Answer:
1
Step-by-step explanation:
first, solve in the parentheses then solve from there:
1 + 4 = 5
50 - 5^2 / 25
50 - (5 x 5 ) /25
50 - 25 / 25
25 / 25

Answer:
Nina would have total expenses and sales $156 after selling 4 necklaces.
Step-by-step explanation:
Let <em>x</em> represent the amount of necklaces made and sold.
The initial cost was $140 and it costs $4 to produce one necklace. Hence, the total cost after producing <em>x</em> necklaces can be represented as:
Each necklace sells for $39. Hence, the total profit after selling <em>x</em> necklaces can be represented as:
To break even, the total cost and profit must be equivalent. Hence:
Solve for <em>x: </em>
<em /><em />
<em />
Hence, the break even, Nina would need to sell four necklaces.
And the total expenses/profit would be:
In conclusion, Nina would have total expenses and sales $156 after selling 4 necklaces.
First, use distributive property:
5(2r+6)-12r <em>The original expression; multiply 5 by 2r, and 5 by 6.</em>
10r+30-12r <em>Keep the -12r, just add it on to the end of the number(s) you found</em>
Next, use communitive property:
10r+30-12r <em>What we found in the previous step</em>
-2r+30 <em>Combine the like terms; 10r-12r=-2r, then place the 30 at the end</em>
Done! Your answer is -2r+30.
Hope that helps!
Answer:
y - 5 = (3/2)(x - 2)
Step-by-step explanation:
If two lines are perpendicular, their slopes are negative reciprocals of one another.
The slope of 2x + 3y = 5 is found by solving this equation for y:
3y = -2x + 5, or y = (-2/3)x + 5/3.
Thus, the slope of the new line is the negative reciprocal of -2/3, which in turn comes out to 3/2.
Use the point-slope formula y - k = m(x - h):
Substituting the givens, we get y - 5 = (3/2)(x - 2)
