answer: the system had no solution
Formatting first:
Step 1: (6.2 − 1.6) − 4.4 + 7.8
Step 2: 6.2 + (− 1.6 − 4.4) + 7.8 (commutative property)
Step 3: 6.2 − 6 + 7.8
Step 4: −14 − 6 = 8 (commutative property)
Step 5: 14 − 6 = 8
Step 2 is the associative property (a+b)+c=a+(b+c)
Step 4 is just wrong with -14 instead of 14; seems corrected in step 5.
Answer: He wrote commutative instead of associative in Step 2.
Answer:
yes
Step-by-step explanation:
cause 16 can be split into 8 unlike a odd they cant be split equal
Answer:
Step-by-step explanation:
The problem statement tells us ...
8x = y +3
7x = y -4
Subtracting the second equation from the first gives ...
x = 7
Then ...
y = 7x +4 = 7·7 +4 = 53
There are 7 people, and 53 coins are required for purchase.
Answer:
The y-values of equivalent ratios increase at the same rate as their x-values. The vertical distance between points is constant, and the horizontal distance between points is constant. This forms a straight line.
