Answer:
x = 7.8
Step-by-step explanation:
2.6 + x = 10.4
-2.6 -2.6
x = 7.8
You do the inverse operations to find out x
You write y=mx+b
m= slope
x=variable
b= y-intercept
Answer:
65%
Step-by-step explanation:
78/120=13/20
13/20=65/100
65/100=65%
That shortcut would be a diagonal route. The horiz. leg would be 54 miles; the vertical one would be 31 miles. Using the Pythagorean Theorem, we get distance d = sqrt( 31^2 + 54^2) = sqrt( 3877 ) = 62.3 miles.
He has $5.
2.39 + 1.06 = $3.45
5 - 3.45 = $1.55
He should get $1.55 back
