Answer:
What's the question?
Step-by-step explanation:
-(4/5)*(3/7)*(15/16)*(-14/9) [two negatives make one positive]
=(4*3*15*14)/(5*7*16*9) [simplify 4/16]
=(3*15*14)/(5*7*4*9)
=(3*3*14)/(7*4*9)
=(14)/(7*4)
=(2)/(4)
=1/2
Answer: (x+4)^2 -1
Step-by-step explanation:
42 hours
EXPLANATION:
To find the answer, we should start with the total and get rid of the amounts that we know.
So we know the total is 1,172 in a week, and that 500 dollars of it is for rent.
1,172 - 500 =672.
Now we have 672 left.
We know that it was all spent on employees.
we know it is $16 for each hour.
672 divided by 16 is 42 total hours.
Hope this helps!
We'll use elimination for this system of equations. What variable should get canceled? The x or y? Well to cancel, we need a positive and negative variable.
x + y = 10
x - y = 0
In this case, the y's will cancel out.
Then we will add the x's together and the 10 and 0.
x + y = 10
x - y = 0
Becomes
2x = 10
Now, solve for x. Just simply divide by 2.
2x / 2 = 10 / 2
x = 5
Now we know what the x variable is equal to!
To solve for the y variable, just replace the x variable in one of the equation and solve for y.
I'll use the x + y = 10 equation
We know x is equal to 5.
5 + y = 10
Subtract both sides by 5.
5 - 5 + y = 10 - 5
y = 5
So, both x and y are equal to 5.
