Solution

1 Simplify $\frac{225}{23}$ ×488 to $\frac{109800}{23}$ 
 $\frac{109800}{23}$ −236b=4428

Subtract $\frac{109800}{23}$ from both sides
−236b=4428− $\frac{109800}{23}$

Simplify 4428− $\frac{109800}{23}$ to − $\frac{7956}{23}$
−236b=− $\frac{7956}{23}$

Divide both sides by −236
b= - $\frac{7956}{23}$ / 236

Simplify $\frac{7956}{23}$ / 236

Simplify $\frac{7956}{23}$ to b= $\frac{7956}{23}$ ×236

Simplify to $\frac{7956}{5428}$

Simplify $\frac{7956}{5428}$ to $\frac{1989}{1357}$

B = $\frac{1989}{1357}$

Write the general equation for the circle that passes through the points (-5,0), (0.4), and (2,4).

Advocard [28]

Answer:

(x-1)^2+(y+19/8)^2=2665/64

Step-by-step explanation:

The general equation of a circle is

(x - h)^2 + (y - k)^2 = r^2

Substituting the values of the 3 given points:

(-5 - h)^2 + (0 - k)^2 = r^2

(0 - h)^2 + (4 - k)^2 = r^2

(2 - h)^2 + (4 -k)^2 = r^2

Subtracting the second equation from the first:

(-5-h)^2 - h^2 + k^2 - (4 - k)^2 = 0

25 + 10h + h^2 - h^2 + k^2 - 16 + 8k - k^2 = 0

10h + 8k = -9 ------------ (A).

Subtract the third equation for the second:

h^2 - (2 - h)^2 + 0 = 0

h^2 - 4 + 4h - h^2 = 0

4h = 4

h = 1.

Substituting for h in equation A:

10 + 8k = -9

8k = -19

k = -19/8

So r^2 = (-5-1)^2 + (0 + 19/8)^2 =

36 + 361/ 64

= 2665/64

In an election of housing society,there are 30 voters.Each of them gives the vote.Three persons X,Y and Z are standing for post

MAVERICK [17]

Answer:

Mr Y got 10 votes

Step-by-step explanation:

The election of the housing society has 30 voters. Each of them gives the vote. The three person vying for the post of secretary are X, Y and Z.

Le us calculate the votes of each contestant

Mr X

He got 2/5 of the total votes

number of votes = 2/5 × 30

number of votes = 60/5

number of votes = 12

Mr Z

He got 1/4 of the total votes

number of votes = 1/4 × 30

number of votes = 30/4

number of votes = 1/4 × 30

number of votes = 7.5 ≈ 8 votes

Mr Y

The remaining votes will be 30 - 12 - 8 = 10 votes

Therefore,

Mr Y got 10 votes

How do I solve this equation?

Keith_Richards [23]

Answer:

$y=\frac{7}{2}x+11$

Step-by-step explanation:

To solve, we need to find the y-intercept (b). In order to find the y-intercept, we can plug in the slope and the (x,y) coordinate pair given to us into the equation to solve for the y-intercept:

y=mx+b

4=(-7/-2)*-2+b

4=14/-2+b

4=-7+b

Add 7 to both sides

b=11

Therefore the equation is:

$y=\frac{7}{2}x+11$ (note that the fraction is positive since the two negatives cancel out)

M+3n+6m identify like terms

Over [174]

Looking at this we can group like terms. What are like terms? They are terms that have the same variable that we can add or subtract. In this case the like terms are 6m and m because they both have the same variable and we could add them together to get 7m.
