Answer:
To decide whether to add or subtract, determine if the values of the coefficients are the same or opposites:
. If the values are the same, subtract the equations.
• If the values are opposites or additive inverses, add the equations.
Step-by-step explanation:
Given
Required
How to solve
Options (1) and (2) are incorrect because none of the options eliminate x or y.
For option (3),
- Check for the coefficients of x and y
- If they are the same (sign and value), then subtract; otherwise add
For instance:
Rewrite the second equation
The coefficient of y are the same, so we subtract;
<em>See that y has been eliminated</em>
Answer:
Take 20% of 35000 and add it
Step-by-step explanation:
20% of 35000 is 7000 so we take 35000 + 7000 which would be 42000
Answer:
54.4
Step-by-step explanation:
3.4*16=54.4
First, you'll want to identify the given in the problem.
It costs 100 dollars to purchase all of the shirts and 10 dollars to print the designs on the shirts. The result being a 110 dolar investment prior to his sales. In addition, each shirt is sold for 4 dollars and this becomes the slope of the equation.
Using this info the following equation can be used to find Eric's profit:
P=4x-110
With 4 being the slope.
Overall, after selling the 20 shirts by plugging 20 in for x we get 80-110. So his profit is -30 dollars.
Hope this helps :)
