we have the expressions
3.2^2-1=10.24-1=9.24
10-0.33*2=10-0.66=9.34
therefore
should be joined by a not equal sign to form an inequality
so
9.24 < 9.34
9.24 is less than 9.34
I’ve completed the question.
Would you like me to elaborate on any point?
Answer:
1.4 pounds
Step-by-step explanation:
to get this ancwer you divide 14 by 10 witch gives you 1.4 pounds
If Ann can build the model in 3 hours, then in 1 hour she gets 1/3 of it done. Likewise, if Sam can build the model in 6 hours, then in 1 hour he gets 1/6 of it done. We are looking to find how long it takes when they combine their efforts, so we will add the two together and set it equal to 1/x, x being the number of hours it takes for both of them to get the whole job done. The equation then looks like this:
. You will have to find the common denominator to add those fractions, and once you do, cross multiply to solve for x.
