15c=0
c=0/15 or c=0
Step-by-step explanation:
15c + 11 + 6 = 17
subtract 11 from both sides
15c + 6 = 6
subtract 6 from both sides
15c=0
divide both sides by 15
c=0/15

Find the perimeter of the figure shown to the right.
Step-by-step explanation:
that is very simple. you do understand the word "perimeter" ? it just means the distance when walking around the whole shape once.
and that clearly means to just add all side lengths.
that's it.
so, 25 + 18 + 18 + 20 + 17 = 98 ft

Justin took 55 minutes to get to school and his best friend Dwayne took 3/4 hours. How much time did they take to get to school altogether?
Answer:
100 mins or 1⅔ hrs
Step-by-step explanation:
¾ hr = ¾ × 60 mins
¾ hr = 45 mins
55 + 45 = 100
100 mins = 100 × hr/60
100 mins = 1⅔ hrs
Answer:
100 mins or 1⅔ hrs
Step-by-step explanation:
¾ hr = ¾ × 60 mins
¾ hr = 45 mins
55 + 45 = 100
100 mins = 100 × hr/60
100 mins = 1⅔ hrs
So it took them 1 2/3 hrs to get to school

What another number is divider to pi 3.14
The another number is divider to pi 22/7
The another number is divider to pi 22/7
can yallll help pls . ………
Step-by-step explanation:
so, what is the problem with the first one ?
you only need to put the specified values into the places of the variables and then simply calculate :
2×-5 + 8×6 = -10 + 48 = 38
that is how expressions, equations and functions work.
for the second, I am counting only the squares with their clear "majority" inside the line. any small parts of squares I ignore.
so,
first row : 3
second row : 5
third row : 5
fourth row : 6
fifth row : 7
sixth row : 7
seventh row : 4
eighth row : 2
total : 39
What is the equation of the line that passes through the point (-1, -7) and has a
slope of 2?
Answer:
y = 2x - 5
Explanation:
Since the slope is given as 2, we can substitute this into the equation:
y = 2x+b
Now, we can manipulate the point (-1,-7) to be in the form of a y-intercept - (0, y).
Note that a slope of 2 = 2/1, which means the rise = 2(which is added to the y) and run = 1(which is added to the x).
Adding this to our point of (-1,-7), we get:
((-1+1),(-7+2)) = (0, -5)
Therefore -5 is our y-intercept.
Now, substituting -5 into our equation, we get:
y = 2x + -5
Answer:
y=2x-5
Step-by-step explanation:
The slope-intercept form of an equation looks like y=mx+b. Where m is the slope and b is the y-intercept. The slope is already given to us, so m is 2.
To find b use the equation [tex]b=y_1-m*x_1[/tex]. So, to find the y-intercept use b=-7-(2*-1). This equals b=-5.
So, plug in the values to get the final equation y=2x-5.
Jalen earns $33 for babysitting 4 hours.
After how many hours of babysitting will Jalen have made over $500?
60.6 hours Jalen have made over $500.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Jalen earns $33 for babysitting 4 hours.
So, in one hour Jalen earns = 33/4
= $8.25
and, if Jalen have to made over $500 then she works
= 500/ 8.25
= 60.6 hours
Hence, 60.6 hours Jalen have made over $500.

Answer:
