The answer is -12.
All you have to do is substitute the variables for their values and solve.
Hope this helps!
Y = ( 3 / 4 )x - 4 and ( 3 / 2 )x + ( 3 / 4 )y = 16 ;
Then, ( 3 / 2 )x + ( 3 / 4 )[ ( 3 / 4 )x - 4 ] = 16 ;
( 3 / 2 )x + ( 9 / 16 )x - 3 = 16 ;
( 3 / 2 )x + ( 9 / 16 )x = 19 ;
( 24 / 16 )x + ( 9 / 16 )x = 304 / 16 ;
24x + 9x = 304 ;
33x = 304 ;
x = 9.(21);
y = ( 3 / 4 ) × 9.(21) - 4 = 2.90 ;
Which is the best unit for measuring the weight of an elephant?
Answer: Tons
Answer:
1600mm
Step-by-step explanation:
total length of the line segment = length of the first string + length of the second string
to add the strings together, convert the length of the first string to millimetre
1cm = 10mm
95 x 10 = 950mm
950mm + 650mm = 1600mm
