Answer:
42 and -50
Step-by-step explanation:
42+ (-50)= -8
If seeds are 8 per pound then you need to find the unit rate and make a proportion with how much she spent. So you can make a ratio of 1(pound) / $8 compared to x(pounds) / $10. Then, cross-multiply.
10 = 8x. Divide both sides by 8
10/ 8 = x Simplify the fraction
1 1/4 = x
So, she bought 1 1/4 pounds of seeds
Answer:
0.6
Step-by-step explanation:
4/7 can be considered a suspended division problem. To find the answer, 4 must be divided by 7. This yields the result 0.57142, which can be rounded to 0.6.
You can only draw one line containing three collinear points. Indeed, for any two distinct points, there's only one line that passes through both points.
<span>Of course, there are countless different ways to write the equation of such a line, but if you graph them (or algebraically manipulate the equations), they all turn out to be the same line.</span>
