Answer: 3.75z+12
For an equivalent expression, lets simplify the equation.
3/4(5z+16)
multiply both '5z' and '16' by 3/4
3.75z+12
Hope this helps!
Step-by-step Answer:
AN is height, so A is perpendicular to BC. (See image attached).
BN = 18
AN = 24
AC = 40
All as labeled.
ABN is a right triangle, with AB = sqrt(18^2+24^2)=sqrt(324+576)=30
ACN is a right triangle, with CN = sqrt(40^2-24^2)=sqrt(1600-576) = 32
=>
BC = BN + NC = 18 + 32 = 50
It will take them 4.24 hours together to paint the area together
Step-by-step explanation:
If Emily takes eight hours to paint the area then she will paint 1/8 of the house in one hour
Similarly, if Mike can paint the same area in 9 hours, then he will paint 1/9 of the same area
Let x be the number of hours in which they will together paint the area.
If x hours are taken by them to paint the area then 1/x of the area will be painted in one hour
So,
It will take them 4.24 hours together to paint the area together
