X = large boxes and y = small boxes
x + y = 70.....x = 70 - y
60x + 65y = 4300
60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs
x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs
Answer:
48
Step-by-step explanation:
The silmutenous equations
2/3x + 1/2y = 56
X=y
Answer:
The approximate solution to the system is 
.
Step-by-step explanation:
To solve the system of equations 
you must:
The approximate solutions to the system of equations are:
The additive inverse of 7/2 would be -7/2 (option B) Since its. opposite !
A)is the additive inverse of C) ; C) is the additive inverse of A) (not your answer)
B. is the additive inverse for this problem (7/2) so thats how we found that this is your answer (answer)
D is the same thing for the problem (7/2) (not your answer)
7/2 isnt the additive inverse for 7/2 because they are the SAME not the opposite.
+ = - (Positive = negative)
- = + (negative = positive)
The answer to this is choice D
