Answer:

Hey there!

Ratios are often converted to a number with a denominator of 100. When a ratio has a denominator of 100, it can be easily converted to a fraction or decimal.

Answer:

5 by 3

Explanation:

15 = 5 x 3

16 = 5 + 5 + 3 + 3

The dimensions of the board is either 5 by 3 square inches or 3 by 5 square inches.

The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.

here,
let the length of the board be x, and width be w,
The perimeter of the rectangle board  = 16
2 (l + w) = 16
l + w = 8
l = 8 - w

Now,
area of the board = 15
l × w = 15
(8 - w)w = 15
8w - w² = 15
w² -8w + 15 =0
(w - 3)(w -5) = 0
So,
w = 3 or 5
Now,
Lengths = 8 - 3 or 8 - 5
              =  5 or 3

Thus, the dimension of the board either 5 by 3 square inches or 3 by 5 square inches.

Answer:

a = -21

Step-by-step explanation:

-3a +2a -8 = 13

- a-8 = 13

-a -8 -13 = 0 ( the sign changes from +13 to -13 )

-8 -13 = a ( the sign of a changes from -a to + a ) -21 = a

Option D

Step-by-step explanation:

Slope intercept is:

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

m - slope

b - y-intercept.

The slope in the question is -12. The y-intercept is 1/2.

Plug in the values:

[tex]y=mx+b\rightarrow \boxed{y=-12x+\frac{1}{2}}[/tex]

Hope this helps.

Answer:

Slope-intercept form:

[tex]y = -12x + \frac{1}{2}[/tex]

Step-by-step explanation:

-Since you already have the slope and the y-intercept, all you need is to apply them to a slope-intercept form:

Slope: [tex]-12[/tex]

y-intercept: [tex]\frac{1}{2}[/tex]

-Slope-intercept equation:

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

(where [tex]m[/tex] represents the slope and [tex]b[/tex] represents the y-intercept)

-Applying to slope-intercept form:

[tex]y = -12x + \frac{1}{2}[/tex]

And were done.

An exponent of two means you square the number. So, we have -9×-9. Two negatives makes a positive, so our answer is 81.

This number is the only irrational number given.

Answer: =

6x^2−5x−6

Step-by-step explanation:  Multiply each term in one expression times each term in the other, then simplify by combining like terms.  

Here are the like terms :  =(3x+2)(2x−3)=3x(2x+3x(−3)+2(2x)+2(−3)

                                               = 6x^2−9x+4x−6

                                                     =6x2−5x−6

Answer:

y = -2x + 22

Step-by-step explanation:

You fill an aquarium with water, the water is 22 inches deep. The water evaporates at 2 inches per week. Write an equation that approximates the depth y of water in the aquarium x weeks after you fill it.

Answer: The problem above represents that of a linear function. The equation of a linear function is given by:

y = mx + b, where y is the dependent variable, x is the independent variable, m is the rate of change and b is the initial value of y when x = 0.

From the problem, the independent variable is the number of weeks and the dependent variable is the depth of water, hence y = depth of water and x = weeks after you fill it.

The rate = 2 inches per week, since it evaporates (decreases), hence m = rate of change = -2. Also, at 0 weeks (x = 0), the depth (y) = 22 inches, therefore b = 22. Using the equation for linear function, we get:

y = -2x + 22

Answer:

(BuF) = -2,-1,1,2,4,5,6,7

(BnF)= 6

Answer:

-25

Step-by-step explanation: When you multiply to negatives together you get a positive thus being shown in the problem -5 times -1 =5 then you multiply 6 times -5 and whenever you multiply a positive number by a negative you'll always get a negative number so 6 times -5 =-30 then you add 5 and -30 and you get -25. I hope this is right :D

Answer:

X= -8

Step-by-step explanation:

Subtract 6 on both sides

that leaves you with

5/5=-40/5 The 5s cancel out leaving you with -40/5 and -40 divided by 5 is -8

Answer:

x= -8

Step-by-step explanation:

5x - 6 = -46 original equation

5x = -40 added 6 to both sides

[tex]\frac{5x}{5} = \frac{-40}{5}[/tex] divide both sides by 5

x = -8 solution
