Hi! I'm happy to help!
To first solve this, we need to make those mixed numbers improper fractions.
To make 4 1/2 an improper fraction, you have to turn 4 into halves (multiply four by 2) then add the extra half, giving you 9/2.
÷(−1
)
Now, we turn 1 3/7 into an improper fraction. We turn 1 into sevenths (multiply 1 by 7) then add the other 3 sevenths, giving you 10/7.
÷(−
)
From here, we need to turn this problem into a multiplication problem in order to solve. Since multiplication is the opposite of division, we need to get the opposite of something, so we use our second fraction and flip it.
×(−
)
Now, we multiply the top by the top, and the bottom by the bottom. (any positive multiplied by a negative gives a negative)

<u>Since we cannot simplify, our final answer is -63/20.</u>
I hope this was helpful, keep learning! :D
Answer:
B. 2
Step-by-step explanation:
For x = 2, w(x) = 3, t(x) = - 1
w(x) + t(x) = 3 + (-1) = 3 - 1 = 2
Answer:
24
Step-by-step explanation:
You need to plug in 3 for all of the x-values
That looks like 2(3)^2 + 5(3) - 9
Then if you simplify it is 2(9) + 15 - 9
Then simplify one last time and you get a final answer of 24
3/4 *7
or
0.75*7
The answer is 5.25
Answer with explanation:
It is incorrect to say that 50% heritability of intelligence means that the cause of the intelligence is 50% genetic and 50% environmental.
<em><u>Because heritability accounts for variations among people, not in specific individuals which means that the cause is not 50% environmental or 50% genetic but rather based on variations among individuals</u></em>
