Then 
Answer: it takes him 63 minutes to run 6 miles
Answer:
42
Step-by-step explanation:
10.5 times 4,the amount of sides of a square, is 42
Answer:
Leon has $15 and Laci has $61
Step-by-step explanation:
Let x = the amount Leon has. So 4 times that plus $1 would be 4x+1. Our equation is:
x + (4x+1) = 76
Combine like terms
5x + 1 = 76
Subtract 1 from both sides
5x = 75
Divide both sides by 5
x = 15. This is Leon. Laci is 4(15) +1, or 61.
Move the expression around so variables are with variables and numbers with numbers: 5/6p-2/3p+1/5-1
create a common denominator for variables and numbers: 5/6p-4/6p+1/5-5/5
simplify: 1/6p-4/5
Answer:
m= -3
b= 4
Step-by-step explanation:
whatever number has x next to it is always slope, that is how you find slope in a equation. To find y-intercept (b) you can just use the other number that doesn't have x to it.
Hope this helps!!!
