WHAT THE HECK THANKS FOR THE POINTS THAT MAKES NO SENSE WHAT SO EVER :)
Step-by-step explanation:
Answer:
3x + 5y= 9 is the answer ...
Answer:
x^2 + y = 18
Step-by-step explanation:
The equation is
Let us assume the first number be x
And, the second number be y
Since in the question it is mentioned that the sum of square of a number and the second number is eighteen
That means
x^2 + y = 18
This represent the equation
We know that
<span>An electrician can wire a house in ------------> 20 hours
so
100%----------------> 20 hours
X-------------------> 12 hour
x=12*100/20----> x=60%
that means
</span><span>the apprentice in 12 hours complete the (100-60)----> 40%
</span>the apprentice in 12 hours complete -------> 40%
x hours------------------------------------> 100%
x=100*12/40-----> x=30 hours
the answer is
30 hours
-4=-1b-(1/3)b
-4=-(4/3)b
-4/-(4/3)=b
b=3
-------------------------------
(1/2)3+(5/3)2
3/6+10/6=13/6
-23/3=13/6a
(-23/3)/(13/6)=a
a=-46/13
