You could draw a linear model to express the relationship. The y value will be your inch(es) while your x is your feet. Since one foot has 12 inches, then your slope is 12.
The expanded binomial is 2x^3+3y^2=7
<u>Step-by-step explanation</u>:
- The binomial is not shown in correct expansion. It is written in the wrong format. There is a general format for the binomial expansion.
- The first term should have the highest power. So 2x power 3 will come first. The second term will have power lesser than the first term.
- So in the second term, 3y^2 will be placed. After that, the equal to = operator will be placed. Finally, the value of the expression will be placed.
- So the expanded correct form is 2x^3+3y^2=7
Answer:
Step-by-step explanation:
Let x represent the number of spelling questions in the test.
Let y represent the number of vocabulary questions in the test.
Mrs morals wrote a test with 15 questions covering spelling and vocabulary. This means that
x + y = 15
Spelling questions (x) are worth 5 points and vocabulary questions (y) are worth 10 points. The maximum number of points possible on the test is 100. This means that
5x + 10y = 100 - - - - - - - - - - - 1
Substituting x = 15 - y into equation 1, it becomes
5(15 - y) + 10y = 100
75 - 5y + 10y = 100
- 5y + 10y = 100 - 75
5y = 25
y = 25/5 = 5
x = 15 - y = 15 - 5 = 10
Answer:
2.4 or 2 2/5
Step-by-step explanation:
When you multiply 12/15 and 3 you get 2.4 or 2 2/5
You're going to want to find the area of the whole square, then subtract the area of each triangle from that.
