8:50 am
1/3 of 30 = 10 min (so it takes 10 min for him to drive to work)
9:00-10min = 8:50
Answer:
-27 and -18
Step-by-step explanation:
Solve algebraically. Use a variable and an expression to represent the numbers.
let the smaller number be "x"
The bigger number is x + 9.
The two numbers are "x" and "x + 9".
The sum of two numbers means when you add them together. If their number is −45, then:
x + x + 9 = −45
Simplify and isolate "x" to solve in the equation.
x + x + 9 = −45 Collect like terms (numbers that have "x") to simplify
2x + 9 = −45 Isolate "x"
2x + 9 - 9 = −45 - 9 Subtract 9 from both sides
2x = −54
2x/2 = −54/2 Divide both sides by 2
x = -27 Value of smaller number
The bigger number is x + 9. Substitute "x" for -27 and solve.
x + 9
= -27 + 9 Add together
= -18 Value of bigger number
Therefore the two numbers are -27 and -18.
Answer:
73.3%
Step-by-step explanation:
We can express 44 out of 60 as 44/60. Since the fraction viniculum means division, this reaches 44 divided by 60.
In doing so, we achieve the answer 73.33333.... terminating.
Rounding to the nearest place gives 73.3 as our answer.
