Answer:
-42/4 or -10 1/2
Step-by-step explanation:
So you might want to convert the mixed numbers to improper fractions.
15/4*(-14/5)
Then what you want to do is cross multiply.
Since 5 can go into 15 that would make it into..
3/4*(14/1)
which makes it way easier to multiply.
3*(-14)= -42
4*(-1)= -4
your answer would be
-42/4 or -10 1/2
Answer:
Hence the value of damping coefficient = 1.49071.
Step-by-step explanation:
Answer:
126
Step-by-step explanation:
54 + x = 180
x = 180 - 54
x = 126
Answer:
11j - 1573/10
Step-by-step explanation:
J = 10v /11 +143
collect terms
J - 143 =10v /11
11 (J -143) = 10v
Divide both sides by 10
11(J - 143)/10 = v
v = 11J - 1573/10
Hope this helps!
Answer:
1 < x < 7.5
Step-by-step explanation:
This problem can be solved using given below property of triangle.
Sum of two sides is always greater than third side of triangle.
Difference of two sides is always lesser than third side of triangle.
_______________________________________________
Given
sides length
6.5 units
3.5 units
Third side is 2.5 + x
using the property, Sum of two sides is always greater than third side of triangle.
6.5 + 3.5 > 2.5 +x
=>10 >2.5 + x
=>2.5 + x< 10
=> x< 10 -2.5
=> x < 7.5
using the property, Difference of two sides is always lesser than third side of triangle.
6.5 - 3.5 > 2.5 +x
=>3.5 > 2.5 +x
=> 2.5 +x > 3.5
=> x > 3.5 - 2.5
=> x > 1
combining both we have
1 < x < 7.5
out of the given option none is 1 < x < 7.5
hence, correct answer will be 1 < x < 7.5 and wrong option can be claimed by student.
