Kyle drove x hours
Sally drove x + 7 hours
Added together they both drove 2x + 7 hours
2x +7 = 35 hours
Subtract 7 from both sides:
2x = 28
Divide both sides by 2:
x = 14
Kyle drove 14 hours
Sally drove 21 hours
Answer:
m+n=54 and m=3n+8 is the system of equations that could be used to determine the price of each book.
Step-by-step explanation:
Given,
Total cost of maths book and novel = $54
Let,
Cost of maths book = m
Cost of novel = n
According to given statement;
m+n=54 Eqn 1
the price of the math textbook, m, is $8 more than 3 times the price of the novel
m = 3n+8 Eqn 2
m+n=54 and m=3n+8 is the system of equations that could be used to determine the price of each book.
Step-by-step explanation:
Answer:
79
Step-by-step explanation:
60<xy<100
y -2 =x
if it is prime
y cannot be even
so y could be 1,3,5,7,9
x would then be 9,1,3,5,7
but to be between 60 and 100
x must be 7 or 9
so the number must be 79 or 57
57 is not prime so
the number is 79
Answer:
The answer is 96
Step-by-step explanation:
The answer is 96 because 4^2 is 16 and 8 minus 2 is 6 so 16 multiplied by 6 is 96
