Derrick Dogs sitting:
Fixed charged=$12
Hourly change=$5
Total charge=12+5x
Darlene dog sitting:
Fixed charged=$18
Hourly change=$3
Total charge= 18+3x
Find the total number of hours so that both cost are the same:
12 + 5x = 18 + 3x
5x - 3x = 18 - 12
2x = 6
x = 3

Without looking, Luke picks necklace beads from a bag of 52 beads. Half the beads are rough. The other half are smooth. There are 13 red beads, 13 blue beads, 13 green beads, and 13 black beads.
What is the theoretical probability of selecting a rough bead?
The theoretical probability of selecting a rough bead is 1/2.
Total number of beads = 52
Number of rough beads = 26
Number of smooth beads =26
What is the probability?Probability is the measurement of possibilities.
P(event) = favorable outcomes/total outcomes
P(rough) = number of rough beads/ total beads
P(rough) =26/52
P(rough) =1/2
Therefore, the theoretical probability of selecting a rough bead is 1/2.

Find the value of each variable
Answer:

Step-by-step explanation:
Two athletes Or training over a two week period to increase the number of push-ups each can do consecutively . Athlete a can do 16 push-ups to start and increase his total by each to each day. Athlete b can do 12 push-ups to start an increase he's so tall by three each day. Compare the initial values for each what does the initial value mean in the situation
Answer:
Initial values of Athlete a and b is 16 and 12 respectively. That means, Athlete a start with more push-ups as compared to athlete b
Step-by-step explanation:
Athlete a perform 16 push-ups to start and increase 1 push-up each day for 14 days
⇒ number of push-ups at the end of x days is for Athlete A is
n = number of push-ups for athlete A= 16 + x
Athlete b perform 12 push-ups to start and increase 3 push-up each day for 14 days
⇒ number of push-ups at the end of x days is for Athlete B is
m = number of push-ups for athlete B = 12 + 3x
where x is the number of days
thus, total number of athletes at the end of 14 day is
n = 16+14 = 30 push-ups for athlete A and m = 12 + 42 = 54 push-ups for athlete B at the end of 14th day
Now similarly for the initial day x = 0
thus, total number of athletes at the starting of 1st day is
n = 16+0 = 16 push-ups for athlete A and m = 12+0 =12 push-ups for athlete B at the starting of 1st day.
That means, Athlete a start with more push-ups as compared to athlete b, But at the end of 14th day Athlete b do more push-ups then athlete a
Answer: The initial value for Athlete A is greater.
Pay attention for the keyword initial value.

Answer:
3) 5/2
Step-by-step explanation:
5x - 2y = 20
(First, put it in slope intercept form: y = mx + b).
5x - 2y - 5x = 20 - 5x --> Subtracted 5x on both sides of the equation
- 2y = -5x + 20 --> Simplified
-2y/-2 = (-5x + 20)/-2 --> Divided by -2 on both sides
y = 2.5x - 10 --> Simplified
Since formula is, y = mx + b, then:
m (slope): 2.5
b (y-intercept): -10
Therefore, the answer is 3) 5/2
Hope this helped! <3
Let's solve for y.
5x − 2y = 20
Step 1: Add -5x to both sides.
5x−2y+−5x=20+−5x
−2y=−5x+20
Step 2: Divide both sides by -2.
−2y/−2 = −5x + 20/−2
y = 5/2x − 10
Answer:
y = 5/2x − 10
Slope = x, therefore, the slope = 5/2.

Shaneya purchased a membership to play basketball at her local gym. The membership costs $75 for the year, plus she pays $3 to rent equipment each time she goes. If Shaneya doesn't want to spend any more than $150 on basketball for the year, what is the maximum amount of times can she go to the gym to play?
Answer:
25
Step-by-step explanation:
Step one:
given data
We are told that Shaneya purchased a membership to play basketball at her local gym.
Costs = $75 for the year,
Rent = $3 for equipment each time she goes
Given that she has $150 to spend,
Step two:
Firstly, let us model the situation
let the total amount she has to spend be y
and the number of time she goes to the gym be x
y= 75+3x
for y= 150, let us find the value of x
150= 75+3x
150-75= 3x
75= 3x
divide both sides by 3
x= 75/3
x=25 times
The maximum amount of times is 25
