Jerry lives 3 1/2 miles away from Jake. Jerry and Jake decided to meet half between their houses and then walk to the park together. The park is located 3/5 mile from the halfway point. How far did Jerry walk in all to get to the park?
Answer: Jerry walked 2 7/20 miles to get to the park
Step-by-step explanation:
1/2 of 3 1/2
1/2 of 7/2 = 7/4
7/4 + 3/5
Find the LCM of the denominator
LCM of 4 and 5 = 20
35/20 + 12/20 = 47/20 = 2 7/20

Isaiah is working two summer jobs, making $16 per hour tutoring and $10 per hour clearing tables. Isaiah must earn at least $110 this week. Write an inequality that would represent the possible values for the number of hours tutoring, tt, and the number of hours clearing tables, cc, that Isaiah can work in a given week.
Answer:
16t + 10c > 110
Step-by-step explanation:
Cost of tutoring per hour = $16
So, cost of tutoring t hours = $16t
Cost of clearing tables per hour = $10
So, cost of clearing tables c hours = $10c
Since, Isaiah must earn at least $110 this week.
Therefore, the required inequality will be given as:
16t + 10c > 110
An arithmetic sequence has this explicit formula: an = 14 + (n - 1)3. What is the recursive formula?
Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 3 with a₁ = 14
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference, then
[tex]a_{n}[/tex] = 14 + (n - 1)3
has a₁ = 14 and d = 3
A recursive formula allows a term in the sequence to be found by adding d to the previous term, thus recursive formula is
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 3 , with a₁ = 14

Answer:
126
Step-by-step explanation:
70
+ 56
126
If Ed and Whitney are 70 feet apart, then Candice and Ed are 42 feet apart.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given that the Candice is deep-sea diving with two friends
Whitney is exploring a coral reef 56 feet in front of Candice
The distance between Whitney and Candice is 56 feet.
Ed is floating on the surface directly above Candice.
Ed and Whitney are 70 feet apart, we need to find the distance between Ed and candice.
By using Pythagoras theorem we can find this.
70²=56²+x²
4900=3136+x²
Subtract 3136 from both sides
4900-3136=x²
x²=1764
Take square root on both sides
x=42
Hence, If Ed and Whitney are 70 feet apart, then Candice and Ed are 42 feet apart.

Answer:
b) true for one value
Explanation:
If you solve for x, there is only one value of x
Answer:
(b)
Step-by-step explanation:
9(x - 2) = 7x + 5 ← distribute left side
9x - 18 = 7x + 5 ( subtract 7x from both sides )
2x - 18 = 5 ( add 18 to both sides )
2x = 23 ( divide both sides by 2 )
x = [tex]\frac{23}{2}[/tex]
