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>
Answer:
C. 375
Step-by-step explanation:
250/20 = 12.5
12.5 x 30 = 375
Answer:
2√6
Step-by-step explanation:
√24
√24 can be split into √8 and √3 because 8x3=24
√8 can be split into √4 and √2, and √4 equals 2.
√3 times √2 is √6
2√6
6/6. you will always get a number less that seven.
The amount loaned at 8% is $4800.
The amount loaned at 18% is $6,200.
<h3>What are the linear equations that represent the question?</h3>
a + b - 11,000 equation 1
0.08a + 0.18b = 1500 equation 2
Where:
a = amount loaned at 8%
b = amount loaned at 18%
<h3>How much was loaned at 8 and 18%?</h3>
Multiply equation 1 by 0.08
0.08a + 0.08b = 880 equation 3
Subtract equation 3 from equation 2
0.10b = 620
b = 620 / .10
b = $6200
a = 11,000 - 6200 = $4800
