4 1/2 ÷(−1 3/7 ) please help and hurry
Answers
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.
[tex]\frac{9}{2}[/tex] ÷(−1[tex]\frac{3}{7}[/tex] )
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.
[tex]\frac{9}{2}[/tex] ÷(−[tex]\frac{10}{7}[/tex] )
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.
[tex]\frac{9}{2}[/tex] ×(−[tex]\frac{7}{10}[/tex] )
Now, we multiply the top by the top, and the bottom by the bottom. (any positive multiplied by a negative gives a negative)
-[tex]\frac{63}{20}[/tex]
Since we cannot simplify, our final answer is -63/20.
I hope this was helpful, keep learning! :D

16. A perfect number is one for which the sum of the proper divisors is
equal to the number. (The proper divisors are the ones that are less than
the number and divide evenly into the number.) For instance, 496 is a
perfect number. The proper divisors of 496 are 1, 2, 4, 8, 16, 31, 62, 124,
and 248. The sum of the divisors is
1 + 2 + 4 + 8 + 16 +31 +62 + 124 + 248 = 496.

Answers
Answer:
a = 32
Step-by-step explanation:
This is a right triangle and the square value of hypotenuse is equal to sum of square value of other two side lengths
68^2 = 60^2 + a^2
4624 = 3600 + a^2
4624 - 3600 = a^2

Answer:
b = 30
Step-by-step explanation:

Answers
Answer:
x=-5
Step-by-step explanation:
2(5x-4)=10x-8
-3(3x-1)=-9x+3
10x-8-9x+3
x=-5
The answer you are looking for is -5.
Writing out the equation,
2(5x-4)-x-3(3x-1)
Using the Distributive Property for 2(5x-4) and -3(3x-1),
10x-8-x-9x+3
Using the Associative Property,
10x-x-9x-8+3
Simplifying the similar terms,
9x-9x-8+3
Canceling both "9x" terms, since 9x-9x is obviously 0,
0-8+3, or simply just -8+3.
-8+3=-5
So, therefore the final answer is -5.
I hope that this has helped you. Enjoy your day, and take care.
