Answer:
2sqrt(13)
Step-by-step explanation:
x = sqrt(36 + 16)
x = sqrt(52)
x = sqrt(4*13) = 2sqrt(13)
The inequality should be 4x + 6 > 30
4 times x is 4x, and if anything is greater then smth, you should use > if that number is on the left.
to solve, just do what u would do in algebra, except charging the = into >
4x + 6 > 30
4x > 30 - 6
x > 24/4
x > 6
Answer:
Number of hours= (Total earnings+ Total costs)/$15
Mika worked 18 hours
Step-by-step explanation:
Mika´s earnings function is:
Total earnings= Total Payment-Total costs
The total payment depends on the number of hours Mika took to pint the neighbor's fence:
Total earnings= $15x-Total costs
Now we transform this equation to know the number of hours worked:
Total earnings+Total costs= $15x
(Total earnings+ Total costs)/$15=x
x= $174+$96/$15
x= 18
Mika worked 18 hours
