<span>If P is the midpoint of ST then ST = 2SP
4x = 2(x + 4)
4x = 2x + 8
4x - 2x = 8
2x = 8
x = 8/2
x = 4
ST = 4x = 4*4 = 16 units</span>
Answer:
Unit rate is 2.69 cups of water for 1 cup of lime juice.
Step-by-step explanation:
Rate of water (cups) per lime juice (cups) means how much water (cups) is added to 1 cup of lime juice to make limeade.
This can be calculated as,
Unit rate = Number of water (cups) / Number of lime juice (cups)
Unit rate =
Unit rate = 2.69 cups of water for 1 cup of lime juice.
<h3>18 months will pass before the two friends have the same hair length</h3>
<em><u>Solution:</u></em>
Let "x" be the number of months
Joni’s hair is 13 inches long and grows at an average rate of ⅔ in per month
Her friend Kate’s hair is 16 inches long and grows at an average rate of ½ in per month
<em><u>For two friends to have the same hair length, eqn 1 must be equal to eqn 2</u></em>
Thus 18 months will pass before the two friends have the same hair length
