Answer:
The best estimate for the solution of the system of equations is the ordered pair (7, 0.5)
Step-by-step explanation:
The way to solve this problem is to take a deep look into the picture, where we can see that the interception between the lines occurs right in x=7. thus, eliminating the first choice.
Next, we can see that the interception is somewhere far from the 'x' axis, hence 'y' variable can not be zero in this point.
Thus, we have our possible solution, without knowing anything else, the ordered pair (7, 0.5).
Remember, a system of equation has a solution when an interception occurs between its equations
Answer:
117 grams
Step-by-step explanation:
So this is a oddly phrased question but I believe I understand it. You need to find 10 percent of 1170 grams and that it 117. And for you information I did use calculator to prevent error so don't worry about that.
Answer:
The original price for this dress was $30
Step-by-step explanation:
If 90% of 30 is 27, we have to find out 10% of 30.
How to find it:
1) You make the 10% of 30 into a proportion
10/100=x/30
(Cross multiply)
100x=300
x=3
2) So now since we’ve found 10% of 30, we add it on to 27.
27+3=30
Therefore, the original price of the dress that Kate bought was $30.
