Answer:50
Step-by-step explanation: you divide 108 by 2 then round 54 to 50 since 4 is not enough to round to 60
Answer:
sorry, dont speak spanish
Step-by-step explanation:
The x-intercept is a point whose y-coordinate is 0, so (x,0).
Substitute 0 for y in the equation:
The x-intercept is
.
I guess the original expression is 125 = 5^x
If you apply logarithms to both sides, you get:
log (125) = x * log (5) <----------- logaritmic equation
=> x = log (125) / log(5)
Given that 125 is 5^3
you can simplify to
x = log (5^3) / log(5) = 3 log (5) / log (5) = 3 * 1 = 3
There you have the expression as a logarithmic equation and the solution of the equation.
(-10) + 14 + 25 + (-16) Add 14 and 25
(-10) + 39 + (-16) Change 39 + (-10) to 39 - 10
(-10) + 39 - 16 Subtract 16 from 39
(-10) + 23 Change (-10) + 23 to 23 - 10
23 - 10 Subtract 10 from 23
13
*Remember, you can rearrange expressions like this as long as each number keeps its sign. Notice that (-10) had its negative sign the whole time, even though we moved it around.
