answer:

12m + 24

Step-by-step explanation:

Using the distributive property, distribute 6 to the terms in the parentheses

6(2m + 4)

12m + 24

So, the equivalent expression is 12m + 24

Answer:

y = -28

Step-by-step explanation:

y=-4x

Let x=7

y = -4*7

y = -28

Answer:

7

Step-by-step explanation:

Given the expression

cos(3x-30°)=sin(7x+50°)

In trigonometry cosx = sin(90-x)

Hence

Cos(3x-30) = sin(90-(3x-30))

Cos (3x-30) = sin(90-3x+30)

Cos (3x-30) = sin(120-3x)

Substitute into the expression above

Sin(120-3x) = sin(7x+50)

120-3x = 7x+50

Collect like terms

-3x-7x = 50-120

-10x = -70.

x = 70/10

x = 7

Hence the value of x is 7

Answer:

8.7

Step-by-step explanation:

The answer is 8.7 because 280 centemiters converted into meters is 2.8 and 11.5-2.8=8.7

Answer:

8.0meters

Step-by-step explanation:

Given data

Area of cirlce= 201 square meters

The expression for the area is

A=πr^2

Substitute our area

201= 3.14*r^2

r^2= 201/3.14

r^2= 64.01

square both sides

r= √64.01

r= 8.0 meters

Hence the radius is 8.0meters

I had this question on a quiz. The answer is B if I remember correctly.

Answer: 29

Step-by-step explanation:

Step-by-step explanation:

Median= n+1/2 ( if n is even )

So,

10+1/2=11/2=5.5

Therefore,

135 is your second answer

Answer:

112$

Step-by-step explanation:

First, find out how much she makes per hour:

70$ in 5 hours. Divide 70 by 5.

70/5 = 14

If she makes 14$ per hour, the equation to find 8 hours is 14*8

14*8 = 112

Answer:

1 is b

2 is c

3 is b

Step-by-step explanation:

Initial co-ordinate of p = ( 2, -2)

Rule for rotation 180° about the origin

(x,y) ----> ( -x , -y )

Meaning of the rule: To find the coordinates of a point that was rotated 180° about the origin all we have to do is add negative signs in front of the x and y values of the coordinates. THE NUMBER STAYS THE SAME. THE ONLY THING THAT CHANGES IS THE SIGN

* add - to the coordinates *

- ( 2 , -2 )

-1 * 2 = -2

-1 * -2 = 2

we end up with ( -2, 2 )

Hence the answer is B

For this one a rectangle was dilated and we have to find the scale factor and the new width.

We are given the pre image width (3) and length (4) and the new image length (12)

We can find the scale factor by dividing the new image length by the pre image length ( Note that you have to use corresponding sides. Like pre image height over new image height or pre image length over new image length. etc. )

So scale factor = 12 / 4  or 3

Now to find the new image width

We can do this by multiplying the pre image width (3) by the scale factor (3)

So new image width = 3 * 3

3 * 3 = 9

Hence the width of the enlarged  print is C 9 inches

For this one we need to find x using angle rules

The angles shown are supplementary angles meaning that the sum of the two angles is 180

That being said we can create an equation to solve for x

180 = 64 + 4x + 16

Now we just solve using basic algebra

step 1 combine like terms

64 + 16 = 80

now we have 180 = 4x + 80

step 2 subtract 80 from each side

80 - 80 cancels out

180 - 80 = 100

now we have 100 = 4x

step 3 divide each side by 4

100/4 = 25

4x/4=x

we're left with x = 25

Answer:

0.3571

Step-by-step explanation:

Step 1: Start by setting it up with the divisor 14 on the left side and the dividend 5 on the right side like this:

14[tex]\sqrt{x}[/tex]5

Step 2: The divisor (14) goes into the first digit of the dividend (5), 0 times(s).

Therefore, put 0 on top:

14[tex]\sqrt{x}[/tex]0 5

Step 3: Multiply the divisor by the result in the previous step (14 x 0 =0) and write that answer below the dividend.

14 0

  [tex]\sqrt{x}[/tex]5

   0

Step 4: Subtract the result in the previous step from the first digit of the dividend (5-0 = 5) and write the answer below.

14 0

[tex]\sqrt{x}[/tex] 5

-0/5

Answer:

The person above me is correct its 9.22 meters long

Step-by-step explanation:

Answer:

(k - 4) ÷ 9

(k - 4) / 9

Step-by-step explanation:

k decreased by 4 = k - 4

quotient of k decreased by 4 and 9

= (k - 4) ÷ 9 (using division sign)

Or

= (k - 4) / 9 (as a fraction)
