Answer:
- a) j+c=310; j-c=40
- b) (j, c) = (175, 135)
- see attached
- Jose earned $175; Camden earned $135
Step-by-step explanation:
Let j and c represent Jose's and Camden's earnings, respectively.
(a) One equation can be written for the total; another for the difference:
j + c = 310 . . . . their total earnings
j - c = 40 . . . . . the difference in their earnings
__
(b) It is convenient to add these two equations to eliminate c:
(j +c) +(j -c) = (310) +(40)
2j = 350
j = 175
Then c can be found as ...
c = j -40 = 175 -40 = 135
The solution is (j, c) = (175, 135).
__
(c) Using x for j, and y for c, we can use Desmos to graph the equations. The result is attached.
__
(d) Jose earned $175 over the summer; Camden earned $135.

Answer:
50
Step-by-step explanation:
Well, we would first have to add the amount of cookies he gives to ONE person, and then multiply that by 19 since he has 19 employees. Since he gave 6 chocolate chip and 2 peanut butter cookies, we'd have to add 6 + 2 which equals 8. Now that we know Frank gave 8 cookies per person, we have to calculate how many cookies he gave to ALL his employees, by multiplying 8 by the total amount of employees, (19), so now we'd do 8 times 19 = 152, so that means he gave 152 cookies to all his employees. c:
Answer:
842 grams
Step-by-step explanation:
One cake consists of 421/6 grams of chocolate.
Since Sally wants to give 1 cake to 12 friends, we multiply 421/6 and 12.
To make 12 cakes, she needs 842 grams of chocolate.
