Answer:

-5 is the x and 10/3 is the y i think

Step-by-step explanation:

Answer:

12. x = 48

13. x = 7

Step-by-step explanation:

x/6 = 8

x = 8*6

x = 48

28 = 4x

28/4 = x

x = 7

Answer:

12) x/6 = 8

13) 28 = 4x

Answer: -x^2-2x-1

Step-by-step explanation:

Answer:

300-10w<170

subtract 300 from both sides

-10w<-130

divide by -10, because we are dividing a negative number the inequality sign changes

w>13

Answer:

The sum of two numbers is 14 and their difference is 10

Step-by-step explanation:

"2 numbers (x and y)

x+y = 14

and x-y + 10

If you each equation by positive 2, one gets 2x+2y = 28 and 2x-2y = 20

The 'y-terms' cancel out or equal zero when adding, so 4x = 48, divide by 4 on each side and x or the first number equals 12.

Plug 12 back into the equation for 'x' and subtract 12 on both sides so that y=2

The difference of 12-2=10 and the addition of 12 and 2 equals 14"

Answer:

x=8

Step-by-step explanation:

Step-by-step explanation:

To find how much 75% we multiply 100 with 75 and divide it with 100

75 × 10 ÷ 100 = 7.5

we need to do same with Noah's money

25 × 30 ÷ 100 = 7.5 Noah is correct, they have same amount.

Answer:

x = 20 ft

Area of the living room = 400 ft²

Step-by-step explanation:

From the picture attached,

Length of rug = (x - 3) ft

Width of the rug = (x - 9) ft

Area of the rectangular rug = Length × Width

                                              = (x - 3)(x - 9)

187 = (x - 3)(x -9)

187 = x² - 12x + 27

x² - 12x - 160 = 0

x² - 20x + 8x - 160 = 0

x(x - 20) + 8(x - 20) = 0

(x - 20)(x + 8) = 0

x = -8, 20

Since, measure of 'x' can't be negative, measure of x will be 20 ft.

Therefore, area of the square living room = x²

                                                                     = (20)²

                                                                     = 400 ft²

Answer: Your answer should be 8.5 π

The formula to find the length of an arc is:

m ∘ 360 ∘ 2 π r  

120 /360  2 π ( 12.6 )

120 /360  25.2 π

Simplify  120 /360  to  1 /3  and finish the other simplifying:

1 /3  25.2 π

25.2 /3 π

Since they want the answer expressed by  π ,  8.5π  is the answer.

Answer:

12 feet

Step-by-step explanation:

use the pythagorean theorem to figure out what the hypotenuse is

3.5^2+3.5^2=x^2

12.25+12.25=x^2

25=x^2

x=5

now that you know the hypotenuse, you can find the perimeter by adding up all the sides

3.5+3.5+5=12

Answer:

Subtract 3 from 8, then divide 75 by 5.

Step-by-step explanation:

First, subtract 3 from 8 since she finished 3 already.

8-3=5

This means that Sumi has 5 more pots to make. Since she has 75 minutes left, and she wants to finish all the pots in the same amount of time, we can divide 75 by 5.

75/5=15

Sumi should finish each pot in 15 minutes.

Answer:

3

Step-by-step explanation:

if you can't use calculator, you must know that after a number being square root, it MUST be in positive

for the negative answer will be false

so for the rest of the answer you need to try it

3² = 9 < 10 so it's true

4² =16 > 10 so it's false

the only answer is 3

Answer:

D) x = 8

Step-by-step explanation:

The information given states that ABCD is similar to RSTU.

Line BC is similar to Line ST. ST is 2 times larger that BC.

Line AB is similar to Line RS. RS must be 2 times larger than AB as well, so multiply 4 x 2 to get x = 8.

Answer:

-1/3

Step-by-step explanation:

Slope Formula = (y2-y1) over (x2-x1)

(1-2) over (0- -3)

(-1) over (0+3)

-1 over 3

-1/3

Hope this helps. Have a nice day you amazing bean child.

Answer:

y = -x +2

Step-by-step explanation:

First let's find the slope.

(-1,3) and (4,-2)

3 - -2/ -1 - 4 = 5/-5 = -1

Slope = -1

Now let's use slope intercept form:

y1-y2=m(x1-x2)

Let's plug in our slope for m.

y1-y2= -1 (x1-x2)

And now let's substitute y2 and x2 for one of our points, I'll use (4,-2)

y1+2 = -1(x1- 4)

y= -x + 4 -2

y = -x +2
