Ali's dog weighs 8 times as much as her cat. Together the two pets weigh 54 pounds. How much does Ali's dog weigh

snow_tiger [21]

Ok so lets say D= Dog And C=Cat
D+C = 54

D = 8C
<span>
Now, substitute 8C for D in the first equation to get: </span>

<span>8C + C = 54 </span>

<span>Solving for the cat gives us C = 6 </span>

<span>D = 8 x 6 = 48

</span>Dog Weighs 48 Pounds

Answer:

46. <u>(3) 29</u>

47. <u>(1) y = -4x + 3</u>

48. <u>(3) 3</u>

49. <u>(3) -1/2</u>

50. <u>(4) 25x - 75</u>

Step-by-step explanation:

<u>Question 46</u>

Let red marbles be 2x + 3 and black marbles be x
2x + 3 + x = 42
3x = 39
x = 13
No. of red = 2(13) + 3 = 29 marbles
<u>(3) 29</u>

<u></u>

<u>Question 47</u>

Parallel to a line means the slope is the same
<u>(1) y = -4x + 3</u>

<u></u>

<u>Question 48</u>

For the expression to be undefined, the denominator has to be 0
x - 3 = 0
x = 3
<u>(3) 3</u>

<u></u>

<u>Question 49</u>

Slope = -4 - 1 / 4 + 6
Slope = -5/10
Slope = -1/2
<u>(3) -1/2</u>

<u></u>

<u>Question 50</u>

Total = 25x
Left 3 boxes at home = -3x = -3(25) = -75
<u>(4) 25x - 75</u>
