A baker at a bakery had made 20 pastries after 1 hour of work. After 8 hours, he had made 83 pastries. M= ?
9514 1404 393
Answer:
9 pastries per hour
Step-by-step explanation:
In the 7 hours after the first, the baker made 83 -20 = 63 more pastries. That rate is ...
(63 pastries)/(7 hours) = 9 pastries per hour
_____
Additional comment
We have chosen to interpret the question as asking for the slope of a line on a graph of pastries vs. hours. Such a graph would show you the baker started with 11 pastries already made, so didn't actually make 20 in the first hour.

Answer:
equation of line
x-2y=8
Step-by-step explanation:
equation of line in slope intercept form

in in the previous activity you solved a system of equations representing the carnival admissions using the elimination method in this activity you will solve the same system using substitution then you'll compare your solution with the solution you obtained in the previous activity by using the elimination method
the two equations from the previous activity are given below
k + a = 500 (1)
3K + 10A equals 3,600 (2)
which equation has at least one of its variables with a 1 as it's coefficient?
Answer:
The value of a=300 and value of k=200
If you solve the above system of equations by elimination method, you will get the same values of a and k.
In Equation 1 [tex]k+a=500[/tex] both variables k has 1 as their coefficient.
Step-by-step explanation:
We need to solve the system of equations using substitution method
The equation are:
[tex]k + a = 500--eq(1)\\3k + 10a = 3,600 --eq(2)[/tex]
For substitution method, we find value of k from equation 1 and put in equation 2
[tex]From \ eq(1) \ we \ get\\k=500-a[/tex]
Putting it in eq(2)
[tex]3k+10a=3600\\Put \ k=500-a\\3(500-a)+10a=3600\\1500-3a+10a=3600\\7a=3600-1500\\7a=2100\\a=\frac{2100}{7}\\a=300[/tex]
So, we get value of a = 300
Now finding value of k by putting value of a in equation [tex]k=500-a[/tex]
[tex]k=500-a\\Putting \ a \ =500\\k=500-300\\k=200[/tex]
So, we get value of k =200
The value of a=300 and value of k=200
If you solve the above system of equations by elimination method, you will get the same values of a and k.
In Equation 1 [tex]k+a=500[/tex] both variables k has 1 as their coefficient.
Dominic goes jogging every morning. If m represents the number of miles he jogs each day, which expression represents the total number of miles he jogs in a week?
a. 7m
b. 7+m
c. 7-m
d. 7/m
Answer:
The answer is a: 7m
Step-by-step explanation:
The amount of miles he jogs is m, and there are 7 days in a week. Multiply that, and you'll have your answer.
If Peter pays $84 to buy a watch after a discount of 30%, find the original price of the watch
(Original price) - 0.30p = 84
Let p = Original Price of the watch
p - 0.30p = 84
0.70p = 84
p = 84 ÷ 0.70
p = 120
The original price of the watch is $120.
Answer:
The original price was $120.
Step-by-step explanation:
Let the original price of the watch be w.
Then the discount is 0.30w and the discounted price is (1-0.30)w, or 0.70w.
Writing an equation in w, we get 0.70w = $84.
Solving this for w, we divide both sides by 0.70:
w = (84)/0.70 = $120
The original price was $120.

find the difference (10j-7)-(9j-2)
Answer:
j-9
Step-by-step explanation:
combine like factors
subtract nine from both sides, j-7=-2
subtract 2 from both sides, -2-7=-9, j-9
Answer:
j-5
Step-by-step explanation:
(10j - 7) -(9j - 2) = x
(10j - 7) = x + (9j - 2)
10j - 7 = x + 9j - 2
10j - 9j -7 + 2 = x
x = ( j - 5)
