Answer: 33\frac{3}{4}\ pounds

Step-by-step explanation:

The weight of Ana's dog at the time of its birth= 5\frac{5}{8}\ pounds=\frac{45}{8}\ pounds

By age 4, the dog weighed 6 times as much.

Now, the weight of Ana’s dog at age 4 =6\times\frac{45}{8}=\frac{45\times3}{4}=\frac{135}{4}\ pounds

Since, \frac{135}{4}=33\frac{3}{4}

The weight of Ana’s dog at age 4 = 33\frac{3}{4}\ pounds

Answer:

1/2a = -5

a = (-5 x 2) : 1

a = -10

8 - b = 9,5

b = 8 - 9,5

b = -1,25

0,1 = -10c

c = 0,1 : -10

c = -0,01

I hope it's helpful.

Answer:

  r = 1/9

Step-by-step explanation:

First of all, solve the equation for r:

  y = rx

  y/x = r . . . . . . . divide by x

__

Since r is a constant, it will be the same for any corresponding pairs of x and y. It is convenient to choose both x and y as integers, as in the third table entry.

  r = y/x = 5/45

  r = 1/9 . . . . . . . . . reduced fraction

_____

<em>Additional comment</em>

It is not a bad idea to check to see that this works with other values of x and y. For the first line of the table, we have x = 11:

  y = rx = (1/9)(11) = 11/9 = 1 2/9 . . . . matches the table value

X+y=4<br> X-3y=12<br> Graph?
AlekseyPX
I'll solve it algebraically


x+y=4
x-3y=12

multiply first equatoin by -1 and add to second

-x-y=-4
<u>x-3y=12 +</u>
0x-4y=8


-4y=8
divide both sides by -4
y=-2

sub back

x+y=4
x+-2=4
add 2 to both sides
x=6

x=6
y=-2
(6,-2)
