Answer: x = 7y.

Step-by-step explanation: There is direct variation between the number of toddlers and the number of teachers. We know this because when one increases, the other would as well. We can write the equation of direct variation as x = 7y.

Answer:

a= 11.55

Step-by-step explanation:

If the answer is 8.45, then the variable equals the difference of 20 minus the answer, 8.45

Answer:

3*sqrt13

Step-by-step explanation:

You search for hypotenuse

Squared hypotenusw is equal to 6^2+9^2= 36+81=117

Hypotenuse is equal to sqrt117= sqrt9*sqrt13= 3*sqrt13

The value of the given expression is - 53.55

[tex]5 \frac{1}{4}( - 10.2) \\ [/tex]

The bracket implies multiplication :

Hence,

[tex]5 \frac{1}{4}( - 10.2) \\ [/tex] = [tex]5 \frac{1}{4}\times - 10.2

Converting the fraction to improper :

[tex] \frac{21}{4} \times - 10.2[/tex]

Then, to decimal :

[tex]5.25 \times - 10.2 = - 53.55[/tex]

Hence, the value of the expression is - 53.55

Answer:

AB=1

Step-by-step explanation:

Colinear means all points are on the same line. We need to find the measure of AB.

Using the segment addition postulate,

ab+bc=ac

Subsitue this for our known values

[tex]2x + 15 + 9 = x + 17[/tex]

Solve for x

[tex]2x + 24 = x + 17[/tex]

[tex]x + 24 = 17[/tex]

[tex]x = - 7[/tex]

Plug this in for AB

[tex]2( - 7) + 15 = 1[/tex]

Step-by-step explanation:

proper an answer cannot be written if the three circles touch Each Other as well as the the sides of the rectangle it means that rectangles length and breadth are made by attaching to circles together which means that length and breadth of the rectangle are equal therefore length is equal to diameter of one circle into two that is 8 therefore length and breadth of the rectangle are 8 each other for exact area of rectangle is 8 x 8 = 64

Step-by-step explanation: Though the times might be confusing, the problem itself is simple addition- if the temperature rises, or goes up, by a certain number, in this case three, you're just going to add that number to the initial number, two.

Step-by-step explanation:

There are several methods to solve equations of the type AX = XB. These type of equations occur in domains like robotics, for which solutions have been proposed like the Tsai and Lenz method [IEEE 1987], for example. 1) I feel solving the equation XA = XB is not the same as solving the known form AX = XB. Am I right? 2) Neither can it be solved like the Sylvester equation, because even that requires AX+XB=CAX+XB=C form. What i have is XA=XBXA=XB, a redundant set of equations. That is,

A1.XA2.XAn.X=X.B1=X.B2⋮=X.BnA1.X=X.B1A2.X=X.B2⋮An.X=X.Bn

If i am correct, these could be rewritten into another form like AX=BXAX=BX. Should i rewrite the equation and try to solve this problem using any other existing methods?
