Answer:
Parallel line slope = - 1/2
Perpendicular line slope = 2
Step-by-step explanation:
7x + 5 = 5x + 11
2x + 5 = 11
2x = 6
x = 3
7(3) + 5
21 + 5 = 26
Answer:
8 Weeks
Step-by-step explanation:
First let's collect the given data:
• <u>Class A:</u>
- Starts at 8 cm
- grows at 3.5 cm/week
• <u>Class B:</u>
- Starts at 10cm
- grows at 3.25 cm/week
Class B's plant starts out 2 cm taller and Class A's plant grows 1/4 cm faster. So, to find when these two will be at an equal height, divide 2 cm by 1/4.
2 ÷ 1/4 =
2 × 4/1 =
2 × 4 =
8
It will take 8 weeks for the plants to be at an equal height.
Answer:
12
Step-by-step explanation:
This question means 3/(1/4). The rule for division of fractions is invert the denominator and multiply. 3/(1/4) = 3 * 4 = 12. Another way to think of it is to imagine you have 3 pies each divided into quarters.
