Answer:

49

Step-by-step explanation:

3x+10+6x-20+x+60=10x+50

10x+50=180

10x=130

x=13

A=3*13+10=49

Multiply two and five-eighths negative two and three-fifths . negative six and thirty-three fortieths negative four and three-ei
OLga [1]

The <em><u>correct answer</u></em> is:

negative six and thirty-three fortieths

Explanation:

To multiply (2 5/8)(-2 3/5), we first change each mixed number to an improper fraction.  To do this, we multiply each whole number by the denominator and add the numerator:

(2*8)+5 = 16+5 = 21; this makes 2 5/8 = 21/8

(2*5)+3 = 10+3 = 13; this makes -2 3/5 = -13/5

This gives us

(21/8)(-13/5) = (21*-13)/(8*5) = -273/40

40 will go into 273 6 times; this gives us the number -6.  There is then 270-240 = 33 left over; this gives us 33/40, and a total of -6 33/40.

Point Q is the image of Q(4-6) under a translation by 1 unit to the right
inessss [21]

Answer:

The  image of Q(4,-6) under a translation by 1 unit to the right then the new coordinate point R( 5 , -6)

Step-by-step explanation:

Explanation:-

Given image Q( 4, -6)

Type of transformation                                    change to co-ordinate point

a) Horizontal translation left

'C' units                                                                        (x, y)  ⇒   (x- c, y)

b) Horizontal translation right 'C' units                   (x, y)⇒( x +c ,y )

c) vertical translation up 'd' units                            (x, y)⇒( x  ,y + d )

d)  vertical translation down 'd' units                        (x, y)⇒( x  ,y - d )

     

Now we will use Horizontal translation right 'C' units    

image of Q(4-6) under a translation by 1 unit to the right

Q( 4 , -6)   ⇒ The new image R( 4+1 ,-6)

The  image of Q(4-6) under a translation by 1 unit to the right then the new coordinate point R( 5 , -6)
