Answer:
56n - 7m
Explanations:
Note that according to the distributive property:
a(b + c) = ab + ac
a(b - c) = ab - ac
Therefore, follow the rule above to rewrite 7(8n - m) using the distributive property.
7(8n - m) = 7(8n) - 7m
7(8n - m) = 56n - 7m
Answer:
Step-by-step explanation:
Friends lunch=8+8+8=$32
Blake's lunch=$6
32+6=$40 total
They can ride their bike 12 miles because in 6 minutes they ride 0.8 miles so in 1.5 hours they ride 12 miles. 0.8 * 10 = 8 miles 1 hour so 0.8 * 5 = 4 miles 0.5 hours 8 miles + 4 miles =12 miles 1 hour + 0.5 hours = 1.5 hours
If 12 is 20%, then 24 is 40%, then 36 is 60%, then 48 is 80%, then 60 is 100%
So there are 60 questions on the test.
Answer:
the constant rate of change is 20
